Just an update on the build, I have almost all the part needed for the irs swap minus some brake hoses. I have been trying to get it done soon but I’m in college right now and don’t have much extra time on my hands.

Does anyone know if the littleshopmfg larger bore master cylinder is any good? I’m thinking I will need a larger master cylinder and maybe change the pedal ratio to get my new brakes to feel right.

Looks to be an off the shelf GMT800 “NBS” MC. I believe that’s been determined to be fact.

NBS MC swaps are discussed widely on GMT400.com

Mine works excellent - Yes there has been ALOT of opinions shared on this forum

I used an Adjustable Proportioning Valve to get the balance needed front to rear
