please fix my confusion x 2

ok here we go
i have read all through these forums about how people spend ages straightening their new chassis to get them to handle and work well but what confuses me is that to get my cars to sit as close to the tracks as i can to make them work and to do this i get the pliers out and bend and twist the front of my chassis to get it to sit low and handle and doesnt this make the chassis bent again???
or am i doing it wrong......mind you the cars handle well and i am getting faster all the time.

next cofusing thing
breaking in motors....
i have just purchased a new Falcon 7 and installed into my cheeteh 7... should i run the motor for 10-15 mins with no load to break it in or just run it at the track slowly for a few laps the thing that confuses me is people say these motors have limited life so if running them in doesnt it reduce their life....

just interested to know what others think

flattening, not straightening, chassis' would be the proper term.
Most production chassis' wont be flat from the manufactuer (most non flat/square bits are common to all new chassis' from that manufacturer).

a new motor will be a tad quicker if run first to radius the brushes, but yes it will shorten the running life of the motor. So if you can afford to go through motors quicker, do it.
