Dave,
Feel free to quote away... ;-)
Rob,
Thanks; just calling it like I see it.
Matthew & Ex-Racer,
Both of you seem to feel pretty strongly that a diffusor is simply not needed for a car with this horsepower level. Serendipitously, there is nothing in the rules that mandates a diffusor, so you are quite welcome to build your cars without one. Please keep in mind that this class was conceived as a "cost effective" class, not a "rock bottom cost" class. If you are looking for restricted rules that outlaw diffusors and wings with reduced power, then you really need to take another look at RobLav's post about F600 and the three-pronged approach that F1000 happens to be the middle of.

Matthew, your knickers are all twisted over some perceived injury - man up and re-read the posts at face value. Nobody was being insulting or arrogant towards you - the 6 posts comment is in deference to the fact that we don't know you, your history, your involvement in the sport, or anything at all really. The guy informed you that this concept has three different paths, one of which involved 600cc engines for tube frame cars with no aero, and happens to mention his opinion that this F600 concept sounds like what you're suggesting, and you jumped down his throat for being a smarta$$. Get a grip.

Cheers,
Rennie
