Has anyone used a 52" axle when racing with a wing? What would the effect be? I know wing guys use a 50" axle. Just wondering if there is any disadvantage by running a wider axle.

Makes the car tighter.

I agree with the above makes the front not bite so it pushes and feels like its tight. Tried it. And your not going to go fast with that in the car. There a reason it's not on Woo cars doesn't work and the one time it might you'll never find.

The thing people tend to forget about wings is that the faster the car is moving the harder the rear end is stuck to the track and the lighter the front end is.... so at the end of the straights, right when you need to start turning the car, you are getting max rearend downforce from the wing. Without just cowboy jacking it in and killing your momentum its fairly difficult to get a wing car to enter a corner smoothly and hit your marks precisely, and adding 2 more inches to the right side of the front axle is just going to make the car less interested in changing direction.

With a wing car you have a whole box full of new set-up compromises you have to make. The slowest part of the track, center to exit of corner, where you are adding throttle and trying to get the car to accelerate hard and straight, is where you need the aid of a wing the most and that is where it is doing the least amount of work. A wing actually hurts performance on the straightaways and corner entry due to drag and thats the part of the track it is doing the most. That's why the asphalt supermodifieds have the nifty air cylinders in the rear wing tree. It lets the wing flatten out to minimize drag on the straights and stand up tall thru the corners to increase grip.

If the last spare in the trailer is a 52", mount it 1" to the left. It'll only be half as screwed up and you can still get start money.
