Grades of Aluminum for T-bucket chassis

[JMarsa]

My next project is going to be a lightweight Model A based autocross/track car. I'm researching if it would be possible to run a aluminum chassis like the Boyd Coddington Aluma-Tub (http://www.streetrodderweb.com/featu...08sr_alumatub/) where they built the chassis from 3/16 wall 5052 (I don't know the spec H32, H34, H36, or H38).



I'd like feedback if you feel this alloy/gauge is sufficient for a sub 2000lb car and input on the grades or other alloy suggestions. I don't know the spec for the new ZO6 vette alum chassis but I know it's 4MM (.1574803 inch) which is close to 5/32 (the steel C6 chassis wall is 3MM). If anyone knows the ZO6 alloy spec that would help too as I'm sure GM has already done the math

Thanks,
