Coming from Noble(s) & taking delivery of a CSR 260 on Saturday, I have noted on the Gassing Station, the apparent lack of downforce on Caterhams.
My question being, surely that could be added to by fixing an adjustable blade off the top of the
track-day roll-bar. Has anyone attempted this, or is the projected height of such a negative factor ?

My first question would be why? The top speeds of 7s are not that high and the grip levels are excellent due to the low centre of gravity and proportionally wide stance (especially in a CSR).
Edit: as for doing it, Caterham did have a front chin spoiler on a car but no rear one and declared that it made the car far too pointy - I did wonder then why they didn't just add a rear spoiler as well to see what the effect was.

You need to readjust...My question being, surely that could be added to by fixing an adjustable blade off the top of the

The 7 is not about aero, it's about pure, raw, unadulterated handling.
Get it flat floored (with you in it - cars are badly set up out of the factory typically, unless you love understeer) and spend some time learning to get the most out of it. You will almost certainly find it's plenty quick enough round corners to avoid slapping tea trays on it.

IIRC the Elise comes in a gnats under 0.6m^2, a Seven is about 0.63ish. One was designed in a wind tunnel, the other in a shed. Not much difference, and ultimately real world results tell us the same thing, similary powered 7 and Elise have about the same tops speeds.

Quite a large chin-spoiler and rear diffuser, pretty odd looking.
