MMX G8x BMW Differential Heat Shields (Pair)

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.

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 aluminium, 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.

With everything you need in one package, protecting your CV boots from excessive heat has never been easier.

- Statement from BMW

"Extreme racetrack operation leads in case of the G80, G81, G82, G83 & G87 and the associated Competition models to high temperatures at the gaiters of the rear output shafts on the final drive unit side. In the event of gaiter damage that indicates this cause of damage, alternatively also the more temperature-resistant rear output shafts of the special models G80CS, G82CS & G82CSL can be installed in the workshops."
