      This is a 3 part question. First, does the size of the bite bar make a difference in the way the car handles in both Flexi style chassis 

and Retro chassis? The second part of the question, is piano wire an acceptable material for a Bite Bar. The third and final part of the question, is this a stupid question?

Ditto above.

Perhaps this is the answer to your next questions:

Smaller diameter bite bar will make the chassis more forgiving (less nervous) all other factors being the same (track, grip, tires, chassis material and thickness, weight, etc.). There is a point at which chassis will react slower if the bite bar is too flexible.

Essentially you are controlling pan movement, whether via air gap or flex. It can additionally change how a rail combination twists and even regulate downward rail movement off corner. Smaller bite bar more flex or more movement which typically equals more bite. Larger diameter bite bar restricts pan movement and frees up the car.


With regards to limiting and adjusting pan movement, you can use leadwire sheathing slipped over the ends of the bite bar, however make sure it doesn't allow the trailing ends of the pans to sag below the center rails. Ill do this at times when I am happy with the bite bar diameter, but just want to reduce a little movement.
