What rear suspension for bracket racing.

13’s 12’s upper 11’s I’ll second the Double Adjustable shocks. Long term investment. An adjustable snubber, thats cheap and can resell at a later date if you exceed the limits of what you have. Work on finding what it takes for hooking, the weight transfer etc. Drag radials with dialed in psi, obviously. No need for chassis re-engineering at that level, at all. If you don’t intend on making the type of power to get you into mid-low 11’s and quicker then I wouldn’t bother with re-engineering things. Increasing power, going quicker and Faster, a more serious effort and building on the tuning experience, setting up the factory style suspension you may one day exceed things and naturally have to gravitate to those modern components. Shocks and snubber for now. Cheapest and a good start. That’s my .02:)
