The CSL look, refined by LAB.
Upgrade the front end of your G8X with the LAB Design CSL Grille with Mesh, engineered to give the G80 M3 and G82/G83 M4 a more aggressive, motorsport-inspired appearance while maintaining a clean, premium finish.
Unlike basic open-style CSL grilles, the LAB Design grille features an integrated mesh backing that completes the look while helping protect the exposed cooling components behind the grille.
Manufactured from pre-preg dry carbon fiber, each grille is produced for high strength, low weight, crisp definition, and the premium carbon finish expected from LAB.
Why LAB
- Pre-Preg Dry Carbon Fiber — Lightweight, strong, and manufactured for a clean, consistent finish
- CSL-Inspired Design — Completely transforms the front end of the G8X
- Integrated Mesh — Creates a more finished appearance while adding protection for the components behind the grille
- OEM+ Fitment — Designed around the factory bumper for proper alignment and clean body lines
- Premium Carbon Weave — Carefully selected weave orientation for a high-end, uniform appearance
- Gloss UV-Resistant Clear Coat — Helps maintain depth and clarity while protecting the carbon finish
- Direct Replacement Design — Replaces the factory grille for a clean, integrated installation
Built the LAB Way
At LAB — Legendary Auto Builders, we don’t start with an existing part and figure out how to improve it afterward. We design and engineer the part from the beginning.
From the shape and fitment to the carbon construction and final finish, every detail matters.
The result is a CSL-style grille that doesn’t just add carbon to your G8X — it gives the entire front end a sharper, more complete presence.

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.
