I'm probably not remembering correctly. It was quite awhile ago when we talked out his experience/setup at packwood.

Oh, you'll be fine. The v710 doesn't have the same sizes available as the A6, anyway, so it is a different conversation. For the A6, you're comparing 225/40 to 225/45, so there is no width to be gained by going larger. For the v710, though, you're comparing 215/40 to 225/45, so you do gain width by going larger. Still, I would guess that the 215/40 is faster, due to gearing, but then again I have found that I was faster with 225/50 than 205/50 on my 16" wheels, so I don't really know. The only real way to find out is for you to try both.

Code:
Size              Price   Tread    TR Diam    Calc Diam
225/40ZR17   $257    8.9"      23.8"        24.09"
225/45ZR17   $257    8.8"      24.7"        24.97"
245/40ZR17   $266    9.3"      24.5"        24.72"
Edit: The diameters listed on TR for these Hoosiers do not match the calculated diameters for the printed size. I added a column to the above table to show the differences. This sort of thing is common with racing tires; even street-class autocross tires are often wider and shorter than their calculated sizes. For example, the calculated diameter for a standard 215/45/17 is 24.62", which coincidentally rounds to the same 24.7" that TR lists for the 225/45/17 Hoosier A6.

Ian Basford, who was at the PW NT last year was running 245/40 Hoosiers on his SVT without rubbing as well, but I'm not too much of a fan of that size since it would be taller than stock. A good set of struts or an H&R front bar eliminates rubbing as well.
I'm pretty sure that Ian said that he ran the 225/45 Hoosiers.

do you ever pull yourself back and forth towards the steering wheel trying to generate more speed out of corners?? ya know, trying to get the momentum going again?? haha i do this every so often and people look at me like i'm nuts!

i tried downshifting a few times, and the car just doesn't respond well to that. plus i've heard it actually adds time when you downshift.
That's funny, haha... Coming out of corners is when I often start conversations with passengers about what is going on. "So, this is where I hate my motor. Anyway, I'm going to try that offset gate up there without lifting this time, we'll see how it goes." ... and etc. Lol

I'm flat out on just about every corner exit, but I'm just sitting there waiting, lol. Not much happens at 3k, and not much you can do about that. Grabbing 1st gear is usually just too unsettling. Short wheel/tire combos help a bit, but the SVTF's tall powerband and tall gearing is just too far from ideal for autocross. At least it is fun to daily. Compared to my car, Pete's wagon just kind of falls on its face after 4k, which would annoy me on the street.

Damn this thread is getting OT
This is part of why I am so impressed at Bill Zerr's driving. Really awesome to win over a field of Mini's and 3's. Way to go, again, guy

in my SVT, not so much..
