BMW M3 G80 & M4 G82 G83 Quicksilver M Performance Style Exhaust

Carbonwurks has been working with Quicksilver Exhausts for a solid 5+ years now and our relationship has gone from strengths to strengths. Pretty much every one of our development cars has featured one of their systems and there is a good reason why, they are the masters of making some of the finest exhaust systems money can buy!

Our latest development car is the BMW G82 M4 Competition. This car has undergone a complete upgrade on the carbon side with a whole host of M Performance style parts designed and produced by ourselves.

BMW offer an M Performance exhaust and diffuser which creates a very unique looking back end that is almost a bit Lexus LFA inspired. Carbonwurks & Quicksilver has set out to better the pretty ordinary sounding M Performance exhaust BMW offer and over the course of 6 months worth of development, we collectively offer a fantastic diffuser and exhaust option for those wanting that M Performance style.

Carbonwurks produce the diffuser which includes 3 parts all in 100% full prepreg autoclave carbon fibre. The main carbon diffuser is coupled with a carbon exhaust trim surround which is different to the OEM BMW version which is a standard black metal. To finish the look we also offer a tow hook cover to give a seamless finish. Various bolts, rivnuts and brackets are included for an easy OEM level of fitment.

Quicksilver have produced the exhaust in two parts: OPF-Back – for owners wanting to keep their car emissions friendly; and with optional OPF & Secondary Cat Delete pipes (supplied with pre-programmed terminator connectors so the vehicle does not require remapping, with the ability to revert back to stock without a trace).

The new exhaust and diffuser set-up can be found on our website here – BMW M3 & M4 (G8X) Quicksilver M Performance Active Valve Exhaust System. Have a read a little more in details about these superb parts.

Renault Clio Track Car - Carbonwurks

Donnington Park – Vehicle Testing

As you may or may not know, here at Carbonwurks we are a bit track orientated and inspired! When we are not producing or repairing carbon parts, we are either talking about race cars or going out on track in race cars!

One area of Carbonwurks is the track and race background. We originally were founded off the back of racing and the fascination with the material that is carbon fibre. We have been in the motorsport industry since the early 2000’s and have gained a wealth of knowledge and experience that money just can’t buy.

One of our test & development vehicles is a Renault Clio 200 RS which started it’s life off as an honest hot hatch which quickly with a bit of spec creep, has become quite a track weapon. The Clio has been completely stripped out, the shell and chassis substantially lightened and has gone through a complete nut and bolt restoration where every part has either been upgraded or refurbished where possible.

Renault Clio 200 RS Track Car

Carbonwurks is working on a motorsport division along with obtaining more knowledge with aerodynamics and testing procedures that, further helps us develop our carbon fibre products for road and track cars.

With our Clio not being overly road compliant, we trailered the car up from sunny Bournemouth to not so sunny Donington Park. The shake down included various runs honing in the 3 way adjustable Nitron Suspension as well as bedding in a new drivetrain and braking system. To help us dial the suspension in we brought along our resident front wheel drive racing specialist Alex Morgan who not only has won races and fought for the Clio Cup UK championship title but currently races in the TCR championship as well.

Throughout the day we tweaked the tyres pressures to find their perfect operating temperature getting a great temperature spread over the entire tyre. The suspension was easy to adjust both with slow and fast bump & rebound that helped with consistency in the balance of the car. The Clio has just shy of 300BHP (at time of writing) with help from a Rotrex supercharger. With ramping up the power to 50% more than it rolled out the factory, having the right amount of cooling is crucial not only for the engine but the supercharger unit itself.

As briefly touched on, we test methods out on the Clio to further discover the best way to obtain load pressures on aerodynamical components. Along with load pressures we stress test with shock and frequencies that a car may encounter which would potentially cause wear or failure of parts.

After a long day on track, the only fault was the differential which had a sense of humour failure 30 minutes from the end of the day. We gained more experience with this particular development car both with the handling and performance aspects as well as our testing procedures.

Carbon Fibre DNA - Carbonwurks

Carbon Fibre DNA

When you think of carbon fibre, you’ll likely associate the name/wording with the automotive or aerospace industry. Carbon however makes up around 18% of the human body and is the 2nd biggest element that makes us who we are!

