Audi 8P/8V ECS Differential & Subframe Bushing Inserts
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.
