Stumbled on this new gem that just came out recently. I actually talked about something like this before this came out. No more swollen plastic rotors. stainless steel water pump rotor. I have no issues with my water pump at the moment but this is just insurance down the road, so I will be installing this when I complete my cooling system upgrade.
Was wondering about as well. I see an aluminum one that doesn't look polished on eBay as well. Tempting.
