Suspension Secrets Eccentric Rear Control Arm Roll Centre Correction Bushes - BMW 1M

When lowering your BMW 1M many aspects of geometry are altered that need correcting. One very often overlooking but important aspect is roll centre. The roll centre position of a vehicle determines how stiff the car feels through the corners and can cause the car to become unpredictable out on track if it is altered too much when lowering the car for track use. 

Our eccentric rear control arm bush is designed to replace the OEM solid bush in the rear hub where the rear lower control arm (coffin arm) attaches to the upright. The offset bush can then be installed in the correct orientation to correct the rear roll centre, improving handling and stability significantly. 

With the eccentric bush installed and the rear roll centre corrected your BMW 1M will have more stability through the corners and the front to rear balance of the chassis will be restored allowing for more driver confidence and lower lap times. 

Benefit from: 

• Improved Corner Exit Traction
• Restored Chassis Balance After Lowering 
• Corrected Rear Roll Centre
• More Stability at Apex 
• Increased Driver Confidence 
• More Rear Axle Grip
