From what I read you are making an Evo 4 front hub. They can bolt on any brembo found on any year evo.
My brother runs them on his Evo 3. The only difference is the type of ball joint it takes, But thats why you would run Evo 4 control arms that are cast aluminum. I and also believe they use the same wheel bearings as 8&9 evos,

I haven't checked if they fit in 1g but it looks indentical. I should be trying this in a few weeks though.
