Davek - you hit the nail. Thanks for the Pictures of the Group 5 Lockheed brakes - I've never seen real ones.
Panteras were homologated to use these in apr 1975.
These are not the original calipers but repro's machined from billet aluminum rather than cast like the originals. They were made with permission from AP, which also supplied the drawings used.
They are made for the two race panteras build by Aquila Racing i Denmark. I meet with the owner of the company, Dan Suenson, yesterday to hear about his experiences with the panteras. I was blown away with the things they did to those cars. The brakes are just an example. Apparently, those two panteras were blowing away everything in their class on the historic scene at the time.
Here's one of the cars for sale, I think they are in the 150 k euro range, but that is, according to Dan, VERY CHEAP compared to the money and Development that has been put into Building them.
