The car I have is a 1974 chevelle malibu with a 400 pontiac motor. The suspension I have underneath it has been completely done with junkyard parts. The front right is a stiffer than stock spring, and the rear left is a stiffer than stock spring. My problem is that on a dry slick track, I have a push in the corners, but if its tacky, it sticks just fine. Should I put a little bit of shim on the spring on the right rear to make it stiffer? Where should I change my stagger? Any help would greatly be appreciated.

I do have a "weight jack" device on the rear, so on dry slick should i give the right rear a little more spring?

The car hasnt been scaled, and I dont really intend to scale it since it handles so good. The push on an extremely dry slick track is the only trouble I have had. If I spun the right rear weight jack down 1/2 inch, would that be too much, or not enough? Or will I just have to experiment? Thanks for all your help!

that would be a good start anyway just be sure it's the car and not the right foot making the push.what are the front and rear springs out of?

The front left spring is stock chevelle. The front right spring is off of a 1/2 ton chevy van, and it has a 3/4 inch spacer on top of it. It is porbably comparable to a 1200 lb racing spring. The right rear is stock chevelle, and the left rear is off of an old pontiac bonneville. It is about an inch and a half taller than the stock spring, and a little bit bigger in diameter. The car handles great! Just this push problem...

does the left rear sit higher the the right that might be your problem it's putting to much weight on the rf we ran vega springs on the back of our 75 malibu

Pit Bull when I first got into racing I use to use stock springs and everything for the salvage yard. The best set up I have found was a 3 quarter ton front Ford truck spring(you'll have to cut it down to what you need). Find the biggest heaviest station wagon like the old Olds wagons and put them on the rear. We played with different size tires. Like a 225/70/15 rf a 215 or 225 70/14 lf pretty even on the back. Both 15's don't remember the exact size since it was about 10 years ago.

Yeah it does sit a little higher on the rear left than the rear right. Should I try to correct that with the weight jacks? I have about 1 1/4 inch of stagger on the rear (smaller tire on the inside) By the way we run 60 series IMCA Mcreary tires. Im thinking about adding about 1/2 inch to the right rear each time there is a dry slick track, because on a tacky track this car handles really well. Any other suggestions?

you could try the jack i think pickel has a idea for ya 3/4 ton sping on the front soft fronts will sometime cause a push we always ran those fronts

I dont think that the front right is too soft - it is actually really stiff. However, I did install a larger front swaybar. Was that a mistake? Could this cause a push?

I ran a 75 Malibu for 2 years and I've always had problems with it handling right.
I tried everything i could legally. I took all the weight off that i could and nothing helped. My car seemed to be to long and heavy for my liking. I dont believe changing sway bars will help you either. Have you tried running without one?
