I don't see how that the 4" shorter belt even fits. I couldn't even get the belt over the socket to get the handle on the tensioner. I went and bought a belt that was an inch shorter (3" shorter than stock) and I barely got it slipped on. Car is a 04 comP g. (Series III ) Im not going to start until I research some more, but any one else use anything other than the recommended 4" shorter belt? What kind of trouble am I looking at? There definitely ain't no slack in the belt. Seems super tight to me
