On my E36 M3 front calipers, how would I know which stainless piston to order?
These guys list them as ate10, ate11, ate12. Where can I found out what size my brakes use?

Care to share so others in the future will know?

In the beginning I hadnt set the drop down menu to be "E36....M3...96 and up" so thats why the 3 options of pistons came about.

IF you set the thing to filter results to the correct car it works fine and gives you part number "ate10"
