The variables that go into setting up a car for the track get pretty complex for a beginner like me. However, I have read recommendations about tire pressure producing understeer that I find confusing.
I have read on different threads that increasing rear tire pressure increases understeer. I have also read that increasing front tire pressure above 38 psi hot will increase understeer. I'm sure both statements are true, but my question is what is the safest way to increase understeer for a beginner driver?
I realize there are many variables, so here is my current setup heading into Infineon this weekend (should be warm, in the upper 80's):
1) JIC suspension, lowered 1.5". Running full stiff front and 8 dn from full stiff rear.
2) Comptech sway bars - middle position front (can't get my OEM links into the tightest position) and loosest position rear.
3) Advan A048 front, two years old with 2 track sessions, but still plenty of tread and good even wear. R888 rear, brand new. I'm sure mis-matched tires will elicit some opinions, but these things aren't cheap and I am hoping new rear tires will help increase understeer.
Tire pressure is my main dilemma. Based on what I have read and replies to my post on the R888, I plan to shoot for 32 psi hot (starting at 26 cold) for the rears. Sounds like the A048s are round and can run at lower temps as well, so I plan to shoot for 32 psi hot fronts (starting at 28 cold).
The question is, if I feel like I want to increase understeer after a couple of sessions, what should I do with tire pressure? Also, I would appreciate any suggestions on my setup going into the weekend.
