Keep in mind this is NOT a dedicated track car, it is a full on street car( I long hauled the Power Tour with it, and may do it again) that gets track day'd.

Keep in mind, I did my first event with a good seat in the car and it was very cold 45* high. Dunno if this was the reason for the push or not but I pushed the car further than I ever have that weekend as it was much easier to drive it hard.


I have Strano springs, 1 LE front bar, stock rear bar, Koni Da on front SA on rear, UMI rotojoints on rear, LCA relocation brackets. UMI frame connectors.


I am debating going after more grip. Since I put a seat in the car I realize whats going on with the car when you push it hard.

275 NT-01/ R888 vs a 315 NT-05, I am looking at cost, I have 2 sets of 17x9.5 wheels. If I move to a 315 I will have to buy all new wheels/spacers/studs and consider wheel bearing wear. The 315 NT-05 is a cheaper tire than the 275 NT-01 or R888 and will last longer I would think. Thoughts on which has more grip and life?

I have noticed a push, it has always had one but now seems much worse on high speed corners .
More rear bar help this?
More camber help this?
Am I trying to enter the corner with too much speed?


I only have 1.1 camber in the front as thats all I can get with stock stuff....I am killing the left front outer edge of the tire.
If I slot the lower control arm holes will I have enough tie rod end to set toe? They look way out now.
Would you buy offset LCA bushings and slot, or one or the other?
Or buy a shorter upper control arm?
I feel I need at least 1.8 camber but how will this effect street tire wear?


Anyone used the Global West front lower control arm bushing kit? Thoughts?

Thanks guys all opinions welcome.

Uphill to the body causes roll oversteer. My apologies for misunderstanding, I read "street car" as "one set of wheels for all around use". 315's will typically be faster around a track. But, if you're only running HPDE, you really aren't out to "win" (I think it was Mitchntx that once said "you can't win practice" during a session at the NASA nationals). So, is the extra tire/wheel expense worth the lap time difference? The problem with HPDE is that it's the "super unlimited" class of racing. There are no lap times and no trophies, but everyone shows up to be the fastest car there...with no rules. So, it's an arms race to "win" the open track day. If it were me, I'd run the 275's and be done with it (wheels are cheaper, tires are probably cheaper, etc). But 315's will typically be faster on a track. Or I'd take Stan's advice and buy wheels that allow you to buy used tires from one of the race series and run those.

I think I'm getting old... (IMG:http://www.frrax.com/rrforum/style_emoticons/default/blink.gif)
