In your opinion which one is the best for running 18" wheels? Ride Quality, tire rub, ground clearance, and another info that I may need!

Hello
I would suggest going with the Pro Kit! (1-1.25) The Sport lines(1.5-1.75) really drop it and that will eliminate a lot of your ground clearance! Another suggestion would be no matter what set you get a adjustable pan hard bar would be a really good idea to allow you to recenter the rear end back under the vehicle due to the rear ends shift when they are lowered. Below is a link to show you what all UMI Performance has to offer!

If you have any other questions feel free to ask and I will be more than glad to help!
Thanks

I went with the Pro-kit springs. The car lowered about an inch or so. I think any lower than that and you may run into problems. As for the adjustable panhard bar, trust me you will need it. I had my car spin out on me because of the axle not being centered/shifting. I'll be runing 18's in the rear and can post pics once I get them on. Here's a pic of my car before and after the drop.

i find it funny that my car sat higher when i had sportlines then every other car i've see with the prokit.

But yea, i vote for the prokit as well, the sportlines rear springs are too soft and too short. For looks only, not really good for spirited driving.
