If you use mk3 16v hubs and ball joints with your existing hub flange, you can go to 288, it does mean having the discs drilled to 4x100, I don't have this issue as I'm running 5 stud, but the reason I went for this setup is that you only need a spacer made and you could go 312mm on the mk3 16v/vr hubs.... However there is plenty of stopping power with the 288 & mk3 master cylinder... I only have to breathe on the coward pedal an it pulls up hard...
