Help...Fitment issue for w208 19's
if you are doing what I think you are you may want to read this ...
respected in the automotive industry and sent him to school... So I thought I would share this info. If he didn't know
I'm guessing alot of others wouldn't either.
Anti-sieze on a lug bolt is a very bad idea !!!
Here's why: Bolts or studs provide clamping force by being purposely stretched. Most torque specs bring a bolt well
within its elastic limit. Then when loosened they will return to their original length and can be safely reused (Some
bolts, including many head bolts, are purposely stretched past their elastic limit, and can not be reused). The torque
wrench is the most convenient-but not the most accurate-method of properly stretching automotive bolts. Engineers
spend hours correlating the proper bolt stretch to the required turning effort.
About 90% of a torque specification is used to overcome friction; only 10% of the specified twisting effort provides
clamping force. It is no surprise then that most lubricant tables recommend a 40-45% reduction of applied torque when
using anti-sieze on a bolt. So, a lugbolt coated with anti-sieze should be tightened to a maximum of 49 ft-lbs.
Tightening this lugnut to 85 ft-lbs. means it is now over-torqued by 73%! Considering that most torque specs stretch a
bolt to within 70% of its elastic limit, over-torquing by 73% will easily send the bolt or stud well beyond its
elastic limit-and could be dangerously close to its failure point.
For this reason I would suggest to all forum members to never use anti-seize on your lug hardware.
+1 for buying wheels that fit properly!

stock lug bolts are too long for the wheels. seems the bolts are going to far in and they are making contact with the ebrake. going to either grind the bolts down about 5mm or get some new lug bolts that are already shorter.
You dont want to run that car with the grease caps missng from the front unless unless you plan on replacing you front bearings after you get towed home.
Except of course if you plan on checking the grease weekly or daily and making sure no water gets into the hub. Of course that would mean removing the wheel..
If those wheels won't fit the grease caps on you should consider Luke's advice.
