Refine the presence of your BMW M3 G80 or 3 Series G20 with ASM’s CS Style Carbon Fibre Spoiler – a statement of performance and prestige.

A rear spoiler changes the profile of the whole car. The ASM dry pre-preg carbon fibre spoiler for the BMW 3 Series G20 / G21 / M3 G80 adds a sharper trailing edge to the boot lid, balances the look of front and side aero and gives the rear a more purposeful, motorsport-inspired silhouette.

Dry pre-preg carbon fibre is laid up from fibre sheets that are pre-impregnated with resin and cured under heat and pressure. The result is lighter and stiffer than wet-laid carbon, with a cleaner, more consistent weave. Read more in our guide to dry vs wet carbon fibre.

We recommend fitting by an experienced body shop or tuning specialist. Test-fit every part before final installation, prepare mounting surfaces carefully and use the supplied or recommended fixings. Wash carbon parts like the paintwork, avoid abrasive polishes and protect the clear coat with a quality wax or sealant. Step-by-step advice: How to choose the right spoiler.

Which cars does this rear spoiler fit?

It is made for the BMW 3 Series G20 / G21 / M3 G80. Fitment depends on the exact model, bumper and specification, so if your car has a facelift (LCI) bumper, a different trim level or other aftermarket parts, contact us with your VIN or a photo and we will confirm fitment before you order.

What is the difference between dry carbon and standard carbon fibre?

Dry pre-preg carbon is cured under heat and pressure with a controlled amount of resin, so it is lighter, stiffer and has a cleaner weave than wet-laid carbon. Our guide on wet vs dry carbon fibre explains the difference.
