A few reviews of the BMW M5 haven't been too positive - it has improved as a luxury car but moved further away from the "Ultimate Driving Machine." If you have an M5 or an M6 and you agree with these reviews, BMW might have an answer. Starting with model year 2014, BMW will offer a performance package called the Competition Package. The package will bump power from 560 hp to 575 hp. Other upgrades include distinct wheels, black exhaust tips, and, more importantly, a revised suspension and a more direct steering ratio. The revised suspension should sharpen up the handling and, judging by the reviews, should be a welcome upgrade to BMW M fans. Top speed will remain governed at 190 mph and 0-60 mph time should drop by 0.1 s to 3.6 s. We'll have to wait for an official release for more details about the suspension upgrades and pricing but, considering that the M5 and M6's aren't set up equally, (full post: BMW M6 Coupe - The Ultimate Twin-Turbo M Car! ), 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...
