I was looking through the tech articles and came across a reference to gaining 1.5'S in the 1/4 by changing out the crush bearing to a roller on the front end of a 904, now I can't find it. Does anyone know what I'm talking about and if so where is it?
Thanks,
Charlie

The gain from completely rollerizing the A904 is only a couple of tenths at the most. So 0.15 seconds is probably reasonable. Not 1.5 seconds. This mod takes machine work on internal hard part to make space for roller bearings where there were thrust washers originally. It's a pretty good chunk of change for the ET reduction, but that's the name of the game for Stock Eliminator.
