mine only rubbed on the rear pass tire! but i actually thought it was a better ride with the sportlines then the stock svt but you do feel the bumps alot more and are going to want to get some better shocks to go with the springs.
if i still had that one i would offer you a ride in it but i have the stock svt suspension now and im almost set on getting a speed 6 this summer so i wont be dropping my car in the spring.
I had pro-kits for awhile, ride was nearly identical to stock only slightly firmer. Tires never once rubbed with that. I have sportlines now and it's very firm and does rub alittle. Lol. You will definitely need an alignment afterwards!
Moved to wheels, tires, brakes and suspension chat
I have the complete Pro-kit drop, 1.5" springs and shocks/dampers. I drive my car 70 miles 4 days a week and I love the pro-kit on a daily driver. It is much firmer than my stock sedan suspension, but not at all jarring over bumps. It also handles like a dream, especially after I installed a 22m rear sway.
Here's a pic of the pro-kit 1.5" on my sedan, its a tiny bit lower in the rear due to two 12" subs in the trunk...
