Like I mention previously...I found the link to the article of the Formula Student Chief Design Judge, where he stats that suspension layout is more important in the F. Student. Another thing is the idea of the F. Student is to design a car that is Marketable and that costs under $25000 US....well using wings will bring up the cost of construction, will add weight and the adventage that it brings might not be as much as the disadvantages........you can lose points in the design/market parametres and not gain the lost points in the dynamic categories.
I'm not saying they don't work...I'm just saying in a F.Student kind of aproach they might not give you the edge......if I built one for personal use at I'd include the wings.....but in a F.Student way i wouldn't....it would penalise the team in the marketability/costs parametre....and the time lost due to the dseign of the wings can be used in a further detailed suspension design...which might give you the edge...that the wings might not give.
The famous Carrol Smith, previous judge, used to say that aero was importante......well....2 diferent engineers....one from the old school and another from the new school......i agree with both.....but for me suspension......has a slight advantage (in F. Student terms).....but it also depends on the circuit that is used.....I say a video of the F. Student and the race was held at very slow circuit that basicly consisted of chicanes....and slow hairpins.
