What rear suspension for bracket racing.

Well this is what i did Your mileage may differ:p

20 sec, stock pizza cutting tires(all stock with 2.76 gears)
down to 17 sec, gear change to 3.23
16 sec, replaced 318 for a 340 and a set of 3.55 gears.
15 sec, hopped up 340, clamped front segment of stock leaf spring and added cheater slick.
14 sec, add of real slicks 26/10/15...... car got to low and started to rub on slicks(Front segment of spring was bending behind my now, 3 clamped, front segment stock leaf spring)
low 14 sec car with SS Springs,2800 stall converter and 4.56 gears.
------------------------------------------------------
The rest are 1/8 mile so you will have to get out the slide ruler to convert to 1/4
8.30 sec car with Better heads,12.8 compression 408. still 2800 stall that now stall at 3000 and same 4.56 gears
A best of 7.76 sec.........With a real 4200 stall converter,but traction problem and ET keep getting slower.........
New bigger slick (26/10/15 to a 28/10.5/15) traction improved but not consistent and not to the level of above.

My go pro showed me that my SS Spring were shot.
New SS Spring and times improved, but not to my best (7.76) runs in the 7.90.
I'm now having to learn how to get the most out of my SS Spring.

The moral of the story???????
You don't have to know a thing about tuning a chassis with a set of SS Spring, and they bolt up just like your stock spring(on a A Body)
Caltrac's You need to adj it to make it work......................
Latter bar,You need to adj it to make it work...................... or some on who knows need to set it up.
4 link.......Probably the best and most adj ability but you need years messing with it or someone that knows the in and out of it. To help you through/out with it.
You need to know a hole lot about setting up a chassis to make it work right.

WOULD I CHANGE ANYTHING, IF I HAD TO DO IT OVER..........
Living in the same money restraints........Probably not
No i take it back, i would not have relocated my SS Spring inward to gain clearance for the bigger slick. I would have bought a fresh set of the smaller slick and tuned the chassis to make them work. Aka what i'm doing with the bigger slicks.
