This.
Couple of points though. The Quad4 cars were given rear discs to replace their stock rear drums, allegedly because there was a problem with them. I've asked about this several times, but nobody seems to know when and why this seemingly radical departure from the IT philosophy was allowed. And IIRC, in response to a request for something that would increase engine longevity, the AS folks were pretty much told that increased longevity was deemed to be a competitive advantage.
BTW, I've ignored the nonsense from the guy w/ the 242 Volvo because, well, just because!
