Any information?

I need to purchase a new clutch master cylinder for my brother's S1 3.8 car. There are two options available: a cast iron one and an aluminum one. Does anyone have information on whether one is superior to the other? Thank you.

I'm afraid I can't help on this, but looking at your username - you don't make radiator fans do you?
No offence meant, good to have you on the forum
