According to the Wilwood website technical diagram https://www.wilwood..../DPHA-cm-lg.jpgand the adjusted mounting location I get 11.4" as the max OD of such an assembly. The stock 14's have just over 11.5" clearance so they could work. In terms of a rotor for such a setup the brembo is quite close: https://www.brembopa.../09-3125-10/pdf I have also been considering a custom hat and rotor from coleman. They are quite reasonably priced and once the specs were done other folks could order them if they were interested.
As to the question of why... the answer is that I want to keep the CRX as close to factory looking as possible from the outside and in but I am in the process of updating the nearly 40 year old car to more modern performance standards.
