Bolt head size

[Who's on first]

Anyone know off-hand what size wrench I should use to remove the wheel studs?

And or the torque values for replacing them ?

If I remember right 17mm, don't remember the tq values.

85 to 88 ft-lbs

Believe that was for the e9x platform. I think its something like 110-115 for the F8x, but dont quote me.

The F8X (as all other BMWs) don't have studs, they have bolts.

The head size is 17mm.

The Torque spec is 140N-m, or 105lb-ft.

That torque value is for the older generation BMWs that used M12 bolts. The newer cars use M14 bolts that require 105lb-ft.

And as tidbit, a ft-lb is a unit of energy, while a lb-ft is a unit of torque .
