Did anyone ever do a hardtop for the Spyder?

I know RDM started to develop one, they had full sized plug very near completion.
Not sure what happened to it, if it ever made it to Westfield?

That looks brilliant Peter!

Like how you've done your windscreen as well.

Windscreen has no edge seal at present.
After the car is sprayed this can be filled with polyurethane or left open.
No wind noise so option

Can the join between the two halves slide? I am thinking about torsional rigidity of the car and whether the roof can make it stiffer. The four corner fixtures would need to be solid. Would be interesting to jack up one corner of the car and look for movement.

I would be extremely worried if the original roof was part of the stiffness.
Try it - easy to bend a thin piece of GRP with no core

Sure. I was just musing as to whether the roof insert could be (re)designed to usefully increase the stiffness.

Probably moot since the Libra and Spyder have excellent torsional stiffness in the first place.

A bonded in panel with thick foam core would do that.
Big boxes around the opening however are very stiff
Only for Racing?

For me wind in hair is more important
