Suspension Secrets Adjustable Rear Toe Arms For BMW F87 M2/ Competition

Experience improved traction and cornering stability with our Suspension Secrets F87 BMW M2 / M2 Competition Adjustable Rear Toe Arms.

When increasing the rear camber on your F87 M2 / M2 Competition, it becomes impossible to achieve toe-in. A lack of toe-in will create huge instability when cornering and accelerating, making your F87 M2 / M2 Competition very difficult to drive.

This means you must compromise by setting less negative camber, which results in less cornering grip in order to achieve toe-in.

To solve this issue, we created our Suspension Secrets F87 BMW M2 / M2 Competition Adjustable Rear Toe Arms which feature a far greater range of adjustment. This greater range of adjustment means you can have the benefits of increased rear camber AND toe-in.

The main benefits of our Suspension Secrets F87 BMW M2 / M2 Competition Adjustable Rear Toe Arms are:

Improved rear axle stability when cornering
Increased traction when accelerating
Full control over rear axle toe settings
Easy to adjust with a 17mm spanner
Increased responsiveness during acceleration

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.
