Uneven cornerweights

I have a 1987 camaro RS V6.
Doing all suspension mods including brakes ans rear end, before I go for more power.
I have coilovers on all 4 corners.
Scaled the car, the left front and right rear is heavier.
I understand the right rear( spare tire etc.)
But the left front?

Weights
LF 944 RF 869
RR 686 RR 762
NO Driver

Heights fender lip to ground:
LF 24 5/8 RF 24 7/16
LF 26 1/8 RR 26 1/8

I could drop the LF to make it even, buy then the corner would get heavier?
Maybe because of the AC, power steering, brake booster all on that side?

This is what I have done so far.......
Coilovers 4 corners
Konis front
Spohn tube lower front arms
PA racing road race K member
Steering brace

Sub frame connectors
mofied spohn crossmember
Spohn torque arm


Rear tube lower control arms adjustable
Tube panhard rod adlustable

Magensium C5 wheels and spacers

Stabilizers bars were still connected.
Any suggestions?
Dennis

Re: Uneven cornerweights

Yeah, I wouldn't worry much about it. If you drop the LF itll lighten it but I wouldn't worry about it anyway. Once you get in the car itll be heavier on the LS anyway. and, as far as height, you're measuring to sheet metal that may not match from one side to the other, anyway. What are your plans for the car? road race, street, ...?

Yes, thanks for the input.
I was reading a thread where someone had their car scaled out and everything was even side to side, and I started thinking wow, is my car that far off?
I was just about to take it to a frame shop for verification.
I bought the car from the original owners, never damaged.
I appreciate all feedback.

Street and road race, I live out in Palm desert, the back way to San Diego has a very nice stretch of road that is very very curvy, that is where I do my debugging after each change .
I have read the weight reduction threads, a lot of ideas.

Re: Uneven cornerweights

actually, I was just re-reading your heights and weights and if you lower the LF or raise the RF to match, that'll bring those corner weights a little closer to each other. Of course, when you sit in the driver's seat, that'll lower the left side a little so, you may want to leave it where its at. For what it sounds like you're doing with the car, I don't think it'll make very much difference.

Re: Uneven cornerweights

to expand on that a little further... your cross weight (LR/RF) is about 47-48% without a driver in the car. I would guess (guessing because I haven't personally had a 3rd gen on scales) that with you in the driver's seat (guestimating with a 200lb driver), your cross weight will go up to near 49% probably. your left side weight will help the car to favor left hand corners a little better but the near 50/50 cross should help you for the right handers. with the weights you listed, the car is actually 1 lb heavier on the right side than the left. so with the driver in the car you'll be looking at probably 52-53% left side weight. pretty balanced, really!

Re: Uneven cornerweights

You could get some sand, or salt bags and duplicate your weight on driver's side.
Like AM91 says, you will loose corner weight by backing off on the adjuster. Conversely, if you tighten on the spring, you increase weight on that corner.
Once you get cross weight where you want it, you can maintain it by doing the same thing to the LF & RR, and the opposite to the RF & LR.

Re: Uneven cornerweights

On a side note-I repair and calibrate scales,including a few corner scales for racers in our area,I had a set come through that at 800 lbs,had a 11 pound difference between the pads.

That's always a possibility but I hope they're normally more accurate than that!

Most are better than that,but I've seen worse.
