Hey wsup guys I'm slowly starting to get into modifying the suspension of the car(finally) so I was wondering about a couple of the things I was gonna do. I was gonna order the whiteline rca, rear bump steer, and perrin psrs since a friend of mine who tracks quite frequently recommended for me to get it. I recently called a local suspension shop asking their opinion on it and they said I should not install the perrin psrs on a daily driven car because of weather here in southern california causing wear issues?(didn't make sense to me which is why I'm posting this thread). So can anyone give me some advice or enlighten me on this matter? I'm a suspension noob btw and I have only been to two track days but I want to start tracking more often(4-6 times a year) and my current suspension/brake mods are:
-buddyclub race spec dampers
-progress 25mm sway bar
-rear trailing arm bushing
-centric blank OEM replacement rotors
-goodridge SS lines
-racing brake et800(front) and et700(rear)pads
-ATE super blue brake fluid

read this as well and it seemed like a good suspension mod:

other advice towards other suspension mods(endlinks or other bushing that I may not be aware of) would be greatly appreciated as well as I wanna do as many things as possible to see how much of difference it will be when done at once

TIA

 

I always tell people to drive their stock car and let the car tell you what it wants changed (it will tell you once you get good enough - usually you need some time in the middle run group before that happens.)

Do your safety mods first, then work on handling, braking & power depending what your driving style and car tells you it needs - It differs for different people.

Anyway, that is my opinion given my experience.

 

Perrin PSRS allows you to alter caster settings.
If you alter the caster setting without getting an alignment, then yes it will prematurely wear the tires, however just by installing the PSRS will not cause premature wear.

An alignment is a must majority of the time, when doing suspension modifications.

Getting more rigid bushings and spherical bearing in place of your soft rubber parts will allow the car to perform more precise and more consistently, however the drawback is that some most "race" parts will generate more vibrations, and noise inside the cabin. Seems like you're on the right track...

As most will mention... drive what you got, and get as much seat time as possible.
Always make small adjustments.
