We've been screwed lately by the SCCA autocross classing, teasing us with a possible move to a competitive stock class and then ultimately leaving us in with the Boxsters and S2000's. It looks like they have finally thrown us a bone. The class is called STX and is a new Street Touring class. This means street tires (min. 140 tread wear rating) no bigger than 225 series on a 7.5" rim. Suspension mods are pretty open, allowing springs, shocks, sway bars, etc., even coil-overs. Cat-back exhaust and a chip. No cam gears. Pretty close to J-stock, actually. Anyway, it allows sedans up to 2000cc turbo's (no boost changes allowed) and normally aspirated sedans up to 5100cc. E36 & E46 M3's and all M5's are specifically disallowed. General consensus is that the E30 M3, WRX, and Integra Type-R are going to be the hot ticket cars here. Mustangs are probably killed by the 225 series tire rule.
I'm seriously considering running the M3 in this class next year, but I need some input from the collective wisdom as far as my new suspension is concerned. The M3 is still going to be my daily driver, so I need to make a bit of a compromise here. What do people like for a compromise set-up that's good for the track and autocross, but still livable on the street? I realize this is very subjective, but as this group is so good at self-policing : -) I'm sure your input will be helpful. Thanks,
