MB Factory Sport Suspension
I found that on test-driving stock 2006 CLK's that they felt a little less 'buttoned-down' than the car with the sport suspension. I do not know what is different but I would assume that the springs are not the same; the ride was not stiffer so I assume that the shocks were the same.
The sport suspension does not compare with the CLK 55 I tried: that suspension is much better controlled but leads to a noticeably stiffer ride.
New lowering springs will also be very different from the sport suspension.
