Another option that I havent seen posted yet is the mini cooper 'bigger brake' upgrade:
Rotors from ~05/06 mini are 280mm, which are 2mm off ITR/Prelude BB6/CRV(?) rotors, also offset is within a ~1mm to honda specs.
Also rotors are 4x100
Then you can run ITR/Prelude BB6 calipers without the need for 5x114.3 conversion, calipers should mount up fine to 262mm ek hubs.

Google 'integra mini brake upgrade' - first result, heaps of documented info on this swap.

Also I got quoted $60 per side for standard replacement mini cooper rotors. Then what ever a pair of calipers set you back
So if you want a bump in stopping power, consider this upgrade