You may be thinking at this point, why is Carbonwurks talking about how I’m made? The answer is quite simple, each carbon fibre part is uniquely different and no 2 parts can ever be identical, much like ourselves.

Although a carbon fibre part from a little distance away can look the exactly the same as another, there are many reason why it wouldn’t do. With carbon fibre parts always being hand made (even in the most automated of manufacturing plants), there are always slightly differences that make each part completely unique.

When producing carbon fibre, Carbonwurks will always endeavour to make each and every part as high quality as possible and to ensure each part fits and looks as best as physically possible. It is however impossible to produce a completely flawless part with zero weave movement, a 100% flat finish or a perfect join for components that are made with a split mould (the vast majority of any carbon parts produced to date).

At first, for those who may be incredibly particular and have laser beam sight, you may think that this sounds like a bad thing but on the contrary! Knowing that the part on your car is not like anyone else’s makes it unique and with that, special.

For sure having a part with terrible weave distortion, a lacquer finish that resembles the surface of the moon or a part that won’t fit the car is simply not good enough but having a few individual unique traits is what make carbon fibre, carbon fibre.

Each carbon fibre part will tell a tale of the person and people who made it. Each person will have a slightly different technique and whether that be in the layup, trimming or finishing of a part you are going to have something that has it’s own DNA.

A little bit of insight in this blog post as to carbon fibre production with each part having it’s own unique identify and remember, you are nearly 1/5th the same as a carbon fibre part (well sort of)!…

BMW M3 & M4 M-Performance Carbon Fibre Pack

BMW M3 & M4 M-Performance Carbon Fibre Pack

Over the past few months we have been working on the Carbonwurks M-Performance Carbon Fibre Components for the BMW M3 & M4 G8X series.

It’s well known the BMW M-Performance upgrades are some of the best available out there in terms of quality and finish. They also look pretty decent on the car once fitted. The only issue with these upgrades is that they are ridiculously expensive.

With a standard M4 Competition costing around £76,000 you’re then looking at an additional £4000 plus for the M Carbon Exterior Styling Pack which only offers a boot lid spoiler, mirror caps, inlets and rear diffuser in Carbon.

If you want the full M-Performance pack then not only is this an after factory build extra but it’s going to set you back an additional tasty £7000 – £8000 (Not including the exhaust). At the time of writing, certain parts of the full M-Performance pack aren’t actually available to purchase from their accessories configurator.

We’re now offering a full suite of Carbonwurks M-Performance style carbon fibre parts for the M3 G80 and M4 G82 & G83 in one easy pack (Or separate parts if you want to build it up in stages) that’s more cost effective without compromising on quality.

The full list of options available are:

BMW M3 M4 Carbon Fibre Front splitter

Our aero parts; the 3-piece front splitter, canards, rear diffuser, rear wing and side skirt extensions add an aggressive / GT4 style to the exterior of vehicle which can then be further upgraded with rear winglets, side breathers and fuel cap!

BMW M3 M4 Carbon Fibre Rear Diffuser

We have also brought in some complimentary Genuine BMW products to round off the M-Performance in the form of interior upgrades such as the Alcantara armrest, Alcantara knee pads, carbon side sills and a few other little extras!

Carbonwurks Carbon Fibre

Carbonwurks Carbon Fibre Testing – On Track at Silverstone

Our background is a little unlike others. We originated from a Motorsport background and even from a very early stage, we set out to produce and sell high-end, performance carbon fibre parts that will stand the test of time. To do this, we had to make sure that these components are not only designed to look great but can also cope with the day to day grind that a car endures as well as strenuous track usage for those owners wanting to push the limits of their car (and perhaps their ability!).

As part of the development programme we run with our components, we test our development cars on track and runways to ensure stability of the parts themselves and to take all important data that can further improve production methods and means of making our products.

Recently we signed off our BMW M3 / M4 G8X programme by testing our development M4 on track at Silverstone circuit. The day was shared with Quicksilver Exhausts who are a long standing partner company that we invited along to help get as much data as possible with an exhaust system being made for a diffuser designed by ourselves.

