Jaguar and Evo Brembo Calipers - Piston Diameter?

[EddyP]

I'm trying to find some nice 4 pot brembos that have a fairly small piston diameter, does anybody know the diameter of them on the Jaguar R brakes, or the type fitted to lots of Evos?

Thanks

36mm and 40mm iirc. 2 sizes to cut down on taper wear.
