Just what the roadster needs

[leroybrown911]

I will defo be getting one of these when I get my bodywork, any ideas on price yet?

[vmax1974]

i will have one of them too

Finally something i know anything about

in order to get the ground effect you will need to break the airflow up by adding a vertical lip to start the air swirling towards the undertray then the fins speed the air up pulling the rear end towards the floor

Vortex generators,also fitted to aircraft wings !!!!

That could easily be added at this stage, i will look into it during having a few beers on Sunday.

I was planning on doing a rear defuser out of carbon fibre.

Will this fit with the rear panel section that was made by Triton? Our car is fitted with the full Triton body panels which we purchased back in 2008, we had a few extras done at the time which Triton intended to put into production but don't think they did so it makes our car rather special.

This might sound like a daft question, but how fast does a car need to go to gain any appreciable effect from aerodynamic aids? I.E. Is there enough gain for road use, or is it more track related?

should have a small effect on the road but the real benefit will always be on track and on motorways and as spud said the rear panel will not act as an airbrake to slow the car down other things you could do is some vents in the top rear of the rear arches to unload the pressure build up in them that will reduce the airbrake effect too so should also help with fuel costs

Caterham spent a lot time and money in wind tunnels on this very subject a few years ago. I believe the model that uses the findings is the CSR version.
