I've never seen an FRP fitted with standard brakes
Go visit Chris, he'll sort you out..although if you need new discs, parts, pistons, pads it's not a cheap ride but once you've got on top of it, keeping them serviced shouldn't be too bad.
Don't do things cheap else you'll end up with a bodge FRP that you won't want to drive and then end up spending more as you'll want to put everything as it should be.
You could consider an alternative calliper such as the hi-spec model.
