I've just fitted SIII Stage One V8 axles to my V6 lightweight, along with all the brake parts, those 3 inch wide x 11 inch front shoes sure make a hell of a difference. I have left the standard Lightweight servo unit on and have no problems stopping although there is a lot of pedal travel.
Althought there are two front LWB cylinders, there is only one piston per cylinder so volume of fluid displaced remains the same or v. similar to the SWB cylinder on SIII vehicles. Assuming the diameter of cylinder is the same. Even up grading from inch and one eighth cylinders to inch and one quarter cylinders you will not notice much difference in pedal travel due to greater volume of fluid required.

The more/bigger the cylinders you fit, the greater the volume of fluid you will require to operate the brakes effectively so in theory you should need to fit a bigger master, but in practice I find you can use the standard lightweight master cylinder

Sorry for the double posting, slipped with the mouse!!
