STEEL VS ALUMINUM FLYWHEELS ?

I think he means it has a 'glas body. 'Real' Cobras are worth the better part of a million dollars---give-or-take-a-few---and most owners probably don't drive them much.

Hi, so do the aluminum flywheels have a steel insert so they do not wear out so fast, I turned one one for a guy in the early 70's for his stock car but it was all aluminum, it had some bad grooves in it so  I made it a lot lighter , after that I didn't think they would work vary long on a street car.

yes on the replaceable steel insert for aluminum wheel

[Leny Mason]

Yes I would think so there is a lot of friction there, a stock car you were all ways working on them so it was not a big deal, on a street car not so much fun to work on all the time. Leny Mason

Schiefer (remember them?) made IIRC the first street/drag aluminum wheels with a sintered iron or steel replaceable
insert just for that reason. While I don't doubt in some applications (sprint cars, maybe stock cars) no insert was used, it was much more typical they were, especially in a drag car/dragster.
