These types of cast iron brake drum are exclusive to Four Ashes. 

These are replacement front (wide) and rear (narrow) cast iron drums for early Felthams up to the DB2/4 MkI but can be used on the MkII & early MkIIIs, we have tried to copy the original design as far as possible to get 'near as original' as possible

As they are a STD profile they can be used with STD DB2, DB2/4 wheels aswell as DB MkIII or DB4 wheels.

They are chemi-blacked, then painted with high temp paint & finally finish ground once an order is taken.

Our Competition version available which can be used in FIA competition (October 2015 Ruling), requires to use of MkIII or DB4 Wheels

Alfin aluminium drums also available to replace standard drums, these are not manufactured for us & have not been tested under severe conditions, OK for a road car though.

Note that the drum in the photo is covered in anti-rust coating which washes off with degreasant.
