The F20 M135I/M140I BMW chassis is an engaging and fun chassis to drive, but it lacks precision and accurate feedback when pushed to the limit. We developed our Adjustable Rear Camber Arms to rectify this.

The benefits of our Adjustable Rear Camber Arms are:

  • Increased negative camber across the rear axle
  • Greatly improved cornering ability
  • Clearer feedback on rear axle grip limits
  • Improved corner-exit traction
  • Full adjustability gives full control over rear camber angles
  • Reduced rear tyre wear

Our Adjustable Rear Camber Arms are designed to be easy to install and adjust. They can be adjusted easily with a 17mm spanner, without having to remove any wheels.

Transform the handling of your F20 M135I/M140I by installing out Adjustable Rear Camber Arms.

Suspension Secrets' products are designed and manufactured in the UK. Our products are made high quality materials including billet aircraft-grade 6082 T6 aluminium and corrosion-resistant stainless steel, and use motorsport-spec Fluro bearings for maximum performance and longevity.

Geometry Explained

Camber
Camber angle is the angle between the plane of a wheel and the vertical. It is described as positive when the top of the wheel leans outward and negative when the top of the wheel leans inward. Camber angle alters the handling characteristics of a suspension system.

All Suspension Secrets upgrades are designed, developed and manufactured in-house.

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.
