Chiragp/Luke/et al:

I think I'm going to go with the 215/50VR-16 BF Goodrich Comp T/A VR4s. Can't beat the (Tirerack) price of $62.00 each. I'm going to e-mail you Luke and see if I can't get a mercedesshop.com member discount on the 4 tires and Eibach Sport Spring Kit

PS -- Thanks everyone for the information and options.
