Yup. Also realize that shoulder wear WILL happen at autocross. It’s the nature of the beast and even at -5* you’ll see shoulder wear. Rotate front/rear as you see fit to get even shoulder wear.

Don’t get concerned until this happens lol

How was the traction on those Yoko's when worn down that much?

Not bad at all. They're still quick to cords.

I was lapping the car at Gingerman, Corded those tires, threw on BFGs and ran the same time. So yeah, maybe 0.5 second slower over 1:44 course? Not the worst thing.

When I corded my previous set of BFGs, they were over 2 seconds slower a lap.

Hey Guys - I think I am due to for some upgrades/maintenance on the front end of my 2013 BRZ. I think I have a bad bushing/tie rod/etc. I am getting excess wear on the inside edge. After a recent track day, all of my tires look like they should as far as coming off track, minus the inside 3/4-1inch at most is completely smooth. The car drove off track and right on the trailer last event. Looking for ideas for what could be causing what seems to be excessive toe wear on the inside? Drivers side is the primary offender.

I am planning on replacing the FLCA Bushings - Are the SuperPro legal parts? Or are the SuperPro/Buddy Club/or SPL control arms at all legal? Guessing no on the buddy club due to the ball joints.

Alignment Specs:

The second thought on my mind, I found my RCE T2 coilovers came with 500# springs on them vs 400# like they normally do. Think its a good idea to swap to 400?

You could also look into the STI Group N front control arm bushings. Not something we stock but good pieces. Rubber and OEM shape but stiffer rubber.

It sounds like your car is also a track car? 500/500 is nice on track with the right tires and some light aero. There's some personal preference there too. Auto-x is a little different. Do you feel like something needs to change?

My car sees both STX duty and HPDE and TT Duty. No aero atm(other than hood vents), and always on 200tw. I am doing more auto-x than track use lately. I've always been a pretty big fan of how the car is on the road course.

But, seems just to not have the grip(front and rear) I think I should for autox and very loose on tighter stuff, not sure if maybe its too stiff. The car does amazing in slaloms. My other thought is maybe my front coils are starting to wear out/have an issue, but that shouldn't lead to oversteer(I don't think). Rears were rebuilt 2 years ago.

the harder i drive the more i notice how loose my back is. my back came out from me last this weekend and i will be setting my front sway from soft to stiff to try and get some more understeer

[steverife]

Typically, I've experienced that good in the slaloms (stable) tends to be a little pushier in the tight stuff. Is it loose on throttle on exit? If so, it might be on the pushy side and you are getting back on the throttle with a lot of steering input. I describe that as "pushy loose". You could also be dealing with sway bar bind.


Anyway, going with softer rates and adding front camber should help with grip.

Yeah a great road course set up may not work as well for you in STX!

Sounds like you could benefit from a step down in rates or a swaybar adjustment.

BUT...if you've had your rears rebuilt 2 years ago and your fronts never, they could have some decent wear. That's a pretty darn good run. I'd evaluate that and your suspension bushings first. Feel free to PM me to talk more!

well after this weekend, after fixing my stuff, i set my perrin to stiff to try and get some understeer. also i need to stop driving like a complete jackass

Front camber help with rear grip? I am hesetantto add more front camber until I get something figured out on the front. After my last track day, the inside inch of my FR was shinny smooth and FL was about half as much, so I think I have a bad bushing or tie rod in the front, or something?

Corner exit oversteer for sure is a thing, especially in tight courses(we have small venues and 1 medium venue only).

I sometimes thing the car pushes, but I've had a couple of the better drivers in the area drive the car at autox and they both said its tail happy(1 is AWD guy, but can get in a S2k and set FTD in 2 runs).
