Does anyone have any experience with Perrin's Positive Steering Response System?
See http://perrinperformance.com/i-13324...-fr-s-brz.html
Says it replaces the rear bushings on the front control arm. Has anyone bought / tried these? Impressions? Any suspension-knowledgable folks want to chip in? I've been looking for more "steering response" and maybe a little more "feel"; I've searched the forums and while there have been some things on steering feel I haven't seen much on steering response. Any other suggestions would be greatly appreciated & I imagine others will be searching for threads like this one. |

Perrin Front Control Arm Brace Password:JDM Ultimate Lateral Brace With all of this in place, the vague, wobbly feeling I got under heavy braking into a corner was pretty much gone. Still, it was not spectacular and did not seem to do as much as I had hoped. What really made all of this work spectacularly well (and as I had intended) was this brace: Carbing Front Crossmember Brace I had ordered it at the same time as the rest of the items, but it took over 6 weeks to arrive because it was new and had to come from Japan. [I can't find a good link to a Carbing website that shows and explains the brace, so I used this vendor's site for the link.] After installing the Carbing brace, everything came together and worked as I had intended with greatly increased steering response, at the expense of a little more NVH. I also added these at the same time to tame the rear of the car: Whiteline Rear Subframe Bushing Inserts This full setup with stock shocks and springs created handling "magic" with an alignment and some front camber bolts. That is, until recently as now my stock shocks are toast and will need replacement or upgrading to keep my car handling well.

I think this is the same as the Whiteline Anti-Lift bushings/mounts. These always worked great on pretty much any Subaru and the BRZ uses the same basic suspension design. Unfortunately if you autocross they aren't really legal for any class other than Modified since they relocate the suspension pickup points.

Black Tire -- thank you a ton for your input. Especially grateful for your impressions & letting us know about the carbing brace. From what you're saying it seems the brace made the biggest impact and I may order one myself and see what that does alone before I go for the Perrin front control brace / steering response system. Sucks that your shocks are already toast! How many miles do you have on your car? Track time?

I don't know how well the Carbing brace will work without the other items. I just know that it made all my other changes work as intended. I was definitely the most effective piece in that respect.

I drive my car about 1 year with whiteline caster bush (anti lift kit ). and
installed perrin PSRS 2months ago. vibration is much increased during highway crusing. ( 100~140km/h) steering response are not much different from whiteline bush. if you concerned about NVH, I think whiteline anti lift kit is better solution. and both kit will give you 1. crisper turn-in 2. stronger on-center feel Last edited by Yobiwan; 01-30-2015 at 10:14 PM. |

@Black Tire interesting; pretty cool that you're an instructor! well we'll see. I will post my impressions once I get my hands on one to see how as an upgrade alone the carbing brace changes things.
@Yobiwan hmm you almost make it sound like the perrin steering response system is not worth it :P s the NVH increased such that you regret installing the PSRS? worth it in your opinion? thanks to both you and @dwx for mentioning the whiteline anti-lift bushings |

I hear that a lot of guys end up removing the perrin units because of the NVH they produce. I have the Whiteline anti-dive bushings on my car. The change is positive, but very subtle. They keep NVH very low which is a plus.
Hope that helps. |
