I recently installed a H & R Cup Kit for my 2002 c-class w203. The car looks amazing and handles very well on tight cornering. The Cup kit comes with lowering springs and matched shocks from Bilstein. The front drop is 2.0' and the raer is 1.5'. No caster/camber adjustments are necessary as long as you have a very capable shop do the work for you. Rolling the fenders is not necessary as long as your rims are 19' or smaller. Make sure you have the shop re-align your car to avoid problems.
