Hi,

new member here looking for your input on low lift and low drag aero ideas for my little track car (awaiting prep when i finish uni for summer)

Being unable to make the car longer rules out boat tails/ large kamm back extensions/ nose extensions like basjoos' civic. I doubt front wheel skirts or flat wheel trims would be possible either as the front brakes in particular generate a lot of heat on track.

Im thinking along the lines of:
small roofline extension/ small kammback similar to

and Piwoslaw's 307

flat undertray and side skirts- perhaps with VGs on the undertray

front splitter

possibly perspex rear wheel skirts

aerial/ rear washer jet and sunroof will be removed

extension on the rear of the bonnet to deflect air around the wipers as per http://autospeed.com/cms/A_2445/article.html

passengers side mirror delete or replace both mirrors with smaller ones

possibly sealing off the high pressure cowl intake in front of the windscreen or using it as place to have the air intake for the engine.

Venting under-bonnet (under hood) air out of either bonnet vents, a vent in the undertray or out the wheel arches, which may also help brake cooling.

Thanks for reading, I would appreciate any suggestions, feel free to flame any of my ideas
