i've been searching for a while on a few sites for full info but haven't had what i need.

wondering what parts do i need to buy to put ba/bf calipers onto a au series 2?
obviously i know i need calipers but what else do i need for the front?
as for rotors i'm getting DBA T2 slotted ones with bendix ultimate pads.

And for the rear, there is not much info about the rear except for could be a lot of work! would i be better putting slotted au rotors (DBA T2 287mm ones i think) with decent pads?

a list of what i need or even photo's of what to do on the rear if its easy would be great.

Check, Troymans AU build, Papa Smurfs Build Thread as well as Jew Matt's Fairute Build Thread, They have all fitted upgraded brakes to their AU's.
