Glen- I went back to 16-inch tires for everyday street use due to the wife complaining that the SportLine suspension is stiffer than the 500E.
Not too bad, but maybe I should go for the early year 500E front dampers/shocks.
Do you still like them? Wife factor?
I do have a set of Bilstein Heavy Duty's (and Sports!), but I've heard these are still stiffer than 500E dampers, and of course don't have the internal buffers.
