Guys does anybody know what measurement is of the spacing of the bolt holes that holds the caliper onto the stub axle? This is for the 6 piston Brembo caliper, in metric if possible, I believe the old spacing was 130 mm for calipers on the 993 twin turbo etc.

I don't think it is that small I was told more like 222mm for the 6 piston type, maybe 142 mm for the 4 piston GT3 caliper that came out with the 330 mm disc? What size discs did the GT2s have? With 18s I can't run bigger than 355 mm. Anybody know? I would prefer steel brakes as I heard that the carbon ones don't like the track much, or have they improved?

The 350 mm discs appear to have a bigger swept area than the Ferrari 5o setup I have on one of my 928s, if I was to use this setup I would need a two piece disc so that I could use a custom hat. Do you or anybody else know of any options there?
Do anybody know the width of the brake pad? The F50 is a really nice light disc, it is only 32 mm wide, I suspect that these are 34 mm wide?

I downloaded a tech drawing from Brembo and that states that the 6 piston off the shelf Brembo caliper has a spacing of 200 mm. Maybe the pics I saw of the Porsche one are unique to Porsche.
I will check the Ferodo pages, thanks for the assistance, it is appreciated.
