The rear subframe bushings on these chassis are soft, heavily voided rubber from the factory, tuned for isolation rather than control. As they age they let the whole subframe shift under load, blurring rear-end response and throwing off alignment mid-corner. This SuperPro kit replaces them with precision-molded polyurethane that locates the subframe properly while keeping road noise civil.
- Sharper turn-in and more predictable rear grip under power
- Keeps rear alignment consistent under braking and cornering loads
- Durable polyurethane withstands heat, oil, and Canadian winters
- Covers all rear subframe mounting points: 8 bushings and 4 steel tubes
- Part number SPF4328K, rear subframe mount position
Fits:
- BMW 3 Series (E46) 1999-2006, including M3 2001-2006
- BMW Z4 (E85/E86) 2003-2008
- BMW Z4 (E89) 2009-2016
