Anyone know the engine weight for the all cars on 2003 grid? I've heard all season that the Honda engines are heavy, but never seen an exact figure. I'd like to see just how heavy they are relative to the other engines.

Ferrari and BMW engines are supposed to be weighing just under 90kg.

Brass sump?

Shim material?

Ballast I expect, it has the right sort of thermal expansion coefficient, and it machines well - plus it polishes up nicely....
