I picked up a Kirkey seat off cl for$50. 

Do aluminum shells age out like composite shells? I figure it will be ok for a Challenge car that isn't fast but then got to wondering. 

I have been searching on line with out luck and thought maybe someone could point me in the right direction.

I have never seen an expiration date on an aluminium seat. But your gonna want a back brace

Thanks. I didn't think they did but you know what happens when you assume.
