Why was this car bouncing?

[pinecone123]

Hi Everyone,
I was watching another pack's race and the car that won was bouncing back and forth on the rail throughout the race. Seemed like the whole car was evenly going back and forth. It wasn't the front that was too light and steering loose, or the back fishtailing either. It was evenly doing this.
This car was undefeated! My son's car will compete against it at the districts next month. Does anyone know what was happening here? Was it doing that because it was so fast (a trick?) or would it have been faster without "bouncing"? What would cause a car to do that?

Also, what is a good time for a 42" wood track?

Thanks You in advance for your answers

Greetings Pinecone:

My guess (and this is truly a guess) would be that the car had excellent axle and wheel preparation, canted axles, fair alignment, but extremely aggressive weight placement. Aggressive weight placement will exaggerate flaws in the alignment, especially with canted axles. This combination of factors could explain the "bouncing" and speed. Ordinarily, a car with the action you described would be slow. But if the other factors I described are present they could compensate for the alignment to some degree and still be fast.

I would never, purposely build a car to run like that, and I suspect that as fast as it was, the car in question would have been considerably faster had it run straight.

Just my opinion.
