I bought the stainless ones from Bavarian thinking I might have a corroded one but I didn't. Just the seal was leaking. These pistons are in good shape. Came out of my 1998 M3. I have all four. No pits, just dirty. I'll clean them up and try to take pics if they don't sell quickly. That's lazy, eh? :) $20 for all four + 8.00 ship. If they are not what I say they are, I'll refund payment and shipping.

Thanks,

Jeff
