Survey again, Alum flywheel

[302 LX Eric]

A steel wheel will allow the engine to maintain RPM between shifts, prolonging clutch life and making for smoother shifts.
An alloy wheel allows the RPM to fall rapidly between shifts, which can cause a 'jerk' each time the next gear is engaged.

In racing applications this is really a moot point. Especially in drag racing where your shifts are very, very quick - therefore your drop in RPM is really non-existant.

Also, to be honest with you, I've really haven't noticed this 'jerk' that you're referring to - even when just cruising around on the streets. I'll pay more attention next time I get my Mustang out, but I really don't recall anything like that.
