your dx knuckles will be a trouble maker. mike (brakeexpert) sells milled ITR calipers that will fit over your knuckle. i'm running those and i can tuck them under a 14" wheel still. but that's about the biggest caliper you'll fit under a 14" just fyi. i had to shave off the wheel weights to clear the caliper, that's how close it is.

other than that, you'll need ex knuckles for any gsr, itr, legend calipers etc

read mike's breakdown on properly sizing your MC. it's very important to match it to your brake setup for good pedal control. if the ctr is a 1" then you'll need to find a gsr not just any integra, others came with 15/16". if that's what you are after.
