I autocross. Everyone recommended Dunlop Direzza Star Specs for 18" wheels, but they don't make it for 19". Other tire I was told to get is the Hankook Ventus R-S3 (the big daddy of street summer tires by Hankook. Stay away from V10s) - which comes in staggered OEM sizes. (staggered means different tire size in front than in back).

I am ordering some today from Alex at Tirerack and should be here in a few days!

Hankook*Ventus R-S3


These tires are going to stick like glue after break-in and I don't need to modify any spacers or roll fenders or anything. Staying in stock. (Road Tire RWD class... graduating myself out of novice next time)

very nice!

Not sure you run 18 on rtr legally unless you have a base with no sports package. Not that locally anyone will care.

For ASP I think the dope setup would be 18x12 rear with 335 and 18x10.5 front with 315. Anyone running that yet?

What offset and camber setting would you be running to fit that much wheel and tire in the front? :icon14:

I've only run 345 on an 11". I think a 12" wheel would work too, but be advised that the 345 takes all the space and then some :) It rubs on the inside just a hair under lateral load. I'm not sure what the exterior "flushness" requirements are for SCCA, but it is possible that I could move the wheel out another 5mm without rubbing the fender.

I use a 10" wheel right now with a 315. The offset will need to be quite conservative, +27 to +32 with 3 to 3.5 degrees of camber. With more camber you would need a lower offset. I'm going to test fit my 10.5 +15 up front but I think that might be too much.

This stuff is way above my head. :-(

I have run Sport Package Rays and 265f/285r RE-11s in auto-x once and the car is very progressive at the limit with little to no understeer, but low speed corners need a bit of throttle to overcome the slower turn in. Grip is increased dramatically over the last time I ran auto-x with the stock RE050s.

In the ASP class there is no "flushness" requirement. Wheels of any diameter, width, and offset are permitted.
