One of the things we had to address with the car was a means of securing the bonnet and tailgate which is compliant with the Motor Sport Association (MSA) regulations and FIA regs as well. The standard bonnet locks and tailgate locks are not by themselves acceptable.
Rally cars seem to use externally sprung toggles or simple bonnet pins neither of which are particularly attractive to look at or secure.
Many circuit racing GT cars seem to use the Aerocatch type of fastener so I decided to buy a pair to see if we could use them on the Four, I wasn't too sure because of the compound curvature on the bonnet and the depth of the tailgate. I went for the flush type initially. This does away with the need for an external mounting flange. They can be either bonded from the underside of the panel or screwed on. In our case we went for the screw option as it was simpler than bonding.

Fitted this type to the RT Performance carbon tailgate. Fortunately there was enough 'height' in the pins to mount them to the tailgate aperture and still lock to the catches mounted on the tailgate.

Fitted these to the OEM aluminium bonnet. Decided to just go for the simple screw-on option. The bonnet has not yet been fully prepped and sprayed to the final finish should look better.

We are going to fit one of these on each side of the C-One nose section to secure it to the front wing. Originally it looked like we would need to get the bodyshop to fit them but on closer examination it does look like a DIY job. Care will have to be taken, particularly with the C-One GRP front nose section when cutting the slots for the catch.
If they are good enough for these guys then they're good enough for me!