The testing day at Silverstone entailed various high speed runs not only pushing the cars top speed to check for deformation and stability of the parts but, to also run the car aggressively over rumble strips and kerbs to ensure the parts would be suitable to various violent frequencies that a car can experience. The exhaust system was monitored for heat expansion and tolerances which without doing so and obtaining crucial data may have adverse longevity effects, particularly for those driving in a spirited fashion.

When considering and choosing a company to purchase parts from, one of the key questions should always be “Have these parts been tested and are they safe?”  At Carbonwurks we will always endeavour to put in enough research and development time into our product range to give the highest quality product at an affordable price point.

With over 20 years of motorsport experience both on and off the track, we know the demands and requirements of components and will continue to strive for perfection.

Carbonwurks Receives Made In Britain Accreditation


Here at Carbonwurks we’ve always said that we’re different from the rest when it comes to our Carbon Fibre products.

We’re proud that we don’t import products and instantly ship to the masses unlike a lot of others in the market. Carbonwurks is much more than this as we offer in house; full fabrication, manufacturing, skinning and repair work of carbon fibre components.

To set ourselves apart from the rest we applied to become part of “Made In Britain” which is an accreditation in its own right to show we offer production right here in the UK. The mark itself lets our customers know that we are a trusted company that values transparency, sustainability and ethical business practices.

There will be some products that we still import from outside of the UK (MST Performance, FI Exhausts and various other partner brands) for various product lines that we offer in which case the mark won’t be used against them. This is further to re-enforce our main value of transparency.

You can check out our Partners here:

As part of the application process we have to show / prove to the Made In Britain Team that we either fully manufacture parts in house or that other products undergo a substantial change / transformation at our HQ here in Bournemouth, Dorset.

We’re delighted to announce that we were successful in our application and now have the right to proudly display the Made In Britain mark on our website and join over 1200 other British Manufacturers in doing so.

Repairing Carbon

We don’t often post up about the background less exciting work we do however, this time around we thought it might be a nice little read.

Although we don’t repair a massive amount of carbon it’s something we can offer. Depending on how bad the damage is it sometimes is more expensive to repair than to buy a new replacement part, it also depends on application whether it’s also safe to do so. A Jaguar diffuser came our way recently that is nearly £1,400 to buy new and due to the relatively minor damage it made sense to repair. This repair however was done to the customers budget and being a cosmetic part rather than structural, we opted for a simple wet lay method rather than a vacuum bagging technique.

The diffuser had a fight with a tree stump and unfortunately lost the battle. Part of the lower diffuser had broken along with being deformed. The side bolt positions also had fratured along with the top venturi sections having stress fractures too. This diffuser had also previously been repaired which needed some further refinement.

The first steps were to strip the old cracked resin and lacquer back down to the carbon, probably one of the hardest parts to get right. Go too hard and the carbon comes away, too little and you will always see the cracked and cloudy resin underneath the repair. Once the area has been taken back it’s time to rebuild. The reverse of the diffuser is re-build with a carbon matting and resin mix which is cost effective and yet will give the diffuser a lot more strength.

With the reverse of the part being built up and properly shaped the cosmetic side can start to come together with new twill carbon being laid over. This involves a wetting coat of resin which needs several applications over days with curing time in-between. The side bolt positions are also reinforced at this point with metal spacers being installed and bonded in place before carbon being laid.

With more coats of resin, trimming and flatting in between the carbon starts to form properly. The final part of the repair is completely stripping the old lacquer down, making sure the surface is flat and uniform, the holes at this point are reformed to the original OEM measurements. It’s now time for lacquer.

Once the part has been lacquered the part is then further refined with wet sanding and a course of polishing to bring a super high gloss and smooth finish. Weeks of work involved but bringing an old battered carbon back from the brink is definitely worth it!

How CarbonWurks brings a taste of the racetrack to your road car

The custom carbon fibre parts developed and supplied by CarbonWurks are all about making your car look better – but increasingly bodywork is about performance too.

CarbonWurks director Daniel McKenzie, a championship-winning racing driver, says the Formula One season opener in Melbourne showed how aerodynamic design for race track and road are converging.

