Doug, the gears are the stock 3.55's and the tires are 28" in the back and 26" in the front. There are zero choices for our cars in the front, unless you want to run run bias ply (been there, done that, got the underwear stains to prove it!), so a 185/55-17 is it. I've been running this same combination for years with no issues, so I'm chalking it up to me having to disconnect the battery on the previous runs to get the car to shut off. I think the ABS system needed to relearn some parameters and I should have driven the car before taking it down the track. I had the car over 120 a few times on the way home with no issues, and did a few panic stops from 75-80 just to be sure. By the way, the Hawk HP Plus brake pads are worth the money. No fade and no dust!
