Description
The MMX Performance Ultimate Differential Track Pack is a comprehensive drivetrain reliability solution engineered for drivers who push their BMW G8X M2, M3, or M4 hard on track. Designed to address the most common failure points seen during extended high-load driving, this carefully assembled bundle strengthens lubrication control, differential stability, and thermal protection as a complete system.
Rather than upgrading a single component, the MMX Performance Track Pack reinforces the differential from multiple angles, ensuring consistent performance through hard braking zones, sustained high-G cornering, and long track sessions.
What’s Included in the MMX Performance Ultimate Differential Track Pack
High-Capacity Billet Differential Sump / Oil Pan
The MMX Performance High-Capacity Differential Sump is CNC-machined from 6061-T6 billet aluminum and increases oil capacity by up to 2 litres (2.10 quarts). An integrated billet windage tray ensures continuous lubrication under high lateral loads, while internal and external cooling fins improve heat dissipation and temperature stability.
This sump is designed to reduce oil starvation, stabilize differential temperatures, and help prevent “Driving Stability Limited” warnings during aggressive track use.
Product details:
- Direct OE-style bolt-on fitment
- No cutting, drilling, or modification required
- Integrated windage tray for consistent lubrication
- Internal and external cooling fins
- Includes -8AN port for optional external oil cooler integration
Magnetic Differential Oil Drain Plug – M22x1.5
The included MMX Performance magnetic differential drain plug is designed to capture metallic particles circulating in the oil before they can cause accelerated wear. The large magnetic surface area helps maintain cleaner fluid, improving lubrication efficiency and long-term component protection.
Product details:
- Lightweight T6061 aluminum construction
- Anodized MMX Performance finish
- Large surface area magnetic tip
- M22x1.5 thread specification
Dual Differential Mount
The MMX Performance Dual Differential Mount adds a second support point to the factory differential using the OEM secondary mounting location. By significantly reducing unwanted differential movement under load, this mount improves drivetrain stability, traction, and alignment during aggressive acceleration and corner exit.
Product details:
- Engineered for track-focused durability and rigidity
- Reduces differential rotation under lateral and longitudinal loads
- Improves driveline response and consistency
- Direct OEM-style installation
Rear Differential Output Shaft Heat Shield Set
Extended track sessions and aftermarket exhaust systems dramatically increase radiant heat near the rear CV boots. The MMX Performance Rear Differential Output Shaft Heat Shield Set creates a protective thermal barrier that deflects exhaust heat away from sensitive drivetrain components, reducing heat soak and preventing premature CV boot degradation.
Product details:
- Custom-shaped for the rear differential output shaft area
- Protects CV boots from excessive exhaust heat
- Designed for high-temperature track environments
- Helps maintain long-term drivetrain reliability
Built for Serious Track Use
Each component in the MMX Performance Ultimate Differential Track Pack is selected to address proven G8X track weaknesses:
- Prevents oil starvation during sustained high-G cornering
- Reduces differential housing movement under load
- Limits heat soak in critical drivetrain components
- Enhances reliability during extended track sessions
By combining lubrication control, structural stability, and thermal protection, this kit delivers a balanced and durable solution for high-performance driving.
