[Colonial Cobra]

Go with the 17's.
I have had both on mine and there is no comparison.
I thought it handled good and launched great until I bolted on the new ones. Totally different car. Handles like its on rails, much quicker off the line.
I lowered the car an inch to make up for the difference in tire heights. And the ride is only a bit harsher.
You wont be dissapointed.
