I have determined that I DO have Gymkhana suspension. I have replaced all bushing, bearings, and ball joints, but did not replace springs.  I have taken maybe 50lbs off the front end with some modifications and now I hate the way my car looks.  Very high in the front end. Looks like a C3 4X4.  I thinks the Gymkhana springs are harder springs and Im unsure the best way to solve the problem.  Would stock springs lower the front end? Should I cut off the Gymkhana springs?  How do I know how much the car will lower by using softer springs?  Is there some method or formula or is this a trial and error job????

Unfortunately, it is a trial and error deal, especially since you don't have the same springs as others who have cut theirs.  Take out the spring and use a cut off wheel to remove maybe a half coil.  Put it all together, drive it around a bit, and look at it.  Repeat as many times as necessary.  You could use softer springs, but that would undo the benefit of the gymkhana suspension.

You might check with Vette Brakes&Products, VBandP.com, 800-237-9991.
I installed their Grand Touring Plus advanced touring system, in my 1979. It came with new front coil springs amoung other parts. I must say I like the change and the new coils did lower the front a but, without changing the ride quality.

Just a thought...double check that you have the springs installed so that they are not sitting up on the noches in the sockets in the control arms, I have spent many hours readjusting the springs so that they sit perfectly in the sockets and have even rotated them over to have them lower the front...Speeddirect.com now offers adjustable coil overs...both the coil over and the shock is adjustable for height and ride control, haven't tried a set yet but will in the spring.
