Gents I'm looking for a site where I can check the dimensions of brake discs. I need to know the inner bore diameter of the disc specifically. You know the part which slips over the OD of the wheel hub.

I've seen any number of sites which give the disc OD and centre bore but not this dimension.

Any ideas?

In case you hadn't guessed I'm trying to find an alternative smaller disc to fit some MGZR hubs inside a 14" MX5 wheel.

i used EBC brakes.com

The late 1984-1988 Rover 216 Vitesse had small diameter vented front discs that MIGHT fit.link to disc on Brakes Int website

Its the right diameter and they're only a tenner each.
I know I've seen a site which gave both the front and rear inner bore diameter just can't find it
