i know traction bars help with traction but im not sure how was wondering if anyone knew how

 

The bars prevent spring wrap-up under heavy acceleration.
When torque is applied, the tire grips,
the spring actually becomes an 'S' because the pinion is climbing up the ring gear,
the tire loses grip, the spring unloads and the wheel hops.
The above is looking at the Camaro from the side.

If you were looking from the rear and under the same torque applied,
the differential wants to rotate CCW, this reaction 'lifts' the pass tire losing grip,
sometimes violently as it repeats the wheel hop.

Traction bars take the rear axle rotation from the side view and and applies the reactionary torque against the front spring eye and transfers the torque.

Newton's Law - for every action, there is a reaction.
You're always fighting the reaction.

 

Just a note; no traction bar will totally eliminate tire spin if you have enough HP. But as Everett mentioned, it's wheel hop and spring wrap that increases traction loss, so stopping those will significantly increase tire hook up.

 

they help keep the rearend planted on the ground and minimizes the hop, but traction depends on road and tire conditions

 

Cal Tracs work very well, our experience anyway.
