Nice.

I don't know how I missed that racetrack video (above), but I enjoyed it this morning.

Cheers,

Made a splitter and diffuser for the car. It's unknown what the impact is but I can still get the car on and off the trailer and nothing fell off at speed at the track. The design was short of borrowed from a Caterham blog http://csr200.blogspot.com/2014/05/rear-diffusor-and-front-splitter.html. Either way I had never made anything from carbon fiber before. Design is a carbon / foam sandwich, splitter is a pound or so and diffuser around three, seems pretty light for what they are to me. Including a couple picts of the mounting system and a pict of my high tech splitter deflection measuring system. Vertical section of the splitter is aluminum glued to the carbon with six ten epoxy and a wrap. Rear diffuser mounts are two piece so they don't stick out when the diffuser is off. Should have an aeroscreen done soon.

Made a foot rest. If you look closely you'll see the new aeroscreen as well. Will be at NJMP Seven's again this year to give it a whirl.
