Significantly increase rear axle stability on your E90 / E92 M3 with our Suspension Secrets Solid Rear Subframe Bushes. As standard, the BMW E90 / E92 M3 has large rubber bushes mounted in the subframe connecting the rear subframe to the chassis. 

During cornering, these large rubber bush flex and allow the whole rear subframe to move around, causing instability at the rear. This effect gets even worse as the bushes age in time or as you stiffen the suspension with other aftermarket upgrades such as lowering springs or coilovers. 

To solve this, we have designed, developed and manufactured billet rear subframe bushes for the E90 / E92 M3 which replace the standard rubber bushes in the rear subframe. Once fitted, all flex and movement is removed from the rear subframe mounting points, allowing all of the grip to be transferred directly from the tyres and into the chassis much more directly and quickly. 

This increase in stability at the rear axle not only significantly increases grip levels and driver confidence but it also improves chassis response and feedback. With the flex removed, there is no longer a delay in transfer from the tyres into the chassis. This results in a much better handling car that turns when the driver provides any input. 

This upgrade is a must have for any E90 / E92 M3 being driven spiritedly on the track or the roads to allow maximum grip from the rear axle and create a car with much more feedback and confidence for the driver.

Key dynamic benefits of our Suspension Secrets Solid Control Arm Bushes -for the BMW E90 / E92 M3 include:

• Improved cornering stability

• Increased chassis response and feedback

• Reduced oversteer

• Greater sense of feedback from steering inputs and suspension
