Hey Everyone! Im thinking about lowering my 2011 E-350 Coupe and was curious as to which is the best route to go since its my Daily Driver!

Should i just change the springs? or Do Coilovers? Air Suspension?


was looking on Ebay and found these: http://www.ebay.com/itm/KSport-Kontr...89d475&vxp=mtr

will these work? and is this the recommended way of going??
