Temps depend on the tire used and the rims (width) used. We're optimized for 225/235 tires on 9" rims at the moment, with a spread of 5-15F depending on run time and ambient temps. With 8" rims, outer edges are generally way hotter than the inside and centers.

Higher rear temps isn't a bad thing... I struggle with higher front temps.

10F difference street driving means you probably don't have enough camber for on-track use. Street driving, our car is "warm" on the inside, and cool center and outside. This is purely due to sidewall flex from camber; we run 0 toe front/rear.

Is 17x9 on 225 too much stretching in your opinion? Not worried about the wheel popping off the bead? 225 tires are rated with max wheel width of 8.5'', but it's almost impossible to find wheels in 8.5'' 5x100. Any suspension parts rubbing on 17x9?

What's the hotness in track tire at the moment? Rivals? RS3?

I may be guilty of running 225 on a 9", but these are with tires that are known to run wide...

My tire of choice is still the RS3.

In the Miata world, running a 15x9 with a 225 tire is a very popular setup with the track guys.

Bump. I know there's gotta be more questions :)

ok heres one. im going to tsukuba in a couple weeks. gona be my first time at a track. any tips?

Take it slow, keep the car under control. Tsukuba has walls...

Make sure you got good brake pads and fluid. Otherwise, have fun!

How softly do you grip your steering wheel?

Do you, at all, "hang on" to the steering wheel during hard cornering?

Do I need a full face helmet or will my open face helmet suffice?

I used to. I had to force myself to relax... constantly remind myself to just hold the steering wheel enough to keep in control. Eventually, it becomes natural.

That depends on the organization and track; you'll want to check with the organizer of your particular event.

I think this is why I am so bad at correcting for a spin... I grip the steering wheel and hold on for dear life when the tail end is comin round. :bonk:

I got into a (bad) habit of just letting go of the steering wheel, and catching it when the car's balance "feels right".

I really have no idea where I picked it up, but from what I'm told, it's a drifter thing?

In the s2k, If I do this, it's almost 100% guaranteed that it'll result in an overcorrection and a spin in the other direction, but with the FRS/BRZ, I can unwind and recenter at will.

What senses do you rely on when you track? Can you rate them from most important to least important?

eg., visual, feedback from steering wheel, etc.
