Hey I don’t care, it’s your car so build it the way you want and drive the crap out of it. Better that than the scrapper.
All I’m saying is you’ve got a long way to go and a bunch of money to spend before you get all wrapped up in which disk kit you’re going to run, and some of those decisions may change your brake choice.
Direct fit that will handle 700 hp? Yeah if you don’t run a built 9” then you’re looking at a Dana. Nothing you’re going to find at a yard will handle that and be a direct fit.
