B7 Diff Riser & Chassis Stiffener

B7 Diff Riser & Rear Chassis Stiffener

This upgrade installs between the chassis and diff box, compressing the material to create a much more rigid connection. The result is a rear end that feels more direct and responsive in corners, while keeping the car flatter with less torque roll.

The B7 diff can typically be raised only 2mm safely with standard risers. This system extends that range, giving you 3mm and 4mm diff height options—with team drivers reporting that 4mm works best on black carpet.

Installation details:

• Remove 2mm from the inner ballstud mount.

• Add 2mm above the D block.

• Add 2mm to either the shock stroke or rod end to maintain previous suspension geometry.

• Raise the C block by 0.75mm (one full pill upward) to introduce 2° of anti-squat, opening up slightly higher roll center options for high-grip surfaces.
