ENGINEERED DETAIL. MOTORSORT-INSPIRED PRECISION.
Complete the rear aero of your G80 M3 with the LAB Dry Carbon Fiber Rear Bumper Diffuser Side Spats — a subtle but aggressive upgrade designed to sharpen the factory diffuser edges and elevate the rear profile with true OEM+ intent.
These side spats frame the diffuser perfectly, adding visual width, definition, and motorsport character without overpowering the factory design. Built for enthusiasts who care about the details.
🔧 Key Features
True Pre-Preg Dry Carbon Fiber
Autoclave-cured for superior strength, reduced weight, and flawless weave consistency — a clear upgrade over wet carbon alternatives.
OEM+ Aero Design
Enhances the outer edges of the rear diffuser for a sharper, more aggressive finish while maintaining factory balance.
UV-Resistant High-Gloss Clear Coat
Deep, glass-like finish designed to resist fading, yellowing, and cracking over time.
Precision OEM Fitment
Designed specifically for the G80 M3 rear bumper for seamless integration and clean alignment.
Perfect Diffuser Companion
Pairs flawlessly with factory or aftermarket carbon rear diffusers for a cohesive rear-end setup.

✔️ Stronger & Lighter — Less resin, higher structural integrity
✔️ Perfect Weave Alignment — No air bubbles, distortions, or resin pooling
✔️ OEM-Matched Appearance — Consistent 2×2 twill weave and gloss
✔️ Built for Longevity — Resistant to UV exposure and daily driving conditions
This is real carbon fiber — engineered, not cosmetic.
🔥 Visual & Performance Benefits
✔️ Adds rear-end aggression without overdoing it

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.
