Hello!

Will 944 hubs fit directly on 914/4 ? Front and rear ?

Example 477 501 605 will they fit with no modification ?

I know that the rears will change your offset out further making your brake rotor to caliper alignment off. The rears do work in the rear bearings, as long as you use 86' or newer 944 hubs. (you will need a 5pm spacer ring to put on the 944 stub axle)

This is all assuming you are using 100mm cv's and machining your 914 axles to fit the larger cv's.

So NO. Not bolt on.
