Reinforce your Quattro Audi with NEW Rear Diff & Subframe Mount Inserts from ECS Tuning!

By locking down the rear subframe and rear differential, rear suspension geometry is maintained and driveline rigidity is improved, resulting in a more "connected" relationship between driver and machine.

Rear suspension feedback is enhanced, rear sway bar upgrades are more effective and a more connected feel between shifter and driveline is created.
