GoodSpeed Performance is now offering Quaife for Mercedes.

Quaife ATB Helical LSD differential for Mercedes Benz.

This modification is a must for C32, and E55. We have found that even cars with stock power levels benefit greatly from the Quaife differential. It will offer the driver far superior traction, substantially reduce the need to activate the ESP, and not compromise the feel and drivability on the street. The overall fun and control is absolutely astounding. Quaife differentials with quality installation are now available at GoodSpeed Performance Lab!
