Hello to everyone!
I was checking my spacers and wheels torque after the mechanic mounted them (with new tires).
I checked the torque setting on the manual and it's INSANE!!
150ft/lbs?? 204Nm for metric measure??!!!
I called a wheels producer, the spacers producer (they produce the studs for Eibach) and the mechanic and all of them told me that this value is really strange and strongly recomended me not to use this torque!!!
All of them told me those facts:
-This is a torque for large and heavy trucks.
-There is not a single sport or super car that use this torque, also Ferrari, Lamborghini (and we know them very well here in Italy) or Porsche, with 14mm studs, or motorsports cars, don't use this. The average torque is 100ft/lbs, just like previous Mustangs, including Shelbys!
-They say that it's impossible to use spacers with this torque, they surely crack, and even if I told them that many of you use 150 for wheels and 90 for spacers, the fact is 150 is the torque on spacers' studs! so this is pointless! In addition to this it has no sense to torque spacers and wheels with this difference; spacers has to be torqued to 10% less that wheels. 90 for spacers is correct.
-The studs producer says that this is almost the physic limit of the steel studs, you can torque in this way one time but after 2-3 times you'll have damage.
-This is pretty much the only car on the world that use this torque.
-The 99% of tire repairer or mechanics that use air pistols to torque the lug nuts are calibrated around 90-100ft/lbs, this is the standard torque of those machineries, and I can't believe that the most of 2015+ mustangs around the world are going to loose their wheels because, frankly, the owners that check the torque on their wheels are absolutely a minority.
So, can someone give me a clear explanation for this crazy torque??? someone in Ford maybe? an ingeneer would be great!
Thank you in advance!
