I'm trying to understand the need for brake improvement for any Mercedes since they started using four wheel disks. Barring an all out racing situation, there's plenty of brakes on these cars.
I've hauled my 300E down from 140 MPH before in amazingly quick, controllable style. I don't think any of my diesel MB's went fast enough to ever need much more than dragging a boot on the ground outside the door.

OUCH larry! you must have one heckofa big boot!

the vented rotors don't give ANY additional stopping power, but they do allow longer sustained braking. anybody that's towing, or climbing large hills can benefit from vented rotors, but don't expect ANY shorter stopping times, or ANY improvement at all under normal or even spirited braking!
