Factory Stock front spring height

[GraceRider]

G-Body on dirt, asphalt pull-offs, stock style shocks, no spring adjusters or spacers allowed, stock engine location, 52% rear max, 3000lbs rule.

Have always ran weight jacks so a little unsure on a starting point on front spring heights. Car is a long way from ready, so calculator corner weights:

(3000 lbs No Left)
LF 713 RF 712
LR 788 RR 787
(52% rear)

(3000 lbs 52% Left)
LF 750 RF 712
LR 825 RR 750
(52% rear)

Local speed shop says LF 1100 RF 1200 and whatever height you prefer. Thinking I will start -200 from this on each side, never ran a no engine setup back class so may need to refactor. Also may try bilstein 3050 LF and 3060 RF shocks to start with using these springs?

In the past I usually measured on the front side of each spring bucket down to the top of the lower A to get a basic ride height. Maybe 2.75-3" on LF and 3.25-3.5" on RF was ballpark I think. This might equate to 10.5" spring on the LF and 11" on the RF with the corner weights above? To get 10.5 might mean trimming an 11".

Speedway advertises 5 1/5 x 12" as their best seller for stock cars? 11" LF and 12" RF seems a little tall. Any guesses? Thx.

1100-1200 was a good starting point for me both 11". I ran a 11" 1000LF and 12" 1200RF for awhile, but had to run taller springs in the back to make the rear sit higher to get the car to handle at all. Really depends how high you want the car and how much you want it to be able to roll.

9.5" tall, i would stay in the 1000-1100 depending on driver and track. I run a little lighter than that with a 3400 pound cutlass no height adjusters.

I had one that drove pretty good.

9.5" springs
1300# lf
1000# rf

The last time I messed with the G bodies we ran 800/900 with a 175/200 in the rear...seems to be the ticket for most guys up here on a flatter 1/3 mile

Looks like it could work a few ways. On hand I have 9 1/2 fronts and 13"-16" rears. Thought maybe the taller fronts were needed with the stock engine location and no spacers. This might turn out to be a fun class to run. As always some are spending big dollars, but others are relatively competitive with a low buck effort.

if you have weight jacks you use 9.5 period....

Id run a 700 lf and 650 rf based on your weights posted above.

9.5 with weight Jack's, taller with no weight Jack's or spacers
