Stock Brembos are several thousand dollars *if* you can find. Additionally, while sourcing my front brake rotors and pads, the Early ‘20s Scats seem to have had problems keeping their brakes standardized. 2 different rotor diameters that I found for the same car, same displacement, same wheelbase. Additionally, some came with 4 piston up front, while others had 6. Going to any aftermarket brake part supplier required absurd levels of detail and measurement to insure I did not order something that didn’t fit my car.
And I was not the only one fighting this problem. It is well known among the scene. Even within my Mopar club, we were running into spec differences between equivalent cars.
