If, so it should not be that much better than the stock 16v suspension, unless yours is worn (which mine is). I was thinking of going with the H&R springs for $231 and either the KYB front struts for $61ea. or Koni adjustables for $181ea.. I am keeping the SLS rear for ride quality and originality. As for swaybars, I have heard that the sportline front swaybar is a good upgrade, or you can use a 500e front bar (you will need to cut it a bit though). I am interested in more performance than the MB sportline kit offers. I also want the car to sit a bit lower than the sportline kit. Hopefully Tire Rack will be able to fill my needs.
