Perrin Anti-Lift Kits (PSRS)
Hey Guys,
I've got a few of the Perrin anti-lift kits still available (also known as PSRS).
Fits all WRX models 1993-2007 and STi 1993-2004 and Scoobys with Steel front control arms.
£160inc VAT
Normally £195.49incVAT
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 forPositive 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!
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.
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.
Grease Fittings!
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!
Orders placed this week will be dispatched in time for Christmas!!!

I'm quite interested in these as I've heard great reviews (plus you guys are just down the road from me!). From reading the review I'm a little confused though. Does fitting these give a standard car a harder ride?

Lins ref the above statement is this guaranteed I am a bit dubious that they will add that much caster on their own

The PSRS doesn't give a standard car a harder ride.

For fitting the PSRS it usually takes around 2 hours and then you would need an alignment.
If you call our sales team on 0115 9377200 they'll sort you out with prices and any information that you may need.

iirc you have to remove the sump guard and the subframe to get at them. I think 30 minutes is a bit optimistic, but last time I had mine off it was probably no more than an hour (on axle stands) although I don't have a sump guard.

I had a lower brace and all you need to do is allow it to hang on the front 2 fixings, so again this doesnt need removing.
Im not trying to P*** on anyones fire here but its getting silly what garages charge for simple jobs, I understand they have overheads but 2 hours for a job that will take them under 20 mins(6 bolts) is a bit much.

No sump guard to remove, u dont even need to remove the road wheels to fit them, so with a 2 post ramp its a matter of minutes not even 30mins imho,

Looks like perrin are far to important to answer customers queries. Think I will stick with Whiteline then at least they feed back to the customer.
ps not a criticism of TSL at all just of Perrin themselves.

Hey Guys,
I've been speaking with the guys here about a set labour rate for fitting the PSRS and really it would depend on the car.
Traditionally we allow for 2 hours, but some cars may not take as long and some may take longer.
I can however offer a discounted labour rate for the fitting with this group buy. Just give our sales team a call for details. 0115 9377200
