If you really want to do things right, I'd suggest considering the TC Kline dampers with a set of springs. The TCKR dampers aren't shiny and full of bling like all the coilover units, but are valved specifically for T2 competition and have a wide variety of adjustment (both bound and rebound). To compliment them, you can find a spring equivalent to the T2 spring, both Hypercoil and Eibach should offer similar size / rates for the TC Kline application.
