I want to give my 89' GTU an agressive stance, and more rubber on the back. So, I had the thought to put 17's on the back, and 16's on the front. Match the profile on the drive tires to the outer diameter of the stock wheel/tire combo ( So the speedo stays accurate ) and run the same profile up front.

The question is, how will this effect my suspension? Will it mess up the weight distro or something? ( less than a 4 pound difference between the 2 16's and the 2 17's ) Thanks for your comments.
