Powerflex BMW Z4M E85 & E86 (2006-2009) Front Wishbone Rear Bush, Caster Offset

• 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.

• PFF5-5601G offers additional +0.5° of caster over PFF5-5601 and is a high performance option to PFF5-4601, and aimed at offering greater precision with improved geometry for people wanting the very best from their E46 or Z4. This new part, fitted to the rear of the front wishbone has a hard anodised aluminium outer shell with one of our unique low friction polyurethane centre bushes. The poly/alu combination creates a low friction rotating bush reducing the forces acting on the arm. Lower arm deflection has been decreased by reducing the compliant material within the aluminium shell. Results are less movement in the arm under cornering and braking, improving steering control and feel. This bush is designed to fit the 66mm aluminium bush OE mounting bracket (BMW part 31126783376) Please ensure you have the correct size bush before fitting. Testing during the development of this bush has indicated stiffness gains of 128% compared with the original rubber bush. Our Black Series part increases siffness by 28%, to give an 190% increase in stiffness over the original part
