BMW F8X DUAL DIFF MOUNT SELECTION

Ventrax F8X Dual Differential Mount – 7075 Aluminium

Enhance rear differential stability and drivetrain precision with the Ventrax F8X Dual Differential Mount. Engineered specifically for the BMW F8X platform (M3/M4/M2), this mount is CNC-machined from 7075-T6 aluminum to deliver unparalleled strength, control, and durability under high-load driving conditions.

Upgraded from the factory single-point mounting, our dual-mount design adds a secondary support point—dramatically reducing differential movement under torque, enhancing throttle response, and improving overall chassis control.

For lowered or tuned cars, make sure you select the lifted option this bracket has been designed to lift the diff 10mm to reduce driveshaft angles and mitigate drivetrain stress—offering smoother power delivery and increased longevity in aggressive setups.

Why Dual Mounting Matters

The OEM F8X rear diff setup relies on a single mounting bush, which acts like a weak hinge under heavy load. During hard launches, corner exits, or aggressive throttle transitions, the diff can shift and rotate—leading to inconsistent traction, a vague rear-end feel, and accelerated wear. Our dual mount setup eliminates that weak point by locking the diff at two positions, dramatically increasing stability, torque transfer, and long-term durability—exactly what you want when pushing the chassis to its limit.

Consumers and aftermarket experts report that dual diff mounts lead to:

• Reduced drivetrain movement
• Improved throttle response
• Minimized wheel hop
