What kind of tires is everyone (maybe all of 5 on this site) using that takes their car to roadcourse, high speed autox stuff. I'm looking into some stickier rubber for this year. I'm torn between toyo ra-1 and kuhmo mx. I drive the car on a regular basis in the summer, so I need something that will do ok in an occasional rain, which is why I'm leaning more towards the mx. Anyways, thoughts, opinions? TIA-Garrett
