Trying to get my wheel stud situation figured out before my new wheels get here. With steel wheels I have roughly 3/4" of thread engagement. My plan for aluminum wheels will likely cut that in half because of the thicker mounting flange. I don't like this.
I ordered up some longer studs, but unfortunately these aren't going to work.
I'm having a hell of a time finding longer wheel studs for my front 44 that have the correct knurl placement and shoulder dimensions. ARP appears to make a set, but for $80 for five studs, no thanks.
Stared at my rotor/hub for awhile, and thought about how I could make a standard press in stud work (like what's pictured above). Snap gauged the ID of the rotor, .650". This is the largest diameter in the wheel stud hole.
What I'm wondering is, is there a reason to run the knurl .500" above the head of the stud on the hub flange? Why couldn't I drill out the rotor and hub to a common ID (.675"), and run the knurl on the bottom rotor side instead? For those not familiar, D44 outers press the rotor and hub together using the wheel studs. In this picture the lower step in the hole is the rotor, and the closest surface is the hub flange. It appears .500" of knurl length will engage the rotor and a bit into the hub flange as well, so they should still be pressed together.
Bad idea, or brilliant idea?
Anyone got a part number for longer front D44 studs (2" thread, 3" overall)? Fingers crossed SpecFab has what I need.
