Anybody ever use these on there car? I know there are not the top performance parts but I am going budget for now

 

C6ME-6110-A 410 piston
410 casting
4.050" std. dia.

Anybody know if these are quality as well?

 

D2 & D8 is 72 & 78 stuff .. as you say not the least bit good for performance but good steady workhorse stuff . iv`e never heard of a 0.50 over piston .but still if it is factory stuff have it measured to check for wear ..measure the bottum of the skirts as that is what wears the most from flopping around so much in the bore .and measure the bottum of your cylinders ..
