E46/Z4 Solid Subframe Raising Bushes
Based on first hand experience testing stock rubber and various polyurethane options we consider our solid subframe raising bushes an absolute must for any E46 chassis whether daily driven or a dedicated track car.
These bushes make the back end feel tight, rigid and responsive improving the control and feedback to the driver for a superior driving experience whether cruising around town or pushing your limits on track.
The CMP solid subframe bushes are unique in that they raise the subframe relative to the chassis to correct the roll centre geometry from lowering and reinforcing the E46 chassis in order to reduce body roll, increase rear wheel grip while also straightening out the prop shaft and axles on lowered cars.
These bushings produce negligible increase in Noise Vibration or Harshness (NVH) compared to stock rubber as suspension and drive line components remain isolated due to their own respective bushes.
