I have a 95 TT and the front crank sprocket spacer on my car was flat. The sprocket spacer I recieved in my 120k kit was the one with the beveled edge. In the tech write-up it says "If the lower belt cover doesn't loop around the crank, the bevel edged washer goes on the front with the bevel facing the rear to make the belt fall back onto the sprocket if it were to come forward." Does it really make any difference?
