Cal Club Autocross Forums

Although I am not ready to purchase tires yet wanted to start the research. I am running a 1990 C4 Corvette Z51 6sp in BSP. What would be the best tires for this car which would allow me to stay in BSP.

Thanks in advance for your input.

Not quite as fast as the Hoosier, but a bit less expensive and you'll get more runs out of them. They also don't require quite as much negative camber.

You'll want two sets of racing wheels. After about 50, 60 runs your first set will become your practice set and you'll want to have a fresh set for the races. Quite a few folks drive to our events on their 710's ... something you typically wouldn't want to do with the thinner Hoosiers. Buy a tire plugging kit and a spray bottle of tire filler. Virtually no garage will fix a Kumho/Hoosier flat tire.

Seems like most folks here don't believe in having your tires Heat Cycled: http://www.tirerack.com/tires/tiretech/ ... ?techid=66 For the price, I personally feel it's worth it.

We found that camber optimal settings between kumho and hoosiers to be nearly identical, camber limitations are usually a Stock class problem anyway.

I am with "most folks", for autocross don't heat cycle your tires.

Going back to the Brian Peter's "oem" camber settings today ... although HE did agree it was worth trying less camber with the 710's, since "his" car/setting's were understeering at CA Speedway (see his relatively poor PAX the weekend he delivered the Z06)
