Description

Description

The G8X SQ-B Style Dry Carbon Fiber Rear Diffuser Set 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

Mounting Method: Utilizes OEM hardware. OEM Mounting Points.
Drilling Required: No

We strongly recommend professional installation by a shop experienced with carbon fiber work. Improper installation risks damage to the component or surrounding trim that is difficult to reverse.
