Hi Martin, John Freeth of Performance Braking in UK has designed and made me discs / rotors for my Mangusta. John used to run Girling Race Dept. top guy. I'm not sure whether he did my front or rears or both as well, I will need to check with garage on Monday if the fronts were replaced. Somewhere I have the specification for you to check. f you contact John tell him you want the same as he made for Larry Tucker (me). I also had a company in UK make a close ratio steering rack if you want details
Cheers
(Anything else message me)
