What rear suspension for bracket racing.

I commented before the o.p. posted his goals, 13s at 6000 feet. Now, assuming he might one day run his car at 500 feet, and that it might run low twelves at that point, i think slicks, good shocks, and ss springs will easily get the job done. If he wants to spend more, for more performance anticipated down the road..... caltracs (or assasins, like those too) or ladders. More work, and more money than neccessary for op's goals.
