I wrote a while back asking about what I understand is/was a popular
modification, fitting Datsun 240Z finned aluminum brake drums.
I ended up getting a set at a reasonable cost. I then *carefully* used a
drum sander to remove about 0.5mm of material from the hub center hole,
stopping frequently to test fit. After just a few minutes, a perfect fit!
... on the right-hand side.
It seems that on my car, the brake backing plate/dust cover on the left
hand side is ever so slightly larger than that on the right hand side, so
the Datsun drum, which has a slot to receive the lip of the backing plate,
doesn't fit on the left. Looks like I have to machine out the slot a bit.
I do think that it'll be a neat modification whenever I can get the work
done - less rotating mass, better cooling, and sharp looking.
For those of you with brake backing plates that match and are the right
size, this should be a really easy swap.
