I have an aftermarket k member in my car. It is built with a body spindles. I have a new set of strange race brakes on them . This car is being built to run drag week/race week types of events. I don't trust the small non vented rotors on the drive portion of the event. Last year years there were some mountain roads that I'm sure would have cooked the brakes off the car. I have access to some mustang ii spindles and brakes, but was curious if the swap was plausible, before pulling stuff apart.
