"Spitfire" brake disc bolt PCD

[rj]

Does anyone happen to know the detailed specs of the brake discs used (at least on older cars)?

Acording to the Brembo website I've found this:

Diameter 232mm, height 26.2mm and centering diameter is 66.7mm. Thickness is 9.6 wand wear limit 8.3mm

There's nothing about the bolt PCD nor the thickness of the flange.

Does anyone know the exact data - or where to find them?

Thanks

Thanks Ian

Where is the info I need on their page?

I am going to try something on the rears that does not involve Spitfire discs nor Sierra calipers.

Do either of these help?

Yes and no:

In the second link there's a drawaing and some text.

Bolt circle 88.61 in the drawing; 86.61 in the text.

I would guess that the drawing is the correct, and I can measure the pcd within a couple of mm...

Thanks
