thanks for info manga and red celica...I thought losing an inch in wheel size and then adding just
5-10mm in tire profile..I had no idea this would make my tire/wheel combo diameter larger
than 18" setup!

Hahaha! Sorry man, couldn't resist.

And your right, I spend way too much time on S2ki over the years. They should give me some kind of stock options.

But seriously, have you checked the muffler bearings yet at least?

 

I am sure the tiers and wheels do weigh less in the 17". If the 17" tires are actually taller diameter that is probably the issue. The offset would not cause anything you are feeling.
