I run 1” overarch rear springs with the rear bands cut off, which is too much rear spring. I run QA1 double adjustable rear shocks and QA1 R’s single in the front with / 6 bars. No sway bars, no snubber, 4.10 gear, converter flashes to 3340 according to logger. There is nothing in that setup that makes the car unfriendly for the street for me. The setting on the shocks would need adjusting to make the street driving pleasant, but that is just a twist of a knob. It’s best 60’ 1.68 on an F70-14 6” wide tire. The point, there is nothing really exotic suspension wise needed to launch your car. I ran 1.74 60’ with the stock 340 bars and the 340 front sway bar and KYB gas shocks on the F70-14 redline. Super stock springs are very stiff and with the shorter front segment increases the % of rise. Great for a big slick car that transfers weight well, which you can hammer as hard as you want. I have never run ss springs, but I never shock the tire, so they are not tailored to my style of racing. In my style you just want spring enough to hold the rear of the car up and not bend the front segment. Then control the axle with the shock.
