I don't think you give the 6 enough credit. It has plenty of National Championships and trophies in STOCK form in stock class in the SCCA. (I ought to know, I won one the most recent of them) It's kinda like racing the 944. It leans a lot, but still sticks. The money from Mazda was nice though.
BTW, my Stock Class MX6 did a sustained 1.03 G with a peak of 1.10 at the Wendover Pro-Solo this year. I've raced plenty of other cars and actually think that the 6 is faster through sweepers and slower through transitions. (Damn those Mini's!)
"Drifting" or in the case of a FWD car "snap oversteer" is the slow way around a track. However,
it is the fun way.

Every time I do it I come off with a BIG grin.
Oh well, give the 6 some credit, there is a reason it has 5 National championships in SCCA Stock Class and the Probe has none. (And plenty of people have tried in the Probe)
