I've read that people with 15's are running 40-45cold in front and less in the rears. I'm wondering if my 215/40/17 RT-615's need as much since the sidewall is shorter and the smaller air volume will heat up faster. I've also heard that tire manufacturers sometimes reinforce shorter profile sidewalls which might make higher pressures less necessary. Any ideas?

I also have two SPC camber kits and I'm wondering if I should even install them since my camber has gotten better after adjusting my ride height. Here's where I'm at...
Camber
LF -1.1
RF -1.3 (about 1/8th lower than drivers side so i could get the fronts to match better)
LR -2.0
RR -1.9 (also about 1/8th lower than drivers side so I'd have to vary the height even more to match camber)

Caster is 3.5L and 3.3R in front.
Toe is between 0.00 and 0.08 all around.

The options I'm considering are the following:
Option1: Sell the camber kits and get a progress rear sway bar.

Option2: Raise my fronts for more suspension travel and use the camber kits to get -1.5 camber in the front. I'm currently hitting the bump stops if I make hard turns and hit uneven roads which happens somewhat regularly on Denver streets. Eventually I'm planning to shorten and revalve my Konis in front though.

Option3: Install the camber kits in the rear to reduce the camber to around -1 to -1.5 because I've read that not that much negative camber is needed on our rears. I've also read about people running more than -2 so I'm pretty much lost on where the backs should be set.

Any input is much appreciated.

I ran 42F 36R last year on the same tire, but on stock suspension, and liked it. I didn't play around too much with other pressures though. Mostly I would let a little out later in the day due to increasing temps.

I have converted no less than 5 sets of falken azenis into rubber dust great tire.

back when I used to auto-X. I went with 41ish front, and 29-30 rear. (low tire pressure in the rear can help achieve a greater slip agile for the back tires). If you do any open track events a good starting point is 35 front, 33 rear. -2.5 to -3.0 camber front, rear does not matter that much but I run about -1.5 in the back.
