Unsprung weight

[Mike & Jaye Rosen <mra@sympatico.ca>]

A general question: I race a 1958 special which has Morris Minor suspension and 
MGA 
drums front (from a 1500), MGA rear axle and diff with 1500 drums all on 
Triumph 15" 
steel wheels. For a little car it's a real tank - 1200lbs.
Anyone have any tricks for reducing the weight (especially unsprung) of any of 
this. I 
have been trying to find alum. drums etc for MGA but haven't seen anything. Any 
help 
would be appreciated.
