As the parts are machined in house, we hold a good stock of internal spare parts too.

Please contact us and let us know what parts you need and we will do our best to help.


Previously BG Developments had the pleasure of working on the original GT40 which finished 3rd at Le Mans 1966, (when they famously finished in 1st, 2nd, 3rd formation). The car was put  back to its correct braking set up so that It could compete at the Le Mans Classic. At some point in it's past it was fitted modern 4 pot calipers, which eliminated it from FIA events.

At the factory, we manufactured the correct calipers, discs and mounting bells to the original specifications - and the car has since competed in several races with great success.
