Need whole new brake package for 1970 A-body, looking for input

[CreepinDeth]

I can confirm the C5 booster push rod is not adjustable.
I can't say in regards to the 2002 Camaro master bore size wise. I just go with a NAPA unit.

Yeah I did some more looking into it, and that's the end result I discovered as well. The C3 vette's is adjustable.
I just ordered a 9" dual diaphragm for the GM A-Body with a Wilwood 1" bore master & prop valve from Pirate Jacks.

My C5 calipers arrived today, along with my CPP A/F/X spindles.
Now I just need to get the rest delivered so I can begin ripping it apart and rebuilding.

Thanks for the input

While I understand your point, I would counter that comparing Gen 9 and Gen 10 Accords (with and without iBoosters) is not the same as comparing a 1970 Cutlass with a vacuum booster vs. with a iBooster. There is proprietary software loaded into the iBooster in OE applications that customizes pedal feel and makes it play nice with abs and collision avoidance systems. None of that is present in a retrofit application, only the pedal position sensor is utilized. In a retrofit application the difference in braking performance isn’t just noticeable, it’s dramatic.

Fair enough, I will just wait for the proof to be shown in autocross or something along the lines of race tested and proven over X time.
Forgive me if I'm just anti-tech in this regard with all the over-complicated systems I've got to deal with daily,

I just bought and sold a new Hybrid SUV I was testing out for 3 years.
Just sold it because of the overcomplicated electronics, I got rid of it and went back to an Accord for DD

I'm noticing a pattern of overcomplicated electronics, failures and costly repairs. I want to K.I.S.S. my setup with a multi-decade proven setup for now.
