The G8X DRY CARBON FIBER 7 PIECE RACE DIFFUSER/UNDERTRAY is a performance-oriented rear aero upgrade that replaces factory components with a full carbon fiber assembly built for drivers who want their build to stand out from all angles.
Molded from genuine pre-preg dry carbon fiber, each piece is cured under controlled heat and pressure for a tighter weave, superior strength-to-weight ratio, and a deep, UV-resistant gloss finish that holds up over time.
Fitment
Direct-fit for the following BMW models:
G80 — M3 Sedan
G81 — M3 Touring
G82 — M4 Coupe
G83 — M4 Convertible
Installation
