🏁 Engineered for Performance. Built for Precision.
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.

FAQs
Do you offer financing or payment plans?
Yes. At checkout, you can use Shop Pay Installments or Affirm to split your purchase into easy monthly payments. Financing options, including potential 0% interest plans, are shown during checkout and are subject to approval.
Will this part fit my BMW?
Yes. Every product we sell is verified for specific BMW models and chassis. If you want extra peace of mind, you can send us your model, year, or VIN and our team will personally confirm fitment before you order. BMW fitment accuracy is a priority at Legendary Auto Builders.
Are your parts OEM-quality or aftermarket replicas?
We only carry high-quality aftermarket parts that meet or exceed OEM standards. Each product page clearly outlines materials, construction, and finish so you know exactly what you’re getting. We do not sell low-grade replicas or poorly made components.
Where do you ship from and how long does shipping take?
Most in-stock orders ship from our California warehouse within 1–2 business days. Standard U.S. delivery typically takes 3–7 business days depending on location. Made-to-order or specialty items may require additional production time, which is always noted on the product page.
Can I install this myself, or do I need a professional?
Many of our products are designed for direct bolt-on installation and can be installed at home with basic tools. For more complex parts—such as aero components or performance upgrades—we recommend professional installation for best results. If you have questions about install difficulty, just reach out.
What happens if the part doesn’t fit my vehicle?
If there’s a fitment issue due to an error on our end, we’ll make it right. Our team will help resolve the issue quickly, whether that means an exchange or another solution. Fitment accuracy matters to us, and we stand behind the products we sell.
Are your products tested for quality and durability?
Yes. All products go through quality checks and are sourced from trusted manufacturers. We work closely with suppliers and installers to ensure every part meets our performance and durability standards before it ever reaches your car.
Do your products come with a warranty?
Most items include a warranty covering manufacturing defects. Warranty length and coverage details vary by product and are listed on the product page. If you ever have a concern, our support team is here to help.
