MMX Performance Rear Differential Heat Shields for G8x BMW M2 / M3 / M4 [MMR55-1607]

MMX Performance Rear Differential Heat Shields for G8x BMW M2 / M3 / M4 [MMR55-1607]

MMX Performance addresses a common driveline failure point with its precision-engineered CV Boot Heat Shields, designed to combat the excessive thermal load generated by upgraded exhaust systems or increased engine output. As heat builds up in the drivetrain area — particularly near the CV boots — factory rubber components often crack prematurely, leading to grease leaks, CV joint wear, and eventual driveline failure, especially under aggressive track conditions. While BMW’s OE solution involves fitting expensive CS / CSL driveshafts costing over £2,000, MMX offers a smarter, cost-effective alternative. These heat shields are crafted from lightweight yet durable T6-6062 aluminum and finished in MMX’s signature polished and anodized gloss black for both thermal efficiency and a refined, OE-style appearance. Compatible with both factory and aftermarket exhaust setups, the shields form an effective thermal barrier that extends the life of CV boots and surrounding components. Each kit includes everything required for easy installation, making thermal protection for your drivetrain straightforward and reliable.
