Details

Please note: This product is not kept in stock at our warehouse. It is sometimes shipped directly to you from Alta or shipped to our warehouse and then to you. This may increase order processing/shipping time frame. These are priced as a set of 2. When I started to get a couple phone calls a week about older MINIs 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. Over time they simply fall apart, which in turn lets your wheel sort of wobble around resulting 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 Performanceâ„¢ 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.

Compared to the 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, the Alta 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 adds 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" Sold as a set of 2.

Hi,
Got the distick promptly. Thank you for doing buisness the way it should be done -- I'll be back again. Your prices and service are excellent.
Cheers,
Susan
Susan Thanks so much, I installed the MSD coil, MSD 8.5 mm wires and Iridium plugs. Mini runs much better, even idles at lower rpms and seem smoother in all gears.
I'm thinking it will pay for it's self in gas saving in short order.
Thanks again for offering these products.
Best Regards,
Ron Garcia
Ron Hi,
I recently purchased the belt tensioner from Alta and had it installed. Had I only known over the past several thousand miles that my shock was bad, I would have changed it sooner. The shop guys brought the old one out to show me that it was completely useless. Since replacing it my mileage has increased dramatically, and performance as well. apparently the drive belt was slipping on the super charger. And power, all I can say is "Yeah, Baby". Thanks guys for making this part available.
Best Regards,
Ron
