Thanks to Ivano Cimaglia, G40R owner in Italy for advising that AP5000+ front calipers should also fit, possibly the CP5040-10/-11/-12/-13 - 130mm Centres.

For non-Ginetta racing I've been told that alternative brake pads will fit, but I've never tried them. The types mentioned are as follows:
G40 race cars are fitted with an FIA homologated Lifeline Zero 2000 (bottle dimensions 30x15 cm), 2.0 litre, 2.25 kg extinguisher, plumbed to fire manually via cable. These must be serviced every two years (by Lifeline agents if you need to comply with FIA, not just MSA homologation) to comply with MSA Blue Book regulations (scrutineering).

The inner lamp is the main beam (low beam). Replacement lamps are available from Ginetta (part G50-L0029) at approximately £143 inc. VAT, or possibly from Car Builder Solutions: https://www.carbuildersolutions.com/uk/70mm-projector-dip-beam-headlamp-rhd-compact-lamp.
For better vision on track, the long-view type mirrors can be fitted in front of the factory mirror, clamped onto the roll cage. The following mirror is available from Amazon for approximately £20 and although the clamps do not fit the diameter of the roll cage, you can secure them with cable ties: https://www.amazon.co.uk/gp/product/B01J149BFK/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1
The mirrors on the G40 GRDC, G40 Cup and road car are the same as the mirror from a BMW Mini, Mark 1.
Quantum One Zero are available from Ginetta or possibly direct from the manufacturer. The front and rear dampers are different, so specify which you need.

The Michelin racing tyres are available for 17", but may be too big on inflated diameter, so would need confirming for the 7.5" rim (and comparing to the inflated diameter of the Avons, which are 590 mm):
