Steve is right, I think 50 lbs in the front is too much. Thinking back when I ran the SS tires, I was around 40-45lbs with no rollover on the sidewall. I think 45#'s up front will increase front grip and thus increase rotation slightly. With a camber challenged car you are going to get more wear on the outside shoulder if the pressure is right. Just the nature of the beast and you should be flipping your tires on the rims halfway through their life cycle if you are using a set exclusively for AX. Going to super high front pressures in order to try to achieve even wear and make up for the lack of camber is actually hurting grip, not helping...............
My advice to you Scott, would be to drop the front pressure to 45 lbs and do 1/16" total toe out in the back. If you are taking it to an alignment shop, that is about -.07 on each side. My guess is that you'll have too much rotation with 50 lbs in the rear and then you can start dropping rear pressures and dialing in rotation from there.
Given that this is my first car ever without front camber access, I still stare at the front outside edge of the tires and just shake my head. Stupid SCCA rules.......
How do you know when to turn the front tires? I don't want to find myself staring at holes forming in the outer edge. Right now, with the 1/16" front toe out, the tires
show stress on the outer edge, but the rest seems to be wearing fairly evenly.
I'll try the lower front pressure tomorrow, along with the #3 setting on the Corksport rear bar. I only tried the stiff setting once before, then went back to the #2 setting.
Later I'll redo the rear toe and try just a little toe out, as you suggest. No time to do it now.
Anyone find the stiff rear bar helps the front tire wear? Others claim it does.
Thanks for the ideas.
