I had them on my 04 GT, with isolators and no coils cut. It was roughly 3/4 - 1" all around drop. The rear was a tad higher which I liked for a little rake effect.
i'll try posting here. the front is 1" higher than the rear, if I cut the fronts do I cut from the top or the bottom, or will pulling out top and bottom isolators drop the front 1"?
