Bill,

So you consider front S4/993 n/a (med. caliper) over 304 mm. rotor & rear 964 C4 caliper over 299 mm. rotor as a viable mix, assuming no bias valve ?

Bill Verburg

It's way out of my comfort zone. 964 starts off as the most front biased of any n/a 911 ever made by ~ 7.7%, by just making the change to the 993 calipers you are increasing the front bias a lot.

To get back to the norm for 911/930 you will want the 993 rear calipers. And yes even remove the p/v.
