A fairly recent Grassroots motorsport article (on their web archives at
<http://www.grmotorsports.com/boneyard.html>) suggests that aluminum finned
brake drums from a Datsun 240Z is a worthwhile swap. Is the advantage
merely better cooling? Are the finned aluminum drums significantly lighter?
The article also mentions the Datsun drum centers have to be bored out.
I know from my dad's experience with T-series MG's that the Al-Fin drums
for them are very pricy. The 240Z drums are cheap enough that it seems
every Datsun 510 being driven competitively has them on.
