PERRIN Performance PSRS review

I had a lot of similar experiences as what you posted, but I picked up a tougher-to-turn steering wheel when I increased caster. My large tires were rubbing on the back end of the fenders before the PSRS mod, so after it pushed the wheels forward, I no longer have rub anywhere.

^ Thanks for sharing your experience. I read your other posts and it sounds very similar to what I have experienced for the most part. . .
I ran a NASA HPDE at Blackhawk Farms raceway in South Beloit, IL last weekend. I was running my normal "autocross" alignment just with the added caster from the Perrin PSRS kit. The car felt amazing. I was worried that having a little toe out in the rear would cause the car to be squirrly on braking and corner entry but it was dead solid. Turn-in was unbelieveable thanks to the PSRS kit giving me a better contact patch with the wheels turned and also my DHP splitter/undertray making great downforce at speed. In fact the car was so well balanced - the couple times I threw it into a corner too hot, or got on the gas too hard coming out of a corner - it felt like all 4 wheels slid in unison at the same rate. . . Never felt like it wanted to push to the outside of a turn or come around on me.
Man, I can't wait to get back out!! Autocross this weekend, then a National Tour and Pro Solo in July, then back to MidOhio the end of July I believe!

p.s. I should have a review of the Perrin rear sway bar with Stout Mount up soon. Going to play around with some settings/adjustments over the next couple events. . . but overall impressions so far . . .

I understand the need for the PSRS on cars that are being tracked or raced often, as someone who uses the evo more for daily driving would i see a benefit to the regular adjustable PSRS over the zero? i really don't plan on tracking the car a lot being the daily driver and they are both the same price....

Guess I should have qualified my answer by saying that I would not recommend open spherical bearings for "high mileage, high contamination" driving. For example, someone who lives in northern Michigan who drives their car 30,000 miles a year and all through the winter and lives on a dirt road. For someone living in Phoenix and doing 10-15000 miles I say, SURE, go for it.
You can get 100,000 miles out of a poly bushing, but I doubt any open spherical bearing will last that long no matter the quality of materials.

Basically I have an STU prep car with some geometry correction. 245/40-17 Ecsta XS, Ohlins DFV's 10k/12k springs, whiteline bushings, roll center correction, rear bumpsteer eliminator, whiteline rear sway bar/endlinks and Ferrodo DS2500 pads. Tune and engine are stock.

Any chance of getting some sort of dustshield? I've noticed mine makes noises and when I check the unit, there is generally small pebbles stuck in between the chassis/PSRS bushing; when cleaned out, noise decreases.

are these durable enough to with stand the elements of daily driving in the upper mid west? Very interested in these pieces.
