Jasper, let me know what you eventually end up with as I'd like to order some. I've had a brembo billet on the shelf in my living room for the last year (the pair to my DD l/h caliper) and even the bolts on that have gone rusty!!
Incidentally, I'll be out at the brembo factory shortly so I'll ask why they fit such crappy bolts!
Cheers,
Ali
