Grand touring suspension height problems ?
I installed the grand touring suspension from VBP this winter and I am having problems with the front end being too high. I have the 460 coils and the 330 fiberglass rear spring. The ride height in the rear is good at about 27 3/4 inches and the front is about 29 inches . If I raised the rear a little would that bring the front end down ?? As it is the front looks too high . Or will I have to go to the extent of cutting the coils? If so how much coil do I remove to drop about an inch and a half ? Brent

same problem that I had with the 460s.... have a look at my gallery, the photos with the 29" ride height are somewhere on page 2 or 3.... I cut the springs, then I was unhappy with the ride comfort (softness) and got 550s and Bilstein shocks.... those photos are in the gallery as well....
And no, before you ask... these will not sag ... it will stay at 29".... been there, done that and was upset that I had to re-do the front twice to get it right.....

Raising the rear will lower the front - but only a small fraction of the
amount the rear goes up.
So, that is not the solution to your problem.
Before cutting or swapping springs, make sure the end of the
top coil is seated properly in the top pocket. If so, then cut or swap.

Been there done that, only way I could get mine down was to cut one coil off the 460. Wish I had goine 3/4 coil now but I can live with it the way it is now. Pictures of before and after are on this link.

I've installed their spring before but never had that problem. Make sure that the springs are seated correctly. Also when you install the spring you have to loosen the 2 bolts on all 4 of the a-arms and leave them loose until the car settles. A trip around the block should do it. Than go back and tighten all the bolts up again. These bolts are right at the bushings and when you loosen them, just back them off a couple a threads so the lock washers are not compressed. If you don't do this you will wear your bushings out twice as fast.

460 lb Coil Springs
The VBP 460 lb/in Coils are turned from our specs and should hold your car at or even slightly below stock ride height. The 550s will lower the car about 1-1.125". Like the above posts, make sure the springs are seated in the control arm pockets properly and everything should be fine ...

I agree on the 550lbs springs - these are great. The 460lbs springs however require a coil to be cut off, I installed the 460s several times (took them out, made sure they're seated correctly, re-installed, removed, cut, re-installed) ... please see this thread:
