Old question, new (possible) solution
 

I know we've discussed and shot-down the idea of getting disc brakes in the back end of the Pro's with drums... mostly due to the absence of a kit and hardeware to do it... I have another question to that theroy though. What if you took the discs off a Miata and put them back there. They are the same size as ours and come in both 4 AND 5 lugs? On a side note to that, would it be feasable to but the Brembo BIG Brake kit on the fronts, also using the Miata application since their stock rotors are the same as ours... is the hardware the same or am I just beating a mutilated horse?

Oh man, if it would be possible to get the Brembo big brake kit on there that would be AWESOME! And although I dont know the specs of anything, it sounds like a good idea and even if it doesnt work, good thinking!
