This kit combines a CNC-machined aluminum outer shell with a concentric bore for standard geometry alignment. With the machined shell, and reducing the amount of polyurethane material used, we have increased stiffness by a further 50% over PFF5-301 and PFF5-303, and a massive 250% over the standard OE rubber bushing. The results are incredible, with minimal deflection under steering load and braking, while maintaining a balance of compliance and performance.
This parts fits the following models:
3 Series: E30 3 Series (1984-1991), E36 3 Series (1992-1999), E36 318Ti (1995-1999)
Z Series: Z1 (1988-1991), Z3 (1994-2002)
