Upgrade your BMW G80 M3’s rear profile with The LAB Type 3 (AK Style) F1 Light Carbon Diffuser — an aggressive, motorsport-inspired enhancement designed to deliver both stunning aesthetics and functional aerodynamic performance.

Crafted from true pre-preg dry carbon fiber, this diffuser is autoclave-cured for maximum strength, precision, and consistency. Unlike cheaper wet-carbon alternatives, our dry carbon process ensures OEM-level weave alignment, perfect color depth, and superior fitment — eliminating the risk of poor installation or parts flying off at high speeds.

✳️ Why Choose Pre-Preg Dry Carbon Fiber

• OEM-Matched Weave & Gloss Finish – Seamlessly blends with factory carbon options for a unified look.
• Lightweight & Strong – Dry carbon construction delivers exceptional rigidity with up to 60% less weight than fiberglass or wet carbon.
• Autoclave Cured – Ensures tight resin control, no excess weight, and a flawless surface finish.
• UV-Protected Gloss Coating – Maintains long-lasting shine and resists yellowing or fading under sunlight.

⚙️ Perfect Fitment Guaranteed

Each diffuser is CNC-trimmed for precise alignment. Unlike many wet-carbon diffusers that suffer from warping, uneven edges, or improper mounting tabs, The LAB’s pre-preg dry carbon design ensures a flush OEM-grade fitment. You can install confidently knowing your diffuser won’t rattle, gap, or detach under load.

💨 Aggressive F1-Inspired Design

Inspired by Formula 1 aerodynamics, the Type 3 (AK Style) features bold fins and sculpted contours that optimize airflow and reduce rear-end drag. This design enhances downforce while giving your G80 M3 an unmistakably race-ready stance.
