Improve braking stability and steering accuracy by install the Suspension Secrets Solid Front Control Arm Bush for the BMW F80 M3/F82 M4.
The standard BMW front control arm bushes are made from soft rubber. This rubber flexes when driving fast, causing the steering to feel vague at the limit. These rubber bushes also flex when braking hard leading your M3/M4 to feel nervous or unstable.
To solve both of these problems, solid front control arm bushes are required. Our solid bushes are designed as press-fit replacement for the OEM BMW control arm bushes. As our bushes are solid, they eliminate all of the issues caused by soft rubber bushes. Instead you gain improved braking stability and steering accuracy at the limit.
The key benefits of our Suspension Secrets Solid Front Control Arm Bush for the BMW F80 M3/F82 M4 are:
- Increased braking stability
- Improved steering feel and accuracy
- Reduced understeer
- Increased sense of connection to the road
Further Reading
As standard, the OEM rubber bushes used by BMW are quite soft. They are built for refinement, flexibility and durability. Rubber bushes are quiet and are ideal for a car that is designed to be used frequently.
Unfortunately, when used in a performance application, rubber bushes have quite a few downsides. When braking hard, the OE rubber bushes flex. They flex so much that the wheel assembly moves rearwards as the car brakes. This causes unwanted toe geometry change which causes the car to feel very nervous and vague when braking.
The flex in rubber bushes also causes understeer and the steering wheel to feel very inaccurate during cornering.
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.
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.

Suspension Secrets F80 M3/F82 M4 Competition Solid Suspension Bushes are designed and manufactured in the UK. The bushes are CNC-machined from billet 6082 T6 aluminium, and the rubber inserts are sourced from a renowned high-performance OE manufacturer.

Installation was straightforward. My car is a AMGGTC Track you only I was getting outside where on driver side front I leave for the track this Thursday for three days of DE driving I’ll let you know how it goes.
I came across Suspension Secrets by chance on youtube, and decided to check them out. their offering is very structured and website contains a lot of cool information about racing and suspension in particular. Matt is extremely knowledgeable on the subject, and quality of the product is superb. I ended up buying the Track Package for 992 GT3, which transformed the car. They also gave me full specs on how to set everything up. Cold not be happier, I'm your customer for life now!
Worth the purchase price and time from the UK, well built hardware that looks like jewelry for the car.
