VW Front Discs + 944NA Rears? (on a 1303)

[WD-40]

Heya.

I've been doing a lot of reading and a lot of searching. I've found a few references to this particular setup, but nothing involving too much detail.

What I'm considering doing for my 1303 is using the front disc brake kit from CB for the front (basically VW, but studded to the Porsche pattern), and the rear vented disc brakes from the NA Porsche 944.

It seems like it would have a lot of advantages:
* lighter weight up front for better road handling- many remark that the front 944's are overkill, and HEAVY.
* Rear swap is brutally easy, and way cheaper than any aftermarket disc setups.
* Rear track is increased (I want this) while front is not (or at least, very minimal).
* Front is VERY cheap to do.
* Very few "custom" parts overall. (no new ball joints or billet hubs)
* No camber issues (like 944 front spindle swap).
* almost all friction parts are off-the shelf and easy to find if you need them.


I already have the full 944 brake set... but am considering the above plan instead of the 944 fronts. The only thing holding me back is that I don't know how the proportioning would work out, and what master cylinder would work the best. I don't know the formulas, and won't endanger my life by pretending to know what I'm talking about when I don't.


So someone please tell me why this won't work... or better yet, tell me why it will! This is one of my last big hurdles with this car....


Thanks
