Roll hoop

A roll hoop means I can enter the vehicle in certain race events: mostly sprints and hill climbs against the clock.

There's a lot more to be said on this topic, mainly around what's necessary to homogate a roll hoop to suit Motor Sport New Zealand (MNZ).

It's also a roadable vehicle so the clamshell has to be easy to raise and my dear mother has to be able to climb in and out. This means I needed removable backstays, however removable roll hoop components are tricky because hinge joints are not allowed in MNZ.

The following pictures tell the story.

Plastic hack number 1: Note that it routes in the front of the clamshell behind the firewall. Now that was a mistake.

Let the pros have a go... Ron Robertson.

Rear fixing

Bolted on... a bit of a horror to get a spanner on to it. The clamshell will be down most of the time!!

Water and oil are accessible through the flaps on the clamshell and the engine cover can be removed to access the top of the engine.

More grinding away of fibreglass.

It looks a bit like scaffolding in this shot. In reality the car is very low and the roll hoop barely comes up to a bystander's chest. It looks very purposful. The horizontal bars are for fixing the harness. Note the feet Ron has used. He's welded the hoop to the chassis top and bottom - this is a very strong rear firewall!
