Increase the traction and stability of your G80/G82's rear axle with our Suspension Secrets BMW G80 M3/G82 M4 Adjustable Rear Toe Arms / Links.

Whether you G80/G82 is rear-wheel drive only or xDrive, our rear toe arms are designed to improve your BMW's traction in all conditions. Our adjustable rear toe arms give the following benefits:

  • Full adjustability of rear toe angles
  • Increased traction
  • Improved straight line stability
  • More traction at corner exit
  • Enhanced high speed stability
  • Removal of arm flex due to solid mounting

Improve your BMW G80/G82's traction and stability on the road and track with our adjustable rear toe arms. Having adjustable toe arms gives you full control over your BMW's rear toe angles. Uneven toe angles can make a car handle very unpredictably which greatly reduces driver confidence. 

Our rear toe arms are solidly mounted which means they do not flex under acceleration. This results in a far more responsive and sensitive rear axle giving your far greater control over how your BMW drives.

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.

 

Toe

Toe is the angle between each wheel with relation to the longitudinal axis of the vehicle. The animation below illustrates to toe-in, toe-out and zero toe.

There are three types of toe: toe-in, toe-out and zero toe. Each toe setting has a separate purpose and an impact upon directional stability when used on a car. Toe has an effect on three major areas which are: corner entry handling, tyre wear and straight line stability.
 
 
Toe-In
On the front axle of a car toe-in creates straight-line stability, albeit at the expense of some initial reluctance from the car at during the corner turn-in phase. Toe-in on the rear axle again improves straight-line stability, but also induces a slight amount of slip angle which helps when putting power to the ground.
 
Toe-in is more common for fast road use.
 
 
Toe-Out
On the front axle of a car toe-out creates instability in a straight-line. At speed, when a wheel with toe-out is turned, the wheel is pulled rearwards which increases the toe-out angle, pulling the wheel even more outwards. This can even pull the car into yaw. Front axle toe-out can make a car twitchy and unpredictable at high speeds.
 
Toe-out does improve turn-in into corners, and the responsiveness of the front end.
 
Toe-out on the rear axle can create a slip angle which allows for more traction and acceleration, but with a rear-wheel drive chassis it can also lead to unwanted levels of oversteer.
 
Front-axle toe-out is more commonly used for track day or racing applications.
 
Zero Toe
Running zero toe on either the front or rear axles results in minimum tyre wear and power loss. This is because running any level of toe, no matter how small, causes the tyre to scrub in a straight line due to the incurred slip angle, which reduces the rolling efficiency of the tyre.

Zero toe does not improve handling or feedback, nor does it create slip angle - all of which are desirable in performance driving - and as a result either toe-in or toe-out are more commonly chosen depending on use.
