Pullbar angle?

[Confused?]

About the angle, the same basic principle applies to a solid bar. One thing to remember, the more angle, the more UNloading at deceleration. That's what causes wheelhop when getting out of the throttle.

I think the reason why the myth comes about when people say it "runs out of traction" is two main reasons. The first being the spring softens the hit on the tires making mid corner feel better to the driver. The other reason being the spring collapsing under load changes the anti squat characteristics at mid corner till the weight of the car catches up with momentum at about mid straight and the spring expands again changing the Anti-Squat characteristics. It's a dynamic thing that gets removed with a solid PB. Basically put, the solid PB doesn't allow the axle to wrap up and soften the load on the tires till mid straight. You can do that with your foot however.
