For the driver who demands unshakable reliability and performance when the laps pile up, the Track Day Power & Stability Kit brings together three critical upgrades from MMX Performance for the G8X-generation ‎M2, M3 and M4. This thoughtfully-curated bundle ensures your drivetrain keeps up with you—hard braking, high G corners and extended stints included.

What's Included?

1. High-Capacity Billet Oil Pan (Differential Sump) for G8X M2/M3/M4

This CNC-machined 6061-T6 billet aluminum sump increases oil capacity by up to 2 litres and features a windage tray plus both internal and external cooling fins. Helps keep the differential fed and cool under continuous track pressure.

Product Details:

• Direct OE-style fit, no modifications required
• Provides -8AN port for external cooler integration
• Helps prevent “Driving Stability Limited” warnings during high-load driving

2. Dual Differential Mount for G8X M2/M3/M4

To complement the upgraded sump, this mount further solidifies your diff housing. Minimising unwanted movement helps maintain alignment of drivetrain components when you’re loading hard into corners and powering out.

Product Details:

• Engineered for track use with increased rigidity and durability
• Allows your differential to remain stable under lateral and longitudinal forces

3. Rear Differential Output Shaft Heat Shield Set for G8X M2/M3/M4

When drivetrain components heat up during extended performance sessions, you risk thermal degradation. This heat-shield set protects the output shaft area, reducing heat soak and maintaining reliability.

Product Details:

• Custom-fitted for the output shaft path and surrounding zones
• Designed to withstand high-temperature race environments and maintain consistent component life.

Ideal For the Track

• Each component was selected to tackle the common weak links that show up on the track: oil starvation under high G, diff housing movement under load, heat soak in drivetrain components
• Combining sump, mount and heat-shield means you’re not just upgrading one part—you're bolstering the system from multiple angles
• Fits perfectly with the G8X M2, M3, and M4 platforms (both RWD and xDrive variants where applicable)
• Great value when bundled with installation guidance and recommended maintenance (fluid change, torque spec check) to maximise the performance and longevity of the upgrades

Vehicle Applications

• G87 M2, G80/G81 M3, G82/G83 M4
• Supports RWD and xDrive variants (check specific mounting/drive-layout options)
• Installation recommended with performance-rated fluids and proper torque specs
