P3D-R
Closed
I have measured at the stud itself and seen a 5mm difference in engagement. I didn't base measurements off that protrusion at the hub. Are your ET's open ended lugnuts? If close ended just gotta make sure the stud doesn't bottom out inside the head of the nut.Well the 3P has that lip due to the thinner rotor hat. That lip is just under 3mm. So that means you have almost 3mm of extra lug sticking out vs the non P cars. So technically you can put on a 8mm and should have enough thread to tighten 7.5 turns with the stock lugs. I will be trying this tomorrow with an 8mm and 10mm slip on using stock and ET lug nuts on my 3P with the 20" Ubertines.
