Drastically improve the acceleration and stability of your BMW E90 / E92 M3 with our Suspension Secrets BMW E90 / E92 M3 Adjustable Rear Traction Arms / Trailing Links.

Our rear lower traction arms are designed to extract the most amount of traction from your BMW's rear axle. They offer the following benefits:

  • Greatly improved acceleration
  • Increased straight line stability
  • More responsive rear axle to throttle inputs
  • Increased corner exit traction
  • Higher corner exit speeds

We designed our adjustable rear traction arms with strength and ease of adjustment in mind. Our solidly mounted arms replace the weak folded plate non-adjustable OEM BMW arms, and as a result our arms do not flex during throttle applications, which makes the rear axle far more responsive to throttle usage, whilst removing unwanted toe angle change. 

Our rear traction arms are also adjustable in length as they are supplied with two shim kits offering an OEM hole position and a fixed increased length position for track use which alters the rear axle kinematics. With the extra traction shims installed in the arms, the rear axle kinematics are altered and traction levels are increased further as the arc path of the control arm is altered to provide extra mechanical grip at the leading edge of the tyre under compression such as when throttle is being applied on corner exit. 

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

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.

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.
