E30 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 E30 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.
These solid subframe bushings raise the subframe 12mm relative to the chassis to correct static camber and roll centre geometry from lowering the E30 chassis in order to reduce body roll, increase rear wheel grip while also straightening out the prop shaft and axles on lowered cars.
Due to the diff being hard mounted to the subframe on E30's, these bushings do increase in Noise Vibration and Harshness (NVH) slightly compared to stock rubber however, are comparable to poly/plastic yet offer superior performance due to aluminium being a stiffer material.
In order to maintain alignment on the differential bushing, our 12mm diff spacers are required.
