I have seventeen's and put the h&r sports on mine(lowering kit) and I have stock suspension because I like the feel. You will corner 100% better and be able to steer better as well. But an alignment is needed. I put my springs on at my dealership and went from my service bay straight to the alignment rack and had to adjust a little toe and I still have to oval the strut on the right side to adjust the camber. It wasn't a huge difference? But it'll eat tires.
