Don't have clue, wild guess - less than 20%?
Heres a link to the 355mm allloy bell jobbies that come with the AD 6 piston AP racing calipers.
I can tell you they look bigger in real life!
Hmm but I don't see any link to 330mm discs.
Maybe they didn't get around to making them then, but I know they often have more stuff than is on the Website.
Could be worth an e-mail to them?
