To change the default player's face & helmet you must :
Put your choice of plaface.mip into the cars>carsF2>Brabham folder.
Put your choice of plahelm.mip into the cars>carsF2>Ferrari folder.
(Make sure you backup the default files in case you are not happy & want to go back to them.)
Thanks to Greg (gliebzeit) & Tommie (Tvo) for solving it for us.
