This larger bar will reduce unwanted body role and increase the tire contact patch with the road. Included with the PERRIN™ rear sway bar kit are new reinforced sway bar mounts. The larger diameter of the PERRIN Performance™ rear bar adds stress to the weak factory sway bar mounts. PERRIN™ Technicians have designed a new sway bar mount that will not transfer stress to the body of the vehicle and will help the sway bar perform better by locking the bar to the car. The PERRIN Performance™ Lancer Evolution rear sway bar replaces the factory 22mm sway bar with the a larger 25mm PERRIN™ bar.

The factory endlinks have will bend and twist before transferring the load to the swaybar. Perrin's adjustable endlinks will compensate for this. Spherical joints replace the stock rubber bushings and these are made from high quality aluminum. Perrin claims these to be indestructible! Pick up a set for your Evo today!!

NEW ZERO OFFSET
Our new ZERO offset PSRS gives you the similar performance of the normal part, but because the bearing is not offset, there is no need to have the car aligned! This does eliminate the benifit of adding caster, but it also saves the end user up to $100 in installation!

What is the PSRS?
In the Subaru world, these kits are known as the ALK or Anti-Lift-Kit.The anti-lift part of the kit is a very small feature compared to the benefits 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. 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 .300"! 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 tooccur, 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.
