ok guys so i am having a hard timing find answers to some questions. When you buy a set of used Koni's are you able to have them rebuilt and are they under a warranty now if you do??? My second question is I was looking at koni's threaded sleeves. I want to see how much the price difference is buying the sleeves from koni and getting springs from eibach. But what sleeves do i get?? they have a sleeve with a 42mm ID sleeve and a 50mm ID sleeve? also does ground control sell the spring seperately or by a pair on their site.

Thanks H-T , Help me slam my DB8!!
