Description:
Like our other PSRS designs, you get complete control of your Subarus front end. By removing the soft and sloppy rubber bushing you increase steering response while braking and accelerating. The PERRIN Performance PSRS replaces the front lower control arm mounts with a solid connection using a teflon lined sphearical bearing. Getting rid of this overly compliant bushing (AKA the Tennis Ball), gets rid of "wondering" over ruts in the road, and strange steering feedback under heaving breaking and accelerating. On the standard PSRS we offset the bearing/pivot point which provides roughly 3 degress more caster to your front end. This added caster makes the car feel like it steers faster and provides more front end grip while cornering. The added benefits to the standard offset type PSRS are great, but do require a 4 wheel alignment after installation. If you do not want the added cost of an alignment, you may consider the new ZERO PSRS for your 08+ WRX/STI or 05+ Legacy.
What is the PSRS?
These kits are also known as the ALK or Anti-Lift-Kit. The anti-lift part of the kit is a very small feature compared to the benifits of the solid type connection the PSRS makes. Eliminating the OEM super soft bushing provides significant improvement in how the car steers during hard cornering and even in a straight line. So P.S.R.S stands for Positive Steering Response System. 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 compliancy 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
PERRIN PSRS Installed
Under Braking, after the PERRIN 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 PERRIN 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 almost 2 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!
On the Legacy GT, the 2008 WRX, and 2008 STI adds roughly 3-3.5 degrees! This puts your car close to the magic 5-6 degrees of total caster!
Anti-lift feature
One of the byproducts with how we add caster is the ability to add some Anti-lift to the front end. 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 trying to keep tires planted firmly on the ground while accelerating out of corners.

Okay, word association time -- what comes to mind when you think of the word "Oregon?" Maybe trees, or the people who hug them? Possibly, but if you're a speed freak like us, you probably think more along the lines of "Rally America" and "Perrin Performance." Perrin, a part of the Alta Performance Group, began manufacturing specialized aftermarket parts more than a decade ago. They cater especially to high-power sport compact cars, including Subarus, Evos, and more. Perrin has the heavy-hitters of Japanese all-wheel drive performance covered with parts that are built in the U.S., and just as importantly, built to last. With the full line of Perrin Performance products available, Andy's Auto Sport is here to help turn your car into a beast!
Q: What is an anti-lift kit? Why buy one?
A: Anti-lift kits are components designed to prevent the front end of your vehicle from lifting up during heavy acceleration as well as preventing it from diving too much under hard braking. This is especially important in performance applications such as rally racing where soft springs might be used to maximize suspension travel. The soft springs allow the front end to dive and lift depending on brake or throttle application. With anti-lift kits fitted you can still utilize a softer setup and maintain excellent vehicle control and handling dynamics. In addition most of these kits utilize a metal spherical bearing or uprated urethane pieces in place of the sloppy OEM rubber bushings to provide crisp steering response, reduced wheel hop, and increased overall handling capabilities. There is also the added advantage of modified castor angles which can provide many benefits in the steering and handling department. In short this one modification has a ton of performance advantages making it one of the best bang-for-your-buck products that you can buy.
