You can use Crx Si 91 brakes they should fit right in, good luck finding one used, (i have a crx91si and finding parts for this car is hell!) But you can surelly get it new from honda wich would be your best bet.
check out napa they got some relativly good prices, but i do suggest getting it new, its really worth it ... with fast cars you need good reliable breaks, but if your looking for cheap prices go to the scrap and pick up everything but the pads and disks (get those new)
sh*t i just thought of something, i have a friend that works and honda(mechanic) and gets cost price for parts all new and he does work in the week ends in his home garage if your interrested email me i'll hook you up with his #
But it would be for later cuz my car doesn't come out in the winter. (Its in the shop getting the "honda" rust out and geting repainted) You're right, I do need a bit more braking power. I mean, its really fun driving fast, but being able to stop really fast is also a + and sooo much more fun. anyways, if you can, hook me up and I'll try to call him!
