what front disc setup do you use?

Looking to change the front brakes on my 72 duster want to convert from drum to big bolt pattern disc. Car is a racecar and want to see what the best options you guys went with, I need the whole setup if anyone has links to where they got theirs that would be great, I have a lot of options and just want opinions. car goes high 11's just using the motor as a test subject to make sure all is good for the streetcar, but car should go low 10's with the the bb

even if going with a 73 and newer setup with just changing the arm.

I went with the Strange disc kit for the front. Mine is only a drag car. The kit bolts right to the stock 71 drum spindles. The price is similar to the Willwoods, but they are lighter. The complete kit for both sides weigh less than one 9"drumm assy. They are touchy though, you must make sure that the brake pedal comes all the way up and does not rest on the master cylinder or the brakes can drag. I had to put a spring on pedal arm to resolve it.
