BMW M3 (G80 / G81) M4 (G82 & G83) Carbon Fibre Rear Bumper Side Splitter Diffusers

The Carbonwurks M3 (G80 / G81) M4 (G82 & G83) Carbon Rear Side Splitter Diffusers are an OEM Design Manufactured in Genuine Autoclave Pre-Preg Carbon Fibre.

From factory, BMW offer these rear bumper side splitters in a plain gloss black. We have based our own carbon fibre version on the OEM original but at a more cost effective price without compromising quality or fitment. Our design provides an aggressive look for the rear of your vehicle and enhances the styling dramatically. This is made with the same 2×2 twill carbon weave BMW use for their parts.

Please note, the photos currently being showed are for the M4, we offer the same style for both the M3 & M4 that are specific to each car. Please select the correct rear side splitter diffusers for your car in the drop down menu.

Specifications

• Autoclave, Pre-Preg carbon fibre
• 3K 2×2 Twill – OEM weave
• High gloss UV resistant lacquer/clearcoat
• Coated with RaceGlaze 55 high carnauba wax

For those who don’t know much about Pre-Preg Autoclave carbon, this is the strongest and lightest carbon fibre available. The rear splitter diffusers themselves are cooked under immense pressure to give a very uniform and pin-hole free finish. With this being cured at high temps, it ensures longevity of the diffusers. The side splitter diffusers are then finished in a UV, high gloss lacquer before being hand and machined polished and being treated to a high content carnauba wax from our partners Race Glaze.

Installation

Fitment is a direct replacement for the current bumper side splitters. We always recommend using a competent bodyshop to undertake the installation. We standby our quality and fitment of all our parts. With all our products we produce and sell, every component is designed to stand the test of time along with giving as close to OEM fitment that can be achieved.
