I have a 71 chevelle and it has lifter springs in the back and is a little higher in the front than stock. (you can fit your fist between the rear tire and the quarter panel). I was wondering if this hurts the performance handling and launching-wise. I hears somewhere that the lower control arms should be parallel to the ground. Is this tue at all. I just do not want the body to roll when going around corners or have wheel-hop.

It certainly doesn't help the center of gravity any.

You have to also remember that raising or lowering a car with springs tends to increase bumpsteer.

And not to mention your roll center can go way out of whack.

I don't know about your launches but the lower the car is the better it will handle, within limitations of course. I'm sure it also has to do with shock and spring selections as far as how firm or soft they are as well as your bushings and sway bars.

It does hurt your launch also b/c the rear wants to stay in the air when you want it to go a little pushing the rear tires into the ground to help with traction. I have the raised springs in my rear end too graemlins/clonk.gif and it doesnt help much but im too lazy and poor right now to change them.
