I'm sure there are some out there who would think that messing with the iconic 911 shape is blasphemy. But for the rest of us, this 911 may just be the prettiest 911 ever made. The reason you probably have never heard of it is because only one was ever made and it was built over 50 years ago. Back in the early 911 days (i.e. 1960's-1970's), Porsche didn't make a 911 Cabriolet. The engineers in Stuttgart didn't think they could design a convertible version (or perhaps feasibly build one) that would meet the American National Highway Traffic Safety Administration (NHTSA) rollover safety regulations, which is part of the reason the 911 Targa exists. Since the American market was quite important to Porsche as far as sales and profitability of the 911, a convertible wasn't built back then. It wasn't until 1981 that Porsche showed the world a concept 911 Cabriolet at the Frankfurt Motor Show and a production version didn't come out until late 1982 as
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
