There's a couple of options that spring to mind (found on this forum) if you wish to retain the macpherson strut design.

Firstly there's the ford XF disc conversion using 180B\200B\Stanza size stub axles
aca18t's conversion

Then there's the holden disc converion using S3 bluebird struts and holden discs and brakes. I forgot the specifics of what Chris said so best to ask him
Rockon's profile

otherwise you could do the silvia\300zx\r32 gtst style knuckle conversion and use those parts.
