Photography by: Graham MacNeil Ford really wants to sell you a Mustang with a turbo four cylinder. They started by derating the V6 engine in the 2015 S550 compared to the 2011-2014 S197 V6 to make the EcoBoost 2.3 litre more differentiated. Then, they offered a performance pack on the EcoBoost but not on the V6. Now, they killed the V6 all together for 2018 and will only sell you a V8 or this EcoBoost. I love a good V8, everyone who knows me knows that. This is a Mustang, which means it needs a V8. If those aren't enough reasons, I always prefer natural aspiration over forced induction. That's three strikes against the EcoBoost-powered Mustang. But I'd be lying if I said the idea never intrigued me. It's the lightest (if you account for features). It has the best weight distribution. It has the same great chassis as the GT. It's very affordable and it has a lot of potential to make more power. Aftermarket? Endless support. There's plenty of good about it....
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...
