I would like to lower it and maybe go up a little in the tires. I was worried about going with the low profile tires and losing the smooth ride but i took the plunge anyway and to my surprise there wasnt much difference in ride quality. I can feel the hardness of the tire but its very minimal. Plus i really only drive it on the weekends. Its not 4x4 and as far as going big and up, thats what my jeeps for.
