converting to manual brakes questions.
 

Well finally getting around to installing the rear disc brake kit that I got from wilwood about 1 1/2 years ago. I ordered a 12 bolt from prodigy and hope to have it deleivered this week.

my questions are, should I go ahead and convert the car to manual brakes, or just buy a porpitiom valve and keep the stock power/master cylinder that I have? also which master cylinder do people recommend? is there one with a porption valve in it?

My plans are for a ls1 with a big cam 6 speed this winter/ spring.
