Porsche 944 spindles have about 1 1/2 to 2 degrees more positive camber
than the stock VW spindle, this is where the problem lies (in the design).
There are several things that you can do to over come this problem. The first thing to try is
Topline's kit called
Camber + that will give you and additional 6mm of camber adjustment. If that doesn't do it then you'll need to slot the upper hold of the strut to spindle mount (see a Golf or 944 strut for an example of how to do it). Also, if the spindle can be clearanced to allow the strut to seat farther into it (see pic attached).
