He already has ex knuckles, which are the same as integra. Besides, all integras have the SAME brakes...gsr's are NOT special. They may look different from the ls/gs but the piston size and the pad are identical. AND crossdrilled rotors are just plain stupid - they cost too much, they dont do that much really, and they chew up the pads quickly.

If anything, you can follow what I did:
Integra front calipers, ITR 1" brake master cylinder/booster, stainless steel lines, brembo blanks, axxis pads.
I stop very nicely, better than I did previously with the ex/si parts, and have very nice pedal feel.
Total cost, I want to say, was right around $300.

If you want to redrill 11" rotors, from the itr, to 4x100 you can bolt up even nsx/legend calipers to your current knuckles. That is the biggest oem you can go.
