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.

2012 Boss 302 on square 305/30/19 RE-71R's at AMP - Graham MacNeil © For better or for worse, I have heard and read so much about RE-71R's. Everyone swears by the grip but complains about the wear. Generally speaking, the pros are: 1. They grip as well or better than most R comps. 2. They don't wear as quickly as R comps if driven occasionally on the street. 3.

In the popular 200 TW category, they are faster than the popular Hankook RS-4's and BFGoodrich Rival S's according to published Tire Rack Tests. According to plenty of reviews, they are also faster than well established R comps like R888R's (which don't seem to work too well on heavy cars anyway) and the venerable NT01's. But I was still hesitant for a while until I talked to a tire tech support gentleman...
