Disc brake upgrade questions

I would never consider anything smaller than the 11 3/4" police/taxi rotors & calipers for the front. Add a rear Econo disc kit from Dr Diff for a few hundred and you can retain and use your 4 wheel drum brake kit distribution valve and light switch. If you have manual brakes, run a smaller than 1" bore master cylinder.

This combination is extremely well balanced, provides dramatically improved braking, pedal feedback and modulation and is much safer overall. I am running this same set-up on my a-body and my e-body with a big block and power assist. The manual brake are much easier to modulate during high speed, spirited driving on road courses.

In the end, its a little money well spent to stop better.
