Powerflex Porsche 964 (1989 - 1994) Rear Trailing Arm Front Bush

• Developed for ultimate performance using the toughest materials
• Engineered for the most accurate control of chassis geometry
• Manufactured to be easily fitted without the need for special tools
• Powerflex Black Series bushes are manufactured using a 95 Shore A compound to provide maximum control of chassis geometry.
• This compound can be up to 80% more resistant to load than standard rubber and 25% stiffer than our purple performance material.

• PFR57-106 Has been designed to replace the rear trailing arm front bush where the arm locates onto the chassis. These bushes are no longer available from Porsche unless you buy the complete arm at a cost of over £1000.00.The RS model had a stiffer bush fitted over the standard non RS models, the Powerflex bush will upgrade the standard bushes to a similar stiffness to that of the RS version.PFR57-106 comes with Oil Lite bearings to allow the arm to pivot freely allowing the suspension to work with no loading from the bush with posotive location.
