BUSHES

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
Suspension Secrets' products are designed and manufactured in the UK. Our products are made from billet aircraft-grade 6082 T6 aluminium and corrosion-resistant 316 stainless steel. Our solid control arm bushes use Lemforder bearings for maximum performance and longevity.
 
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.

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.

Do we ship abroad ?

Yes we do, to almost anywhere in the world though remember the postage is often high when shipping anything bulky. Most bulky items we export will go by UPS so you can track the package online and could reach America within 48 hours providing its in stock !

However there are a few countries we do not ship to, some of these include: Thailand, Malaysia, Indonesia, Russia, Nigeria, Macedonia, Syria, Ukraine, Lebanon.

Why is postage on bulky items to some countries expensive compared to some other companies ?

For both yours and our safety we use well known couriers such as DPD Local and UPS for shipping, then we know exactly where it is in the world at any time and we know its going to arrive safely. Shipping small items can be cheap, but items such as bodykits are expensive to ship - we have a very small margin on the postage fees merely to cover packaging. We can now ship using standard post on some items, however using all methods you may incur import charges when you receive the goods for which we cant be responsible for.
