If I spend £90,000 on a car I want to see a premium brand on the brakes, the Aero Cars all have AP Racing, which is as good a brand as it gets: they are owned by Brembo. Virtually all European premium sports cars use Brembo or AP Racing brakes.

As has been said the supplier is Spanish, and with a significant Indian manufacturing capability. The main image on their website is of a tractor.... not a car. From a press release issued by them a few years ago...

"Frenos Iruna designs, develops and manufactures brake components systems for automotive and off-highway vehicles mostly related to agricultural and public works like tractors, excavators, dumpers and forest machinery, among others"

Really?

I did a few web searches to see if I could find details of their main customers. I didn't get anything.
