Hi John,
Very true indeed: stock front disks and 944 n/a rears on stock MC is what gave me rock hard pedal and awesome brake balance!
In fact, liked that so much that for my 'daily driver' project, I got a set of fresh stock sized disks in 5x130 from CB, because I liked the alu hub a lot. By now I have acuired parts for a rear 944 20mm disk set up (vented/drileld of course
) as we, so I'am close to the swap :-)
Here you can just see (through the rim) the also new, drilled, 944 n/a rotor bolted to the rear IRS hub:
