Any nascar chassis builders on here or people that know the process that they use for their chassis?
How many do they build during the yr ?
What material is used ? and size ?
Just a few questions to get the motorsport forum going?

Rich,
Good question.
NASCAR tightly regulates the chassis and materials. The chassis are mild steel tubing. The sq frames are .120 wall and the other tubes vary from .065 up to .090 1 3/4 tubing depending on where the tube is located and how critical the tube is. Most of the main safety tube is 1 3/4 .090
The cars can be TIG or MIG welded and each chassis must get inspected by NASCAR before it gets a ser# and is allowed to race. Most of the suspension parts are TIG welded. IE: upper and lower control arms, shock mounts, spindles etc.
Check out some of my pics from Daytona.

Andy,
Could you touch base on what, if any, NDT testing process that are performed on the chassis.
(Just trying to keep the thread going.)
Regards,
Scott
