    4 link Q!!

    i have a 1974 vega and it does a outstanding wheel stand when it leave"s. it has a four link. if i drop the top bar down will that take that out of it? i want the shoot down the track effect instead of wheelstanding. i think that will improve the et.

    I believe it will make it hit the tires Harder...I don't run a 4-link I use ladder bars but the principle should still be the same.

    Down on the back at the rear end or down in the front where it hooks to the car? I am no chassis guy but I doubt it is as simple as that...meaning I think it is gona depend on your whole set up how it will effect it. JMO

    You really need to look at the overall setup as in weight, HP, center of gravity, instant center, shocks, spring rates ect. If your overall setup is right then raising the top bar up in the front or dropping it in the rear will take some of the wheelie out of it.

    While wheel stands are not good for steering, if they come down softly and don't compress the front suspension they don't hurt as much as some think. The problems come when you have to lift because of control problems or transferring weight from rear to front setting it down. This can unload rear causing loss of traction.

    The cure. There is a balance of Center of gravity, Power and traction. These are the things that make wheel stands or not. While instant centers can effect traction some, it is usually not going to be the sole fix. More power needs more traction and lower, more forward COG to keep front under control and go fast. Giving up traction or power will keep front down, but it's not fast. This is the simple magic of a good working car. If you get the balance right, it makes you look like a wizard on suspension set up. As cars get faster, they get longer and lower and this is why. When you get tired of star gazing, move anything you can lower and forward. Especially lower.

    You need to scale the car and see what the corner weights are. Just a simple spring adjustment or pre-load adjustment might take care of it. But you need to no what each wheel weight is.
