I'd highly recommend looking into the Pfadt Sport Shocks and Sway bars. I've been running their shocks and front sway bar on my Super Stock C5Z this year with pretty good success (won the Toledo ProSolo on 80 run tires). The sway bars are highly adjustable unlike the T1 sway bars. I'd say that the T1 front bar is probably too stiff for an autocross car. The new sport shocks perform on a level far above their price point. Aaron and Co. at Pfadt hit the nail square on the head with these shocks. You can't go faster for the $$.
