They are bigger than your CX brakes that's for sure. I suggest just getting a full conversion, looks good & works good. Don't cry over the Prelude not working, there's no reason to favor those over the Integra anyways. I've seen complete GSR changeovers, all 4 corners everything you need + the booster and master cylinder for $500-$600. It could come with brake lines too but maybe you want to change to stainless while your at it, use the ones for 99-00 Si. You could also use the entire brake swap for the 99-00 Si in fact, same as Integra.
The AEM kit is over $400 and all it is is larger front rotors, a set of pads, and relocation brackets for stock calipers. I don't think it's worth it.
