Very good choices i must admit. One issue for me though ( im going the same way for my street 1303)

The position of the front ing vents
A: the J-sports racing bug has 2 cuts on the back side of the wings

B: F40 used a huge vent on the back plane(vertical) of the front wings

C: DTM Audis and 935 have vents on top of their front wings. From what i have read on the DTM cars is that the vents on top of the wing help the above the wing ( low pressure) get filled with the vented air from the wheel wells...

D: the best i believe would be the 911 gt1 design


I also agree with the front bottom closing every posible gap (air trap)
