a *lot* longer, and they aren't as finicky. Hoosiers will go off quickly,
and Kumhos are more durable. I have driven both of them to and
from events, and I have gotten flats with Hoosiers, but not with
Kumhos. It may be that if you are a very meticulous autocrosser
with race-only wheels and tires for at-the-event-only, and you
know how to set up for a given tire, you might possibly get an edge
with Hoosiers, but if you're at all looser than that, Kumhos will give
you a lot less grief, and won't hurt your times. I won the S.F. region
'06 series on Kumhos.

Road Atlanta has a auto-x that is an actual course not cones. They use it for big events like the year one experience and lots of people show up every year to see what their cars can do on the auto-x and the big track and they were taking the panoz race cars over there (before skip barber took over 
) and allowing race school students to set laps. I ran a 22.6 I think, I cant remember, but it was the fastest lap on the course when I ran it. I couldnt match it though because I was on hoosiers and they kept making us park in a dirt parking lot between runs, so my tires were cold and dirty. Then I blew a radiator hose and had to call it quits.

Hi Al. I find the 710s to be just as fast as Hoosiers and they last
a *lot* longer, and they aren't as finicky. Hoosiers will go off quickly,
and Kumhos are more durable. I have driven both of them to and
from events, and I have gotten flats with Hoosiers, but not with
Kumhos. It may be that if you are a very meticulous autocrosser
with race-only wheels and tires for at-the-event-only, and you
know how to set up for a given tire, you might possibly get an edge
with Hoosiers, but if you're at all looser than that, Kumhos will give
you a lot less grief, and won't hurt your times. I won the S.F. region

Thanks for that info Joe, I'll definitely keep those in mind.
Al, buy a set so I can test em, and I'll get the A6.

Thanks, I actually like it much more than the typical auto-x because instead of one long lap, you get 3 laps on a shorter circuit. It is addicting, but I like the big track better, especially ours.

Make sure you have the PSM off. Since you are just getting into ax, it may take a few trips out for you to get a feel for it. Not trying to diss, but in racing it's all about the driver. I know because I've gone against other stock TTs and got a good beat down.

OneTime Make a point I forgot. There is no PSM system that could simultaneously
protect the average driver from danger and allow the car to be as loose as it has
to be for good autocross. Absolutely turn it off unless you're running in standing
water with slicks. PSM will shut the power off in slaloms. It will interrupt you like
a lawyer tapping your shoulder while you're trying to have sex. It adds a second
per lap even when you don't notice it.

Joe,
I went to the Kumho website this morning and I can't find a tire combination that will be safe for AWD in 18". The 245's and 285's are 24.8" tall. The 315 is 26.4 and the 345 (which is probably too big for my car) is 26.8. I think that is too much of a spread for the viscous coupling.

the tt would definitely not my first choice...too heavy. Had an S2000 that was slightly modded which was the best car for these short events. Depending on how much you drive it on the street, just be careful how much neg camber you dial in...optimizing for autox will murder the life of your street tires!

tar6day,
RWD might be OK if autocross is all he plans to do, but I don't think it would be good in high-speed events for an inexperienced driver.
Dez,
There is too much diameter difference between those 2 tires. The 315 is over 6% taller than the 245.
Joe,
I think that might be a good combination for autocross on stock width wheels. I was thinking in terms of what would work on my wheels and that's not the theme of this thread.

Ok, this thread doesn't describe your wheel sizes... Hoosier and Kumho
are the top autocross performers, and you do need the diameters close,
and if there's any difference, you'd want the fronts taller, not the back.

why do you want the fronts taller than the rears?
also what is the best alignment settings? I've seen some that say that the rear should have more neg. camber than the fronts and some say the fronts should have more neg. camber than the rears? Which is it?
