When lowering your BMW G81 M3 Touring 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 G81 M3 Touring 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

Geometry Explained

Geometry
Suspension geometry is the positioning and angular movement of the suspension arms and the effect that they have upon the movement of the wheel and tyre. It is caused by the different components of the suspension system all moving in their designed paths, which together generate changes in direction and multiple forces on the wheel and tyre, making the steering and suspension operate in particular ways.

Product Development

All Suspension Secrets upgrades are designed, developed and manufactured in-house. This process includes prototyping new products using CAD and 3D printing technology, and extensive rear-world testing with professional racing drivers. Sophisticated motorsport data capturing equipment allows us to measure the handling performance gains achieved by our parts.

Delivery and returns

All parts purchased on our website are shipped internationally free of charge. We accept return requests made within 14 days of receipt of the item.

Effortless & Accurate

The results have exceeded my expectations, I'm really pleased with the car. The ride is similar to stock but it's taken the jitteryness away over small ripples in the road. I was slightly apprehensive that the stock dampers might be exposed but I needn't have worried, the car rides exactly as I'd expect & want from a roadgoing M-car. The real revelation is the steering, I could feel the difference as soon as I turned out of your premises. Gone is the sluggish, heavy response - it's now quick, effortless & accurate, almost as if the power steering had been switched off beforehand. The car feels like it's 200kg lighter but at the same time, more solid & composed. For me, it's a perfectly-judged road setup - thanks again

Recently bought a 2025 M3 LCI which seemed ok out of the box. In the wet there was quite bad understeer and slightly unpredictable transition into oversteer. The CS+ handling package transformed the car. The grip is ridiculous, feel is improved, can really lean on the car. Driving in the wet traction is like it’s dry, extremely stable. Car is predictable, any transition to understeer or oversteer is communicated and feels like slow motion with plenty of time to correct. Feel like all the handling of a CS car with all the comfort or a regular M car. Absolutely love the car now.
