Under extreme track use, the factory CV boots on the BMW G8x M2, M3 and M4 are prone to cracking and premature failure due to excessive heat—an issue that becomes even more severe when running an aftermarket exhaust.
BMW has acknowledged this problem, confirming that sustained racetrack driving on G80, G81, G82, G83 and G87 models can generate extreme temperatures at the rear driveshaft gaiters, leading to damage and failure. Their official solution is to replace the driveshafts with CS/CSL variants—at a cost exceeding £2,000.
MMX offers a smarter, cost-effective alternative.
Our precision-engineered driveshaft heat shields are designed to deflect radiant exhaust heat away from the CV boots, significantly reducing temperatures and extending drivetrain lifespan. This simple yet essential upgrade helps prevent grease leaks, CV joint wear, and costly driveline issues—on track and on the road.
Manufactured from lightweight T6-6062 aluminium and finished in MMX’s signature polished, anodized gloss black, the heat shields provide excellent thermal protection with a clean, factory-style appearance. Compatible with both OEM and aftermarket exhaust systems, they deliver CS-level protection without the expense of full driveshaft replacement.
Everything required is included, making effective CV boot heat protection easier than ever.
