The MMX Performance G8X M2 / M3 / M4 Ultimate Differential Track Pack is a complete drivetrain stability and thermal-management upgrade package developed for enthusiasts pushing the limits of the G8X platform on track. Combining three critical MMX Performance differential upgrades into a single bundled solution, this package is designed to improve differential cooling capacity, drivetrain stability, and long-term reliability during sustained high-load driving conditions.
Designed and tested in the United Kingdom, this package addresses several common weak points encountered during aggressive driving and extended track sessions, including differential oil temperature management, drivetrain movement under load, and heat soak surrounding the rear differential assembly.
By combining the MMX billet high-capacity differential oil pan, dual differential mount, and rear differential output shaft heat shield set into one coordinated package, the system works together to improve thermal stability and drivetrain control under hard braking, acceleration, and high lateral G-force cornering.
