Stock suspension currently, not sure I'll change suspension other than putting on a 24mm antisway bar in the rear...Seems like a lot of the aftermarket coilovers are more setup for looks than all-out performance, or at least that's my suspicion... I'm on the factory tires still, but plan to change to the Yokohama AD08R's in the nearish future (if I could just wear the stock tires out then I'd have to change!)... I'm *not* a serious racer by any means and don't plan to be, but I'd like to do some club racing events and such and I do some spirited driving as well... Oh, and I'm putting out a bit over 300WHP and 250torque... So I'm having to brake harder for corners when I'm doing my spirited driving... ;-)
