Cast Chassis and coefficient of expansion of steel and aluminum effect on steering geometry

[Yperformance]

Hi, was getting board so thought I would try a new topic. Since aluminum expand way more than steel if you have an alignment done on a cold day will it be out when driving on a very hot day? Will it effect the way the car handles? My guess is that a 50 degree heat change will be about 1 mm across the chassis.

Um. I don’t know. I’m far from an engineer, but with the expansion being equal in all directions, I wound think the answer is no?

Mmm that would be true if all distance s were equal in all directions.

See? I rest my case!

The more I think the more you are right
