Will a 245 fit on a OEM front wheel?
Yes 37-38 hot, I have to run around 26-27 cold any more and I get over 40
It's the Humidty out here.

It may the tracks or your driving style but what I have found that works for me is being a little more deliberate with the wheel on turn-in for 2nd gear corners (even 3rd at times). I like to "toss" the car into the corner, inducing a bit of over-steer that I counter with throttle-on. You will set up a bit of a drift which the RA-1s handle very graciously. I find I can break the rear loose and get pointed out of the corner and get back on the throttle sooner this way. Try giving the wheel a bit of a jerk but obviously not so much that you go around, just a little snap to rotate the rear around then back on the gas right away to plant it again. YMMV

FYI, I was getting understeer if I went WAY too hot in the same turns this weekend with my non-staggered setup. When I changed my braking and loading, I got through the turn fine. The grip on this track was not as high as I was expecting.
Add some more front camber. Maybe get some tire chalk for the next event to see what is going on.

George, I will be running oem rears(245's) at all corners. I'm having two of them machined out to fit over the front hubs. I believe this is 70mm. This might be a solution that fits in your budget as far as wheels/tires go.

This is the setup I run now...4 rear AP1 wheels with milled centerbores and 245 tires. It doesn't rub with stock 2001 springs / shocks.
Without other changes...stiffer front sway, alignment, etc...the non-staggered setup dramatically swings the handling bias to the oversteer direction (or less understeer if you prefer). I run a Whiteline front bar and no rear bar to achieve more or less neutral bias...albeit with a little more body roll.

I think the bottom line is that you need more tire. The difference from a 225/245 to a 245/275 in my car was tremendous with the biggest improvement being front grip. I don't think it is as much a staggered vs non-staggered setup as it is the fact that a fast driver with a decent setup needs to run a 245 or larger tire on the front in order to take advantage of the cars potential.
