duck,
I'm not a fan of Eibach so I never really checked out the drop for their springs. H&R advertise a 1.3in drop and with the 1 dot pad my rear wheels are tucked in the fender and the front is right at the fender lip.
The shiftknob install on the W202 is different than the W201 or W124 where the shaft does not need to be replaced. Simple undo the lower collar by twisting it and it slides right off. The installation of the MOMO knob is like any installation you would do to a manual car.
I actaully got the MOMO knob from Paul(he has an SLK here on the board but I dont know if he still post here)
Here's a shot (abit bad) of the interior)
