I have a pretty bad push that I can get rid of by goosing the gas about 1/4 way thru the corner but I'd like it to not push period. Every picture of my car that I've seen shows me turning left all the time.

Scale numbers...

Rear: 46.5%
Left: 54.0%
Cross: 49.0%

Total weight: 3011

Metric Monte Carlo with No weight jacks.

Springs: LF 950 RF 1000 LR 200 RR 200

Stagger: 1" on both front and rear

Shocks are all 50/50 Pro Shocks.

Rear suspension is: Stock Lowers with 3rd link and panhard bar.

Any suggestions?

I've got about $200 bucks in the ole racing budget right now so I could probably spend that on different springs, different tire (stagger) or maybe even shocks. One thing, but not all of them.

I went from a 175 LR to a 250 and it made a severe push turn it a loose condition off the turn.

try going to a 1150 on the rf and put some more stsgger on the front. if you can change offsets too that might help by putting a big offset wheel on the rf

WesternAuto: I was thinking of going to a 225 or 250 on the LR. You made a 75 lb. change (175 to 250) and it looks like it made a drastic difference especially coming off. I'm pretty happy with corner exit now but I've got to get thru the corners without sliding up the track. Think a 25 or 50 lb. change would make enough difference for me without getting way loose on exit?

Racer17j: I still get a bit confused when talking about wheel offsets. By putting a big offset on the RF do you mean "sticking that wheel out", or "sucking that wheel in"?

I don't know exactly what front stagger does but like everyone, I have an opinion. In my mind, front stagger is simply a tool that will change your ride heights on the front. Because the front suspension is independent, there really isn't a way for the circumfrence of the LF tire to effect the RF the way it does with rear stagger. Here's what I think would happen (I don't have a taller tire to test this) On the scales, a taller RF would tranfer weight to the LR just like raising the ride height on the RF. Is that the effect your looking for by putting on a bigger RF tire?

stonewall,
you are right. front stagger will change the ride height..anytime you change ride height, cross-weight will be changed.

yes sticking it out further will help and like ac said it will add cross weight to that corner with a taller tire i run 2in min stager on the front up to 4 inches max and run even up to 2 inches on the rears i tried 3 inches on the rear last week and blew what could have been my first feature win because it made me way loose and the rear end just went right out from under me in the first turn. i'll give you fair warning if you are going to buy a new wheel make sure they state if the are talking about back space or offset you will want a 2 in back space or a 4 inch offset it just depends on who you buy it from it's the same thing tho

I went from 1125 on the RF to a 1200 and it helped the loose-off a ton. I had to give up a little at the other end of the track, but stiffening the RF definetly helped. Next, I'm bumping the LF up from 900 to 1000 to see what that does.

Well I run a lf 1000 lr 250 rf 1200 rr 200. I run 255/70/15 all the way around the car, on the left rear i run a 2" offset wheel. My car has never been scaled of anything I dont know my cross weight but my car runs awful good at both tracks i run. Oh yeah I also use the heaviest stock shocks I COULD find... I'd try a new set of heavier springs. Midwest motorsports where I get my front springs there $60.00 a pieace....

Thanks for all your help & the car WAS running good till someone spun a few cars ahead of me on the backstretch and as I went to make a pass, I slammed right into him, then got slammed in the rear. Now instead of better handling parts, I have to spend my money on replacement parts & straightening the frame. I wrecked hard

Hey Sonewall,
you have 46.5% rear, what if you had more rear weight? Like 50-52%, then you could steer the car with the throttle/brake and there wouldn't be much of a push left to deal with.
All your weight up front is pushing out/up, which is why you are turning left all the time.
Just my opinion.
