An interesting development happened to me a Bylton. On the way home I noticed that I had a vibration coming from the front. worried that I had damaged to brakes or discs I checked things over. Even although my front wheel nuts were torqued up to Toyota recommendations all ten were only finger tight. The more than normal massive forces placed by track driving on the front wheels must hve been enough to loosen the nuts causing the vibration. This had never happened to me before. I'm upping the torque settings next time.
So if you have not checked over your car by now do so.
