Thanks for the reply guys. John, as you've noted, the SVT is not going to be very competitive in GS. I'm looking more toward Street Touring or maybe a prepared class. I love the car and would love to find a niche for it.
On the lower profile issue...there isn't one. Tire Rack's listing shows the same profiles for 15" and 16" tires. Therefore the 15" will be slightly shorter. Every little bit helps. Thanks again.
