i was talking to a guy at my local benz dealership...and he was a cool guy and he completly suggested me to get the kleeman pulleys or possibly amg....he said it was the biggest upgrade possible for my 2002 coupe....i know there is a lot of talk about them and people saying they will do the upgrade, but did anyone here actually do it...only post reply if you did the upgrade, not if you are thinking about it

Kleemann pulleys are no longer sold in the United States. Wetterauer no longer sells pulleys anywhere. AMG never made any. ASP Racing, Renntech, Carlsson, Vaeth, Brabus, and Opera Design offer pulleys and pulley kits.
