Perrin Positive Steering Response System for WRX & STI
brand new in the box. Version for Alum control arms. $229.99 from Perrin
Also comes with softer urethane bushing option also $24.99 from Perrin
These bushings can be used with our PSRS system to give you less NVH. If you find our PSRS is a little too stiff for you, these can be used to soften your ride.
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.
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!
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.
Urethane Bushing Upgrade
For those wanting something in between the rock solid connection, and the super soft OEM Bushings, the Urethane Bushing upgrade is a great alternative. These are simple replacements for the Delrin Bushing we normally supply. They provide a slightly softer ride compared to the Derin, and transmit slightly less noise through the chassis.
New for 2006, all PSRS have grease fittings installed. No more disassembling the entire front end just to grease the bushings. Grab your grease gun, and grease away!
PSP-SUS-405 for aluminum versions.
