front to rear weight percentage

gnicholson · 08-05-2017, 10:23 PM

i recently scaled my friends super stock automatic smallblock 68 camaro .with him it weighs 3160 . its allmost 200 lbs front heavy and with no preload in the 4 link its right at 100 lbs heavy on the left rear. the car doesnt pitch rotate enough but does launch straight. any thoughts on these numbers?

Most cars like between 30 and 60 lbs. of preload (Right rear heavier than Left rear).

Make sure and check the preload with the driver, fuel, and tire pressures in race mode.

thats what i thought. with no preload at race weight it is 100 lbs light on the right rear compared with the left. seems like i would have to add a ton of preload to get those numbers plus all the lean it would cause. maybe better to add a half inch to the left front
. It also seems like it has too much front end weight I realize with a 4-link and shocks I should still be able to tune the car but just static weight-wise I think it's too heavy in the front and was curious as to what some of you guys with some experience on these cars would have to say about that

For what its worth on my Monte I was 52 percent nose and 80 lb. lighter on right side rear. I tried getting weight equal on rear but car would drive right in wheelie. Your 53 percent nose heavy may only be a little heavy and my thought was to fast of a pitch rotate and not drive into wheelie would be slower to 330, but I was never really fast weighing over 3500 but could 60 ft. 1.27 so take it for what its worth. But being lighter on right rear was never a problem for me.
