Hi all. My apologies if this has been a deep subject before, but I was hearing all over the forum "bla bla ALK fitted" etc and nothing to explain them. I didn't know what these were to begin with except something suspension related. I found this lil gem of a write up on the interweb and it gave me a very reasonable explanation. For those that might be interested, below is a link. http://forums.nasioc.com/forums/showthread.php?p=8384387
