im looking at gettin the prokit, (1.3" lower) and i just got 18x9.5 wheels with 275/35's. u guys think ill be ok with no rubbing?

 

What is the offset of the rims?
You should be fine. Feel with your hand around the front of the tire, right above the lca. The area where the inside of the tire would hit the front of the wheel well. This is where your going to run into issues.
If it hits or there is very little clearnece you can just pick up some 1/4 inch spacers. Or pound out the wheel well. Some people dont like taking a hammer to their car. I could care less, after what this dam car has put me through, it deserves a beating.

 

i'm running 275x35x18's out back with a 1.75 inch drop. I used K-sport springs (love them, and they are a good price) and haven't had any issues. however, i couldn't recommend riding anybody in the back seat lol
