Benefits of wings:

1) Easier to drive - when you are talking about attracting racers from a different division or even getting a fan to start racing, making the car easier to drive is a big step.

2) The wing is not going to affect the life of the motor that much. The 305 motors I worked on never turned over 7600, and that only happened when someone hit you in the a$$ and you spun the tires. Its also 10:1 compression, so its going to last a while. Don't get me wrong, you can stuff 50 points of gear in it so you can turn it 7800 and try to wear it out faster, but the truth is you would run out of pull before you hit the flagstand.

3) New top wing is $600 and new nose wing is $125. You just have to put the rivets in it. That $725 is nice to have when you go for a ride, slowing you down and cushioning the impacts (better for newer racers).

4) MOST IMPORTANT - You have an extra 40 square feet of sponsor space to generate revenue to support your race team! (Wish it actually worked like that)

The 305 class is designed to save the racer money while being competitive. The wong should make it easier to drive, which SHOULD lead to less wrecks, which SHOULD lead to less money spent on repair parts. Even if it was $1000 for the set, its a wise investment.