New F1 regulations have seen the teams try different approaches to finding the performance sweet spot, with Ferrari’s race-winning car being a particularly good example.

He said: “What Ferrari are doing echoes what’s on their road car and shows how it’s getting to the point where what’s happening on the road cars is intertwining.

“This approach is needed more and more as road car design maxes out – the aero is needed to keep them safe to drive, and you’re seeing not just the styles of GT racers and LMP but even Formula One.

“With road cars so mechanically advanced, the active aerodynamics of F1 cars are the next frontier. That’s the only way you can make these road cars faster now – they need aerodynamics to stay on the road.

“What we do at CarbonWurks is make parts that are cosmetic, but inspired by race performance. They are aesthetically pleasing but some parts we’re developing do have aerodynamic properties to help the car they’re going on. We’re trying to build parts that don’t just look good but also give you more grip and downforce.

“For example, few road cars have downforce and some actually have lift. They would be helped by front spoilers with aero features to produce more downforce at the front. Similarly, a rear diffuser helps with air flow and holds the rear steadier through high speed corners – it’s a similar principle to F1 and GT cars where you can affect the handling of a car through diffusers.”

Sometimes these parts are custom-designed by CarbonWurks, while others are adaptations of existing products: “We take parts that are made for a large market and mass production, and we improve the design – tweak it to improve the concept and make them lighter, stronger, more aerodynamic. We improve what’s already there, and if there isn’t something already there then we make it.”

An example is CarbonWurks’ new front spoiler and canard for the Mercedes A45: “It’s more aggressive, with aerodynamic advantages. It gives downforce and helps put more of the wind around the car. This makes the front feel more positive and reduces lift, which the car would otherwise still produce.”

A45 Carbon Diffuser

A year on – 2016

It’s been nearly a year since the last blog post and thought that a new post really should be put up on the website!

So what has happened over the last year with Carbonwurks?

Well, it’s hard to put into words how much has been going on. From designing and developing a complete carbon package for the Mercedes A45 to covering almost every part on the BMW M3 and M4. We’ve moved into new premises, taken on new staff, developed our new carbon fibre sunglasses range and more than anything, we’ve made friends with some great customers and communities.

The Carbon package on the A45 and A class is starting to come to a close. There are new parts still being designed and produced for the latest facelift A45 which will be available late 2016, however we have covered almost every single part for the A class now. We are particularly proud of the quality being produce on our latest parts which is using Formula 1 technology and implementing that into road car carbon fibre parts.

A45 Carbon Diffuser

Alongside the carbon for the A45 we worked closely with a long standing partner – Nitron Suspension – for a full race ready but still road going coil-over suspension kit. This took a handful of months to develop with testing being carried out to really dial in the best settings. The outcome is a car that really could take it to supercars on a country road or race circuit.

Mercedes A45 Nitron Suspension

The A class and CLA platform we have developed massively over the last year and however it is coming to a close, there are still many new exciting products being worked on.

The BMW side of things has hotted up a lot, particularly over the last 6-9 months. We now offer a complete M performance package without badge taxing people. We stand by quality but also offering parts at sensible pricing. The M4 exterior package was completed earlier this year and recently the M3 has followed with the rear boot spoiler now being available. We are very happy with the progress of our parts for these cars and are always striving to improve further where we can.

M4 Carbon Rear Spoiler05

As the company has expanded with it’s product range we’ve had to move into bigger premises as well as having a larger off site storage facility. New additional staff has also been taken on with the same extremely high standard of workmanship being kept.

A new range of Arch Guards has also been designed and developed with this range of parts continuing to expand to various models and makes of cars. Alongside the other main platforms, we’ve been working on some smaller items for various models of cars that includes mirrors, bezel surrounds, head unit surrounds and tail gate trims.

This year we have also developed our own range of sunglasses which incorporates full carbon frames and temples along with polarised lenses. Another line of products we are proud of and would love to get more involved in the lifestyle range.


So in short, we’ve been pretty busy! There is still a little over 2 months until the end of 2016 and we intent on making the most of it.

All the best,

Daniel McKenzie
