Measured Performance Differences Between 275 vs 225 Hoosier A6's

Bias ply tires SUCK to autocross on BTW. We tried some of the american racer 13x10s (IIRC) and when they finally got hot enough, they were about as sticky as the a6s, so cheap... but so hard to drive, totally different and inconsistent and just a pita. I'm sure for track days it wouldn't be nearly as bad tho.

It is step 1. Most people are still waiting for a street and/or medium compound more akin to NT01/RA1(cheaper).
Lots of us are going from fast HPDEers that would have loved to try 245s, to TT/PTers that need the soft and skinnies for points. It will be fun to watch Emilio and Andrew try the 245s in the higher classes maybe?

We're NASA racers and their classing structures reward soft compound in widths that are stamped narrow. Thus, everything of importance is won on the narrowest A6 that fits your car. The biggie for the 245/40/15 will be ST2 as that's the break point for getting dinged on lbs/hp ratio. Several guys around the country are planning a be-winged, F/I Miata on 15x10 6UL's and those made-for--ST2 A6's. I can see an ST2 Miata getting disturbingly close to GT3 cup car records set up thusly.

FYI-
American Racer has realized they don't make a tire suitable for auto-x use. At least one Modified guy is working with them to see what might work. Many of the autox world would love to not have to buy British TYRE crack and the Purple brand of crack just doesn't seem to keep up (although rumor has it those are getting an update soon). Of course this is thread drift since none of the discussed tires will be DOTs.
