There are several 18" choices in the 18lb range, if weight is a concern.
Plus would you really want to increase your sidewall height? (unless running 1/4mile )

There are many 17s that fit all around. With a stiffer sidewall characteristic to most high performance tires, going up one size in aspect ratio isn't going to make a huge difference on turn in, may roll over a little bit more, but the 17" tires are so much cheaper anyway...
