its pretty funny i tried the big front wing like you have northy at my tophy race i had last weekend during practice and it got really windy for a litttle bit during one of my practice run and it felt like my car wanted to fly off of the jumps because the wind caused it to feel like it was floating...haha
it was the wierdest thing.. but when it wasnt windy the car felt good with it on.. but i took it off as i needed more rear traction than front.
