MMX Differential Heat Shields for G8x BMW M2/M3/M4

Under intense track conditions, the factory-fitted CV boots on the G8x BMW M2, M3 and M4 are prone to cracking and premature failure due to excessive heat exposure especially when running an aftermarket exhaust. We've engineered precision driveshaft heat shields to provide superior thermal protection, effectively deflecting radiant heat and extending the lifespan of critical drivetrain components. Designed for enthusiasts who push their cars to the limit, our heat shields offer a simple yet essential upgrade for enhanced durability and reliability on and off the track.

Simple yet essential upgrade for enhanced durability and reliability on and off the track.

Upgrading to an aftermarket exhaust system or increasing engine performance generates significantly more heat in the drivetrain area. With the exhaust sitting closer to the CV boots, this excess heat leads to premature cracking and failure of the factory rubber boots. Over time, this can cause grease leaks, CV joint wear, and eventual driveline issues especially under aggressive track conditions. BMW’s response to this well-known issue is to fit CS/CSL driveshafts, which come at an eye-watering cost of over £2,000. MMX offers a smarter, cost-effective alternative that achieves the same level of protection without the need for expensive drivetrain replacements.

Designed for either factory or aftermarket exhaust systems.

MMX heat shields are engineered to provide a strong, effective barrier between your CV boots and the intense heat radiating from your exhaust system. Whether you’re running a factory or aftermarket setup, these shields act as a protective layer to deflect heat away, ensuring your drivetrain components last longer under demanding conditions. Precision-crafted from T6-6062 aluminum, our heat shields are both lightweight and durable. Our signature MMX polished and anodized gloss black finish not only enhances thermal dissipation but also provides a sleek, factory-like appearance.
