On my k10 I fitted k11 hubs. Iirc the steering ARM on the hub is about 10mm shorter, giving slightly quicker steering!
What I have planned to do but not got round to yet. was too cut the ARM and shorten it even more. Like another 10mm or so.
I was gonna flip the trackrod end so the nut was on top instead of below. I was gonna do that to dial out some bumpsteer!
Iam defo doing some new hubs in the next couple months and ill be making a jig
