good point! plus the 67" does look better IMO.

Unless you are just doing HPDE, the rules are what usually governs wing size. Typically the rules govern width, chord, height, position vs. the rear of the car, endplate size, and whether it can be multi-element.

Also, APR isn't the last word in wings, although others are often more expensive. Simon McBeath, a widely published racing aerodynamicist has his own wings (Simon McBeath - The Wing Shop) as does AJ Hartman who runs an aerodynamically extreme NASA AmericanIron/STU Mustang (Racing Wings). He has hired an aerodynamicist and has new wings and splitters just coming out. Also a rather unconventional view of canards with an additional one above the front wheel opening.

Thanks for all these information. I dont know yet if I am going to compete and which class I will be in. So I think I will just go big to get the 67". Can adjust it in the future.
