[Shotimes] advice on autocross handling

[Don McKinnon (AST)]

IMHO, I can see it happening.  If the rear CC springs have a high rate (compared to stock), coupled
with the 26mm rear bar and delrin bushings that is going to do weight transfer on the rear outside
tire well before that progressive sprung front with rubber on the ASB.   With the front will be
slower to react than the rear, oversteering can be happening on the initial transition when hitting
the tight turns.  Maybe on big sweepers this would not be such an issue, but quick tight turns yes.

Joseph,

This will sound like a dumb question, but are SURE it's oversteering too
much?  There have been guys who have tried all sorts of things to get the
SHO to oversteer for Auto-X, going as far as disconnecting the front sway
bar entirely.  I honestly can't see how your car could be so bad.  Maybe
it's something that just needs getting used to?
