Brake Caliper Brackets - what material?

[TeflonT]

Seeing as I have already made these, someone mentioned making them from mic6 is a bad idea. Is the material up to the job? http://www.alcoa.com/mill_products/catalog/mic-6.p...

The brackets are quite chunky adapters (18mm thick at thinnest point, 30mm thick elsewhere) between an Ultima type ProSport hub and Willwood Superlight 6 pot calipers. The uprights are LM26 and the lugs only 12 x 30mm cross section.

I wouldn't use a cast plate for something like that, especially if you haven't used a thread insert for the fixings (cast plate is not great for holding a thread). Personally, I'd pick something like 2014 (aka HE15)

Just finished these, Billet 6061 is the only way for something so crucial... Over spec is best for this I think....
