A few question for you q45 dif users

[SxMachine]

Done a little research before I complete my q45 dif swap. So far after crossferencing these posthttp://forums.nicoclub.com/zerothread?id=426226http://forums.nicoclub.com/zer...nticahttp://forums.nicoclub.com/zerothread/267924

Im curious if anyone has had issues with their ebrake setup before and after the install using the q45 rear, hubs etc. Also I plan on upgrading my brakes (q45 front, z rear) with z mc. Altho i dont foresee any issues I'm wondering also if anyone has had bias issues or could see me having issues with a mismatched brake upgrade. Thanx
