Dave, the fronts are the 5-spoke 17x8 ET37 "E430 sport" wheels, and the rears are R129 wheels which look EXACTLY like the fronts but are 17x8.25 ET34. As for the control arms, I went with the regular 124-330-35/34-07 ones - late style with the non-removable ball joint. They were a LOT cheaper than the Sportline ones, that's for sure!
On a side note, you should pick up the 2006 "Geniune Mercedes-Benz Accessories Wheels" brochure from your local MB dealer. They have LOTS of neat looking wheels with part numbers and all dimensions. The W209, R171, and W203 all have a good selection of 17x7.5 ET37 wheels, which IMO is the perfect size wheel for a lowered non-500E 124! If you can't get ahold of the catalog, I can send one over... -Aaron
