Just scaled the car after putting it back together.This is what it came out to be.left-53.1 rear 49.7 cross 49.8 last year it was 53.5 left 47.8 rear 49.5 cross. What would I expect to be different about this years set up so far.Car was good last year.total weight is 3064 w/driver last year it was 3221 .What are the ranges of percentages that I should be shooting for?

I just got my car scaled this weekend. Being new to dirt track racing, I barely know what the numbers mean, but certainly don't know what I should have been looking for.

Left - 52.1%
Rear - 48.8%
Cross - 49.9%

The car scaled similar to last year but these are some of the changes made.front springs l 800 r 1000 last year l 1000 r 1100 this year, rear springs are the same.gastank was moved towards the center and I chopped about 160 off the weight.The area I was wondering about was when the frame was straightened they must have ended up alittle lower by the springs and control arm mounts than before .i was running 6 3/4 ride height lf 7" rf 7" lr and 7 3/4 rr.This year its 7 1/4 lf 7"rf 7"lr and 7 3/4 rr .the big difference I see is the ride height on the lf ,what is a more reliable measurment the scaling or should I try to get the ride height where it was.

Daddy, why would the car be looser with more rear %?

i dont know if id condem the frame straightening when you changed front spring rates and put car on diet. as far as changes youd expect to feel id think car will be tighter due to increase in rear percentage and all else is close to the same but the way you ride heights are written seems odd and i dont think your gonna like the front springs that way too soft but just my 2 cent worth about .5 cent good luck im probably way off.

I agree. On a real heavy track I have always took some weight off the rear to loosen it up. Put it back for a dry track to tighten it up.
