I am not sure what vibrating parts you are talking about here. The chassis
should have no movement at all and you can easily check it for torsional
rigidity. Carrol Smith wrote a whole series of books on practical race car
construction. They are still available through Amazon among others. The only
compliant parts that I am aware of on a race car or bike for that matter are
the ,spings,shocks and tires. If and thing else is deflecting due to chassis
loading it needs to be fixed.
