Semi Metallic Brake Shoes - 11 in Drums

Anyone know of any 11x3 (front) shoes available in semi metallic?

You might check eBay & Google brake parts suppliers (esp performance ones).

I've used the carbon metallic and straight metallic before; and still have a set up in the attic. they don't work very good cold. they like heat and would work much better with a power assist. they don't fad and the ones I've used didn't seem to be prone to lock-up.
