Pair of MMX Driveshaft Thermal Protection Shields for BMW G8x M2 2023+ M3 M4 2021+

BMW G8x MMX Differential Heat Shields (Pair)

Under extreme track conditions, the factory CV joint boots on BMW M2, M3, and M4 G8x models are prone to cracking and premature failure due to excessive heat exposure, especially when using an aftermarket exhaust system.

We have engineered precision-fit driveshaft heat shields that provide superior thermal protection, effectively diverting 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.

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

Upgrading to an aftermarket exhaust system or increasing engine power generates significantly more heat in the drivetrain area. With the exhaust being closer to the CV boots, this excess heat leads to cracking and premature failure of the factory rubber boots. Over time, this can result in grease leaks, CV joint wear, and eventually drivetrain issues, especially under aggressive track conditions.
BMW’s solution to this known issue is to install CS/CSL half shafts, costing over £2000. MMX offers a smarter, more affordable alternative that provides the same level of protection without the need for expensive drivetrain replacements.

MMX heat shields are designed to create a robust and effective barrier between the CV boots and the intense heat radiating from the exhaust system. Whether you're running a factory or aftermarket setup, these shields act as a protective layer, diverting heat away and ensuring extended durability of your drivetrain components under demanding conditions.
Precision-machined from T6-6062 aluminium, our heat shields are both lightweight and strong. Our unique MMX polished and anodised gloss black finish not only enhances thermal dissipation but also provides a sleek, factory-like appearance.

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