I haven't drove my car in a while, but when I did, I was loose from center off.
I believe it was on the throttle loose.
1980 Cultass Street Stock
Scale numbers (with Driver)
RF 820
LF 860
RR 780
LR 1004
Total weight 3464 (minumum 3200)
Cross 52.66%
Left 53.81%
Rear 51.50%
Left Bite 224#

Ride Heights
LF 6-3/4" RF 8"
LR 7-1/2" RR 8-1/2"

Stagger
2-1/4" Front
1" Rear

I'm thinking I need to pull a spacer out of the RF, 8" I think is just to high.
I also should pull a spacer out of the RR.
But Pulling one out of each will not help lower my cross of left rear (which I believe need to be lower).
Is my thinking correct?
I need to lower the left rear weight to prevent throttle loose off, Correct?

i'm not sure about the ride height issues for the gm cars (mopar guy) but i would think lowering the right side might help. it would help lower your cross and left rear bite. i only run about 120 lbs of LR bite. another thing you could try is running without any front stagger or at least adjust it to an inch or lower. that will lower your cross which should help the loose condition.

Hopefully I'll get time tonight to work on it.
But i'm thinking lower RF to 7-1/2", and RR to 8".
Then I'll have to rescale it, while on scales I can put a bigger LF tire on it also.

Don't lower the RF, RAISE the left front. The metric chassis need to run a higher ride height to keep the front geometry within a "livable" perameter.

Let me get this right
More spring spacer's or taller tire will get more scale weight on that tire.

I raised the LF a 1/4", and installed a 1-1/4" inch larger tire. Cross weight didn't changed much.
To lower cross raise LF or RR, or remove weight front the RF or LR, correct?

bigger l/f tire will hurt your entry. you want your r/f 1in higher than the left.

my metric ride heights were
l/f 7.5 r/f 8.5
l/r 8.5 r/r 9.0

front tires get you in on stagger. stagger on rear help you off..

my guess would be way to much l/s bite
