Just buying the coilover spring without the shocks or struts can them to blow. Try and find a full system. When I installed coilovers in my vehicle my suspension lasted about a month before my wheels were hitting on the inside. If you want to lower you vehicle and have a smooth ride try TEIN lower springs or Eibach or TENZO. If you really want a full coilover system try Skunk2 they have a very good system pretty cheap.http://cgi.ebay.com/ebaymotors/SKUNK...QQcmdZViewItem
