Quick Overview

The BMW M3/M4 in general is a great looking car with plenty of aggression, the rear however lacks with the flat OEM diffuser. On a lot of high performance cars you tend to see a nice Venturi effect rear diffuser, Carbonwurks brings that needed look to the M3/M4 with a bold and defined Carbon Fibre diffuser.

The BMW M3/M4 in general is a great looking car with plenty of aggression, the rear however lacks with the flat OEM diffuser. On a lot of high performance cars you tend to see a nice Venturi effect rear diffuser, Carbonwurks brings that needed look to the M3/M4 with a bold and defined Carbon Fibre diffuser.

The Carbon rear diffuser is made up of lightweight and strong Carbon Fibre and reinforced with glass fibre. The Diffuser is then finished off in a high gloss lacquer, after which the carbon is hand polished and sealed in with a very high carnauba content wax to give both depth and protection.

The Diffuser is a direct replacement for the OEM plastic Diffuser, no modifications are needed and is a quick and easy install. Professional installation is recommended however the Diffuser can be changed over in under 5 minutes with only 2 bolts either side and clips holding it to the car.

Every single diffuser is throughly checked for fitment and is tested on our rig to make sure the diffusers fit perfectly every time.

    After searching the internet, speaking to other companies (including BMW) I purchased for my 66 plate M3 a Carbon Fibre Rear Spoiler, Carbon Fibre Rear Diffuser and a Carbon Front Spoiler/Splitter. I ended up driving to meet Daniel (CarbonWurks owner) at a body shop near his business. It was a couple of hour drive but worth the extra money and travel time. Everything was fitted incredibly well, all the parts were finished to a very high standard. I would recommend them. My mate who has an M4 has the same parts fitted to his car, he was equally happy.

    :

    Quality is superb, can’t fault the finishing – 10/10
    Price is a fraction of stealership’s cost – 10/10
    Fitment is very good considered it is aftermarket. No modifications required as it clips straight on with a tiny bit of encouragement. Both side of the holes line up perfectly – 9.5/10
    Friendly service, prompt and detailed responses – 10/10
    Super fast shipping (5 days from UK to New Zealand) and manage to keep the tax man away – 12/10
    Overall can’t be happier with purchase

    Amazing service, received the product next day and as described. Had a bad experience with a company called German Rush where they never despatched the product and I am still waiting for a refund (Avoid these idiots). Happy to have dealt with Carbonwurks and will be using them in the future and recommending to all my friends.

    Since picking up my M4 at Christmas, I have been contemplating adding a rear spoiler and diffuser to “properly finish off” the rear end of the car. Having recently seen a couple of M4/4 Series with the BMW Carbon pack, I decided to take the plunge.

    After some scouting on the web, I contacted Dan at Carbon Wurks to see what they could do for me. A like minded exchange of thoughts ensued, and on Thursday morning I promptly ordered their M4 Rear Spoiler and Diffuser. Dan was kind enough to agree to a discount for ordering both at the same time (£530 total) and also offered me free next day postage and packaging.

    By 09:20 the next day, I had confirmation that there was a large package sitting in my hallway, so I rushed home from work last night to break it open and have a peek at the Carbon Fibre goodies. I was not left disappointed! Carbon Wurks had clearly taken the time to ensure that both of the items were exceptionally well packaged and there was going to be no chance of either item getting damaged in transit, this is something I appreciate as it avoids the disappointment of something turning up but having to go back straight away because the delivery company don’t give two shi*s!

    Moving onto the Spoiler and Diffuser themselves, both are finished to a very high level and are a perfect fit for the car. The spoiler in particular, is absolutely spot on for the dimensions of the boot lid, which just makes fitting it so much easier. The Spoiler came with the 3M tape already applied, so all I had to do was ensure the boot lid was thoroughly cleaned and warmed up a bit with a hot air gun and then it was simply just a case of peeling back enough of the tape to get it into position on one side and then removing the rest of it. Job was done in less than 20 minutes and it’s bang on.

    The same can be said for the Diffuser, the quality and finish is excellent, so it was quick 10 minute job to undo the two bolts either side, remove the panel that was originally in place, clip the new Carbon Fibre Diffuser into place and then but the bolts back in. Again it’s a perfect fit with no issues at all.

    All in all, I’m really pleased with the service, quality and finish of the items provided by Carbon Wurks. I always like to ensure praise is made public when a company gets something right, as lets face it that’s how they generate the majority of their business. So for that reason alone, I am highly recommending Carbon Wurks to anyone who wants to add a little Carbon Fibre styling to their BMW, Merc or Audi.
