2006 Z4 3.0si----Standard rims----Proper torque for lugs?
In owners manual under Tires--changing or somthing like that.
Except--as in this case--when the OE tires are run-flats, in which case the owners' manual omits scary, confusing and useful facts like this.
On 14mm lugs 120 Nm or ~88.6 lb/ft - dry as in no lube on threads. Most folks torque to 90 ft/lbs. because it's easy.
According to Cain BMW, correct torque is 80 ft/lbs.
