" It is official, Quaife has a limited slip differential upgrade available for the C207 Mercedes-Benz E550 models. With the torque the M278 twin turbo V8 generates a limited slip differential becomes necessary to maintain traction and definitely will improve putting the power down in corners especially as well as the straightline or low traction conditions (rain, snow). The diff is a direct replacement for the factory open differential. It will not interfere with the electronics or cause any malfunction lights.
The differential will also eliminate a degree of torque steer from the factory open diff. Quite simply, it's a great upgrade for the rear wheel drive E550 coupes. The diff comes with a lifetime warranty and will be available in July.
Great of Quaife to take care of a definite need for C207 E550 owners.
