It doesn't give more sales to either maybe to the purest but like i said "who cares". So a person with a new C63 would have to worry about a new V8 M3 on the track course..what about straight awasys or even on a light on regular streets then the M3 owner has to worry right? Just buy what you prefer people and screw those reviews they get no where with alot of us.

There is no free lunch.

It slows the vehicle through the corners dramatically, as with an open diff and that much torque, you can't put the power down with that much weight transfer going to the outside wheels without spinning the inside wheels, which slows you down, which gives you a nice view of the *** of the M3.

I mean, these folks at Mercedes corporate are just class-A morons. To let their flagship AMGs get demeaned like this over a part that their competition has standard (not to mention Camaro SSs, Z28s, Trans Ams, Mustangs GTs/Cobras, and the like all have as well) and which would cost them a few hundred extra to install at most is just pathetic.

Apparently, the wizards in their marketing department have not yet figured out that these track numbers play a big role in which car wins these comparos, which in turn plays a big role in which car many the people who read these comparos will buy.

Oh, well...get used to it until they wise up and start giving their cars the same traction potential as the competition.
