C5 Brake caliper piston ?

[brans72]

I was wondering if anyone could measure there front and rear pistons on there C5 calipers? When I say measure this would be with the piston out of the caliper itself. Also anyone know where to pickup new ones or aftermarket ones besides the factory? Thanks Brandon

I have a set of front and rear C5 calipers that are in great shape and only have 11,000 miles on em' that I don't need if your interested... are you looking for the piston diameter?

Al already posted diameters...are we correct to assume you don't need the lengths, weights, etc?
