Solid Rear 12mm Subframe Riser Bushing Set for the 318ti and Z3.

Solid Rear 12mm Subframe Riser Bushings are designed to extend the life of your rear tires. When you lower a 318ti or Z3, you will begin to wear out the insides of your rear tires due to excessive rear camber. The lower you go the bigger the problem. These solid bushings are designed to raise the rear subframe 12 millimeters to correct extreme negative camber on lowered cars. 

• Reduce negative camber
• Give the tire a better contact patch to the ground
• Restore normal tire wear.

'You can compare to Solid Aluminum mounts in stiffness, but to Poly mounts in vibration'
