Suspension

A few months back I finally got my car here on base from out of state. I had a Steeda 5-lug conversion kit put in and I swaped out to 17X8 Eddelbrock 454 wheels. The set up looks great but now my tires rub the fenders when I go over big bumps. I relized that I need a new suspension set-up. My ultimate goal is to imitate the SVO car in terms of suspention and performance. First off, I think the coil springs are shot. The car has 230,000 miles on all original undercariage. It seems to sit lower than it should in terms of factory set-up. I'd like to go with the UPR K-member with coil-overs. Is a K-member a good idea?Since the 1965 Shelby GT-350, SVO, and Saleen Mustangs had Koni shocks, I decided to get some myself. Does anybody know what sort of Koni system I should get? I think the SVO had quad shocks in the back. How does that work? Koni sells a SVO Mustang kit on their site, but will it fit my 1991 N/A 2.3L? Will it work with a K-member? Help!!

I can't say for certain how much it cost as I was away and had my dad do it using my funds. The kit was about $600. All in all, it cost about $4,000 for the kit, its instalation, for the wheels and tires, with all labor. A bit more than I anticipated, but I was committed. I think it was worth it, Edelbrock 454's man! But anyway, the kit required the spindles and struts from a 5.0, so it has that.
