i need new suspension for my tour and im wondering what the cheapest would be and how much stock springs and struts would be from a dealer ship. i am thinking about getting BAT suspension kits but i'd like something cheaper.

2000 contour V6 ATX BAT suspension kit, k&n filter, SVT TB, SVT UIM, SVT LIM, MSDS headers, MSDS Y-pipe, SVT dual exhaust, Custum burned ADC chip, 7000k HID's, 200 amp HO alt, custom gauges, and 17" rims
