I lost count of how many times I've read a post about the new eight speed automatic in the Corvette and some Cadillacs, due to disappointment in the claim that it shifts as fast or faster than Porsche's PDK. I didn't doubt GM's claim when I read it but I lost faith after all the disappointment. After seeing this video, though, I'm starting to regain trust in GM's claim. I think the trouble is that people are expecting it to act like a PDK or a good double clutch transmission all the time and I don't think GM intended that. I think GM wants it to act like a traditional torque converter automatic - slower and smoother - unless you're flat out and that's where the frustration comes from. If you keep that mind, the transmission works as advertised. Want to see how fast it shifts flat out? Skip to 1:05 of this video.
I've been a huge fan of Michelin PSS tires and exclusively bought them for the Mustang over the last four years. So how did I end up here? This year, I was hugely interested in trying an "R-comp" tire. I had my eyes set on Bridgestone Potenza RE-71R's for two simple reasons: price and reputation. Although not a true "R-comp" tire on paper, it performs like one by the account of every single test and review I've read (down to wear rates...). They seem like they're easily the most affordable (from a big brand) R-comp tire and combine that with a reputation for having tons of grip, it was an easy top contender. I had my concerns, though. For one, I'm told and have read that they are an autox tire, not really designed for high speed, pressure, and temps associated with open track. For another, the Mustang is a heavy car (as far as track cars are concerned) being roughly 3,800 lb. (including driver), which will amplify the unwanted open track load...
