wheel nut tightening torque - is it really 470 ft/lbs?
I was at Discount Tire getting some tires for my 911, and saw on a sheet that the Carrera GT's wheel torque value was listed at 470 ft/lbs. Is this correct? I'm just curious, and I figured you guys should know!

I was actually told by the mechanic, because the locking tabs weren't clicked out on one of the collars, that you use the torque multiplier and with that you can use a regular torque wrench. Dunno how much truthful that is but I am sure the manual would cover that.
A = Length of adapter needed, in inches
Ta = Required torque at working end, 407 ft/lbs.
Tw = Torque wrench reading from its scale, 250 ft/lbs
L = Length of torque wrench, from handle center to drive center, 18"
using my large torque wrench I'd need an 11.3" extension :
