Used Stasis Tracksport Coilovers w/ konis for C5 A6. I purchased these from a local Quattro Club driving instructor in 2005 with plans to put them on my A6 2.7T. I traded the car back in late '06 and they have sat in my basement unused... Oh well. The springs have been softened from 700lbs to 450lbs. One of the front koni struts is blown, the result of a killer New England pothole. The strut needs to be replaced- Stasis quoted me $250 and was well acquainted with the original owner as he was a beta tester for this suspension setup. Someone needs to install these and enjoy them! Will ship at buyer expense. Feel free to email me at [email protected] with any questions. $425.
