I'm looking at going to a 15" wheel down from 16" with the dynalite (12.19" rotor) wilwood kit. Has anyone done this? What would I need to go down to the 11" rotor?

I'm hoping I can buy just the rotor and maybe I'd need a bracket for the caliper. If anyone's done this please let me know what you had to do. Thanks in advance.

edit: the car is an EM1

 

Got an email back from Wilwood.. they're saying it's not possible.. I guess I'll just sell em

 

i need a 16 inch wheel for that exact reason, how much? and what kind are they? lemme know...
