Lowering springs, where did I go wrong?
I have a 2004 Mach 1. I wanted about a 1" drop, nothing drastic. I did my research, so I thought, and decided on the Ford Performance M-5300-C springs.
According to several websites the estimated drop for 99-04 mustangs is 1-1/8" in front. I found reviews that said on a Mach 1 the drop was about 1". Perfect! I just completed installing the BBK caster camber plates with the BBK isolators and the M-5300-C springs, fronts only. I am only seeing about 1/2" drop. I'd be happy with a 3/4" drop but, only 1/2". What did I miss? I am hesitant to install the rears because I don't want the rear end to be lower than the front.

Re: Lowering springs, where did I go wrong?
The Mach 1s were lower than GTs from the factory, so non-Mach 1 figures wouldn't apply.

Re: Lowering springs, where did I go wrong?
Are the bbk isolators thicker than stock? Are you sure the pigtails of the springs are seated correctly?

Re: Lowering springs, where did I go wrong?
You used poly urethane isolators. They're thicker than factory rubber and also don't compress at all. Put the factory isolators in and it ought to come down some.

Re: Lowering springs, where did I go wrong?
Thanks for the options. I'll make sure everything is seated correctly. My oem isolators are in still in good shape I'll try them also.
