I've crashed my roadster!
Here's the video:

And here's the result:
From a preliminary inspection, RS1 has buckled beneath the wishbone bracket, and the camber adjuster has sprung a crack at the seam. The fact that all the chassis seams held is very reassuring :-)
Also, due to lack of clearance both the lower outlets of the thermostat housing have broken off on contact with the chassis.
I haven't gotten the roadster back home, but I'll post more photos as I go along fixing it.
