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.

Easy to fit, highly functional ++++
Recently bought a 2025 M3 LCI which seemed ok out of the box. Coming from an M5 CS there was obviously less feel and a bit more understeer. 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.
Lovely kit in great quality and workmanship. Good support regarding car setup. Looking forward to having the kit installed and tested in practise.
Superb and fast delivery, very helpful staff and the product is working as it should.
Driving the FERODO DS 1.11 currently, no overheating of the pads, before it was noticeable.
The hole is really moved to the centre of the disc as much as possible, not like other vendors, that cool the inner face of the disc. Recommended!
Great product !
Super easy transaction, superb quality and fast shipping. Thank you
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.
Muy recomendable comprar en esta web porque además de recibir el material te dan valiosos consejos de setup para sacarle el máximo provecho a las piezas adquiridas.
Not only are the products top shelf, the knowledge and after sales support is second to none
Great Product which was supplied & fitted by Suspension Secrets.
Was added in addition to other Suspension Secrets parts to complete a Fast Road set up on my G87 M2.
Adjustable Height to sit the car exactly where you want it but also the ability to change rake angle to improve the front end positivity and reduce understeer.
Often when modifying suspension - it’s at the cost of road manners & comfort. After a few weeks of use I can happily confirm that the ride quality & manners are unchanged.
A very well set up package with quality components.
Very happy customer. 🙌
Very Impressive visit to Suspension Secrets recently.
The staff were fantastic from start to finish.
I was very well looked after throughout the process with regular updates on progress.
As I had travelled a good distance - the work was completed in a timely fashion and the facilities were more than comfortable while I waited.
I’ve had a couple of weeks now to get used to the new set up and it genuinely has transformed the G87 M2.
The car feels completely planted now and prompts much more confidence - in both wet & dry conditions.
Rear is solid / corner exit traction in a different league.
Front is total transformed - huge difference in turn in confidence & actual grip.
Overall very impressive package and surprisingly OG ride quality & driving manners.
This has clearly been tried & tested to achieve these results.
The way it feels it should have been from factory.
Excellent Results & Performance / Along with a Fantastic / Professional Team.
Highly Recommended.

Jordan is amazing. Package got held up in customs for a while and he communicated swiftly and accurately to get the package released
Awesome products. The camber plates look like works of art, pity they are hidden under the hood!
