I'm considering fitting a Quaife ATB limited slip diff to my SLK and also lowering the final drive to improve acceleration.
I believe the standard diff ratio is 2.8 and a change to 3.1 would be beneficial (to acceleration if not cruising!)
Quaife cannot supply a new crown wheel and pinion.
Does anyone know if there is a suitable diff available from another model?
Any advice gratefully received.

AMG have a proper LSD for the R172 which comes standard on the performance pack cars - I'd go for that instead and give it an ECU remap to get better acceleration.
