Tire fitment?
 

I'm wanting to get the Cobra Jet Drag Springs from Americanmuscle.com. It's a 2" drop in the front and a 1" drop in the rear, but I also want to get new wheels, front is going to be 19x8.5 Niche Apex with 255/35/19's and rear is going to be 19x11 Niche Apex with 305/30/19's. I know they should fit stock height, but I don't know if lowering it would affect it, and if so how much? Not sure if anyone has done anything similar to theirs on here or not. I've also heard about doing something with the sway-bar links, I believe shaving them down or something.
