Greg, thanks, and stop being bashful!... just say what you mean

I'm trying out different PSIs... yes, some guys run 40+ hot with their Hoosiers... my goal is to figure out which PSIs yield the best times - trial and error - that is all

Thank you, Travisjb, for the encouragement! I will attempt to post what I really think, but my greatest fear is being redlined/blocked from this post, and life in general. Always here for PM...at your service Greg (this is the only "bow-down" html I could find)

I experimented a lot with tire pressure as well, with stock camber I was using 38.5 front, 35 rear, and after adjusting the camber I found that 36 front 34.5 rear was the ideal for maximum grip on my setup with RE-11's. Everyone will be a little different as it will vary depending on car setup, tires, and driver.

Thanks for the insight. i just mounted 285/255 RE-11's and I wasn't sure what tire pressures would be optimal. One question, wouldn't it be better to have a stiffer rear tire side wall with higher PSI to avoid rolling?

ChrisSlicks

That all depends on how your car is setup. From the factory you have slightly more rear camber than front camber, and the rear can be adjusted to around -2.0 with stock suspension. It's typically the front that rolls the tire edge the most during cornering, it's the heaviest part of the car and experiences the most loading.

The pressures I quoted are if you have after-market sway bars installed with adjustable front camber. With stock sway bars there will be more body roll and you will need slightly higher pressures to compensate.

Oh ok gotcha! Yes I have stock suspension. Another question, I just had an alignment done and had my rear toe at 0 but for some reason they couldn't get my driver side rear camber past -1.8. They said I would have to get a camber kit. Does that sound right?

ChrisSlicks

That sounds right. I think at 0 toe I was maxed out at around -1.8 on the driver's side as well.
