POSI vs SPOOL

[Jeff Lee]

I have a MW lite-weight steel spool in my Dana 60 and as Ed says, there's a reason. I'm not giving up strength / deflection for a small advantage (if any). But I believe the small engine / no HP car is the one I would use the lite-weight parts on. I've seen some impressive results on a V6 stocker by going this route; especially what I said about slick size.
