Went to Mb yesterday and picked up a set of front anti-roll bar bushes. When I removed mine I found the part numbers were different and the new ones did not fit. I called the dealership and was told the car has an option called 'road enhancement pack' and they think a sports under carraige. On the russian VIN checker it does not come up as a sportsline and I dont have sportsline interior s\wheel or gear knob. The car was also specced with AMG body kit and wheels, is it possible just the sportsline suspension was fitted? The normal bushes are: inner 124-323-56-85, 26.5mm outer 124-323-49-85 18mm The ones on mine are: inner 124-323-45-85, 27.5mm outer 124-323-51-85, 22mm Ive found a document which details the above as been fitted to a vehicle with "Sports undercarriage", the same document states "Sports undercarriage" means "Sportline". Im not sure, anyone know if those part numbers are the same as a sportsline model?
