Trevora Front Non-Rub Arch Clearance Kit for G8x BMW M2, M3 & M4

Arch rub is one of the most common and frustrating limitations that G8X platform owners encounter when pushing fitment beyond factory specification. Whether the cause is a wider wheel, a more aggressive offset, a wheel spacer, or a lowered suspension setup, the result is the same; the tire contacts the inner arch liner under load, during lock, or at the compression point of a corner. The TREVORA arch clearance kit is built to address this directly, providing additional clearance in the front wheel arches without asking the owner to cut the liner, pull the arch, or make any permanent change to the car. Each kit includes two precision-cut plates, one for each front arch, manufactured from 1050-grade aluminum. This material grade provides the combination of structural rigidity and workability that the arch liner environment requires; stiff enough to maintain its shape and provide reliable clearance under repeated load cycles, light enough to avoid adding meaningful mass to the front end of the car. The plates are precision-cut for direct fitment to the G8X front arch structure and mount securely using the included hardware without modification to the surrounding body.

Carbon Fiber Construction

• Constructed using high-quality autoclave-cured pre-preg carbon fiber for superior strength-to-weight ratio. Each component is engineered and prototyped in-house using advanced CAD modeling and 3D scanning to achieve precise factory-plus fitment. A UV-resistant clear coat protects the clean weave pattern and maintains finish quality over time, ensuring long-term durability in both daily driving and high-performance environments.

Frequently Asked Questions

• What vehicles is the TREVORA G8X arch clearance kit compatible with? The TREVORA G8X Front Non-Rub Arch Clearance Kit is compatible with the 2023 and newer BMW M2 G87, the 2020 and newer BMW M3 Sedan G80, the 2022 and newer BMW M3 Touring G81, the 2020 and newer BMW M4 Coupe G82, and the 2020 and newer BMW M4 Convertible G83. Fitment on other BMW models is not confirmed.
  Will these plates completely eliminate arch rubbing on my G8X build? It depends on your specific configuration. For many common aggressive fitment setups on the G8X platform, the plates provide sufficient additional clearance to eliminate rubbing under normal driving conditions. For extreme setups at the outer limits of fitment, the plates significantly reduce contact even if they do not eliminate it entirely. Effectiveness is determined by the combination of wheel diameter, width, offset, tire profile, and suspension setup in use. If you are unsure whether this kit will resolve your specific rubbing issue, contact Bulletproof Automotive with your fitment details before purchasing.
• Does installation require cutting or drilling the arch liner? No. The TREVORA arch clearance plates integrate directly into the G8X front arch structure using the included hardware without cutting, drilling, or any permanent modification to the car. The installation is fully reversible.
• What is 1050-grade aluminum and why is it used for these plates? 1050-grade aluminum is a commercially pure aluminum alloy known for its high corrosion resistance, good workability, and structural consistency. In the arch liner environment, these properties translate to a plate that holds its shape reliably under repeated suspension cycles without cracking or deforming, resists corrosion from road debris and moisture, and adds minimal mass to the front of the car. It is a practical material choice for a component in this position.
• Does this kit cover both front arches or just one side? The kit includes both a left and a right front arch clearance plate as a complete pair. No additional purchase is required to cover both sides of the front end.
• Is this kit compatible with wheel spacers and lowered suspension? Yes. The kit is specifically designed with compatibility for wheel spacer and lowered suspension fitment setups in mind, as these are among the most common configurations that cause arch rubbing on the G8X platform. The effectiveness of the plates will still depend on the degree of lowering and the specific spacer thickness in use.
