Can't agree more. Also be careful who you use. Found that the tyre centre used by my dealer is hopeless. Had what I thought was the "Left Pull" problem, turns out I had half a degree of toe OUT on the front (found once I took it to someone who knew what they were doing).
As for why you'd mod such a stunning suspension package, all I can say is that after the mods my new suspension makes SS+ feel soft and floaty! (Heaps more turn in and mid corner grip too!)
