Lowering a 550 AE to ROW height?
 

Hello,
I would like some advice on lowering my 2004 550 to a ROW ride height. I understand I have the US sport suspension so I don't want to spend money on the full ROW suspension if I don't have to. Can I just install springs while using the existing shocks and sway bars? Does anyone sell factory springs or do I need to go with H & R, etc.? I would like to keep about the same ride quality at the ROW M030 suspension as the car is used only on the street. Thanks for any words of wisdom.

You could install just the RoW M030 springs but there's a risk of bottoming the struts on very hard bumps, which is bad. You should install the springs and struts. Call Sunset Porsche in Portland.
