When I started to get a couple phone calls a week about older MINI's that were needing replacement front control arm bushings it was time to offer these hardcore replacements for those that wanted more control of their suspension. Basically, the front A arm bushings suck and over time they simply fall apart which in turn lets your wheel sort of wobble around which will result in trashed tires in a heartbeat. If you can move or wiggle your wheel any or if you find that you have very strange tire wear, it's time to replace those bushings with either OEM units or these pups. Increase steering response while braking and accelerating with the ALTA Performance™ PSRS. The ALTA Performance PSRS replaces the front lower control arm mounts with a solid connection. Getting rid of this overly compliant bushing, gets rid of "wandering" when larger wheels and tires are installed. As a benefit, you will be able to set caster.

What is the PSRS?

Positive Steering Response System, is what it stands for. The PSRS replaces the front control arm, rear bushing. This OEM bushing is designed to be extra compliant to reduce NVH, and make the ride more comfortable. The compliancey of this bushing is not something a performance oriented driver is looking for.

OEM Bushings Installed

Under braking, this OEM bushing has enough flex in it to cause the wheel to move back and forth .500"! This deflection of the wheel causes drastic toe in and toe out changes under braking. These toe changes will cause steering input changes, cause the tires contact patch to change, and even wondering.

When accelerating, this OEM bushing causes unwanted wheel hop, and again toe in and toe out changes. During acceleration, the car will want to follow the ruts in the road, as the bushing flexes back and forth. This is one of the most noticeable changes

Under Braking, after the ALTA PSRS is installed, the wheel will not move front to back period! Since there is no way for toe changes to occur, the steering feedback issues, and wondering under braking all goes away!

Under Acceleration, after the ALTA PSRS in installed, wheel hop disappears, the car will have far less tendency to follow the ruts in the road, and in turn the car will have more front end traction.
Adds Caster

Besides removing all the unwanted flex of the OEM bushing, our PSRS has an offset to where the bushing is mounted. This allows the installer to add 0-1.5 degrees of caster to the front suspension. Caster is the angle at which the steering knuckle rotates on. Adding caster makes the car turn in faster by providing a larger contact patch as the wheels turn on the steering axis. Think of it like camber for your steering!
Anti-lift feature

One of the byproducts with how Alta add caster is the ability to add some Anti-lift to the front end. Depending on how much caster is being added, some Anti-lift can be added to the car. This reduces the amount of front end lift during acceleration. The benefit to Anti-Lift is it keeps the balance of the car in check. During hard acceleration, soft springs, and shocks makes the cars weight shift to the back. This in turn removes weight from the front that keeps the tires planted to the ground. Which is a very important thing when you have all that power going to the front wheels!

NOTE: Offset PSRS will push front wheels forward on car roughly .350"
