Hi. These are pretty much brand new. They have about 150 miles on them and are in perfect condition. They came off my 2003 cobra when I put on Maximum Motorsports coilovers. These will safely lower your 1999-2001 cobra to the same stats as the 2003 Cobra, without adversly affecting roll center, roll axis, bump-steer, etc. (Alignment still recommended) Lower your car to a reasonable height without sacraficing ride quality, and get better handling with the revised spring rates and high quality struts/shocks with optimized valving. I will ship 4 Bilsteins and 4 springs for $450 in the US, excluding Hawaii and Alaska. 1 set only. Email me at [email protected]
