2015-2020 BMW F82 M4 CS Style Carbon Fiber Trunk Spoiler
The factory trunk lid is conservative. RW Carbon's spoiler adds a defined lip in genuine carbon fiber, bonding to the trunk lid with pre-cut 3M VHB tape so no holes are drilled and nothing is permanently modified. 3M Tape install — no drilling. Ships from RW Carbon’s Anaheim, California warehouse.
CARBON FIBER · 3M TAPE · REVERSIBLE
Real carbon fiber trunk spoiler — tape-on, no drilling.
Pair this CS style trunk spoiler with our CS style front lip for the ultimate BMW M appearance.
Genuine carbon fiber, UV clear-coated for high-gloss shine and weather protection. Install: 3M Tape — no drilling. Reversible: Yes — tape lifts with heat.
What Makes RW’s Trunk Spoiler Different
GENUINE CARBON FIBER
Genuine carbon fabric with a matched resin blend — rigid, lightweight, and the deep weave you cannot fake with hydro-dip or wrap.
UV CLEAR-COAT PROTECTION
A final clear coat for high-gloss shine and protection against UV yellowing, road salt and weather.
3M TAPE ADHESIVE INSTALL
No drilling and no bodywork. Pre-cut 3M VHB tape bonds the spoiler directly to the factory trunk lid.
PERFORMANCE STYLE PROFILE
The lip silhouette mirrors the factory performance accessory spoiler at a fraction of the cost.
SHIPS FROM ANAHEIM, CA
Stocked and quality-checked at RW Carbon's Southern California warehouse before it ships to you.
100% REVERSIBLE
The 3M tape lifts cleanly with heat if you ever want to revert to OEM. The factory trunk lid is untouched.

Inside The Build
3M Tape Install
3M TAPE — what the job involves:
- Test fit first — offer the part up dry and check the seam before removing any tape backing
- Clean the surface — isopropyl alcohol on the bonding area, then let it flash off completely
- Surface temp — install above 60°F for the 3M adhesive to bond properly
- No drilling — the factory panel is not modified and no holes are made
- Peel and press — work in sections, pressing firmly along the full length
- Cure time — 24 hours undisturbed before rain or a car wash
- Reversible — tape lifts cleanly with moderate heat if you revert to OEM
- No tuning required — cosmetic part, no ECU work
Ceramic-coated cars: any adhesive-mounted part needs the attachment area polished or buffed to remove the ceramic layer before install — 3M VHB and primer do not bond reliably to ceramic-coated paint. Standard sealants and waxes are fine.

FAQ
WILL IT FIT MY TRUNK LID?
Check the fitment band at the bottom of this page — spoilers are shaped to one specific trunk lid contour and do not carry across chassis.
IS THIS REAL CARBON FIBER OR HYDRODIP?
Real carbon fiber. Genuine carbon fabric with a rigid resin blend, then clear-coated — this is not a printed plastic part with a carbon-look finish.
DO I NEED TO DRILL?
No. This spoiler bonds to the trunk lid with pre-cut 3M VHB tape. No holes and no bodywork.
WILL IT REMOVE CLEANLY IF I SELL THE CAR?
Yes. 3M VHB tape lifts cleanly with moderate heat and patient peeling. Any residue cleans off with adhesive remover.
WHAT IF MY CAR IS CERAMIC COATED?
The attachment area must be polished or buffed to remove the ceramic layer before install — 3M VHB and primer do not bond reliably to ceramic-coated paint.
CAN I DRIVE IMMEDIATELY AFTER INSTALL?
Yes for normal driving. RW recommends 24 hours undisturbed before driving in heavy rain or running through a car wash while the tape reaches full cure.
