okay can someone answer this for me...is the cbr caliper 40 mm or 90 mm center. i have found some nissin 6 piston calipers stnd mount or a brembo 4 piston with 65 mm center and i dont know which ones to pick...cost isnt really a problem, i just want some good calipers. and i am upgrading caliper bracket so that i can run 310mm rotors with EBC kit with standard calipers but i want to upgrade standard to either of the 2 forementioned calipers for stop on a dime breaking power.

 

this might help...
