I was thinking about getting some Bilstein shocks for my 92 300E. However, I am having a hard time deciding on the 'comfort' or the 'sport' shock. Will I really be gaining that much from the sport shock? Does the advantaged outweigh the disadvantages on the sport (ie: very stiff=horrible ride, but handles better than a Corvette ). I hope someone with experience on these shocks can give me some idea. Are the Bilstein shocks self-leveling for the rear?
