Correct me if I am wrong but I was told there was a bolt on kit from Brembro. I think F40(??) was the brake package, but it has been a while since then so I could be remembering wrong. Same brakes that were fitted on the supercharged Axiom semi-concept set up that was doing the rounds at car shows last year. I could never figure out why we had bigger rotors in the back either, odd but those engineers are definitely in the know.
