Brake rotor help

I am hoping someone on this forum may know what British car has this size brake rotor.(see sizes below). Our RF 80 Van Diemen formula ford is said to use a stock british car brake rotor, possibly a Trimuph GT6.The main issue is the height of the “hat” which is much shorter at only ½ inch. Any help in resolving this issue would be greatly appreciated.
Current rotor dimension are
Hat height = .50”
Hat I.D. = 2.62”
Hat dia 5.45”
Worn rotor thickness .31”
Disc dia = 9.75”
Bolt circle = 4 X 3.75
Stud hole = 3/8”
I attach pictures of the rotor.

I don't know what you've got, but Brembo might be able to help:

https://www.brembo.com/ENG/AfterMarketBrakes/Brembo+Catalogues/SearchCars.htm

Lets you enter the relevant dimensions and then identifies what Brembo rotors have the same characteristics. It works on partial data too, so if the full entry turns up nothing you can drop some dimensions and see what might come close.

Alternatively, you can choose the make and model and it will turn up the relevant Brembo disk and will provide the dimensions too. This is for a Spitfire- they didn't have the GT6 one, it seems:

Hope this helps....
 
That rotor doesn't look like it came from a Spitfire or a GT6. The Triumph rotors don't have a 4x3.75 bolt pattern unless this one was custom drilled. Have you tried Pegasus for a replacement?
