Perrin Positive Steering Response System:

http://www.perrinperformance.com/pro...ory=8&model=26

For ~$225 the list of benefits seems reasonable.

How is the daily drivabilty since it would transfer more vibration to the steering wheel? I already have a AMS front motor mount, which was super stiff when I first installed and livable now that I've had it on the car for a few weeks. I have noticed some rear end squirm under braking if not slowing down in a perfect surface or slightly turning the wheel. We all know how sensitive our steering is already so has anyone put this mod to the test and does it really make that much difference? I also see a zero caster version that won't require an alignment, but if the caster really helps a ton then $80-$100 for an alignment seems worthwhile.

 

+1 on the mod. I've been looking at it...but not sure if its really a "need" for my set up. I wonder if any of the VIII and IX guys have it on.....

 

I've only read on people who track their cars put this on. It helped their track times but never heard anyone running it on their DD. But for $225, it wouldnt hurt to try on the streets

 

its comparable to the "anti-lift kit" for the subaru world. it basically makes your turn-in a little more sharp. i have it on my wrx and its a nice mod. kind of a bcith to install but i thought it was worth the little it costs. my kit isnt a perrin, but a whiteline. they have street and strip models. i have no idea what the perrin one is like.

 

I might have to try this mod out. Thanks for bringing it to my attention

 

in for feedback and info...

I plan on tracking my car and the benefits sound worth it.

 

hey guys,

The effects on everyday drivability is subjective but in my opinion it is not that big of a bother for me. If you are sensetive to NVH then you should get another car than an Evo, haha JK

The only draw back for the PSRS with the added caster is for guys with large/wide aggressive wheels and tires might run into a rubbing situation when turning. The rubbing is usually on the front part of the inner fender liner.


I am finally installing this part on my own Evo IX this week and will give you more drivability feed back as I drive my Evo every day.

 

Sounds good, more feedback is always helpfull when deciding on mods.

 

I spoke to an instructor up at BIR on Monday (fun track day....). He and his kids run the set up on their track cars...ang they hate it. It basically changes the 10:1 steering into 1:10. With a 2.3 lock to lock, no one there said I could come close to using in it (and I track 2-3 times a month). It makes the turn-in super sensitive....I trust the guys opinion, and he drove my car, knows what my set up is...and said save the $.

 

Good feedback, everyone has different needs and wants with their car/race car. This is exactly why we created the part with Zero offset also.

OK, so this thread has been dead for 6 months...

Anybody try PSRS on their X yet?

 

Bump, I could really use some input on if this mod is worth it for a daily driver and a car that sees a road course maybe 5-10 days a year. I'm running the 2010 One Lap of America this year and possibly the zero offset kit might be the best compromise with most of the benefits.

Any feedback or reviews would be great!

 

The other option would be the whiteline front control arm bushing, which is poly and probably a little more forgiving on the street.

though i am a fan of the caster the perrin kit can give you.

you could also run the vorshlag camber plates which add a ton of caster by themselves.....

get it and post a review! it'll be the perfect driving experience all around to compare it vs. the stock part.

 

Ok I'll look at the Whiteline versus Perrin and go with one for testing. Since I already have camber plates I probably won't mess with them to get caster adjustment as well. I'm thinking the car turns in exellent already and don't want it to get TOO jumpy.
