1) I don't use OEM wheels, so I can't use OEM lug nuts (reduces the number of threads in contact)
2) I don't have factory suspension
3) I use wheels spacers on the front (with aftermarket lugs)
4) I drive agressively
5) I use anti-sieze

1) Does not support higher torque, and would actually be a good argument for lower torque. I broke my stud with a locking lug that had only 2/3 the thread contact of the original lug.
2) Is immaterial.
3) Is the most relevant reason for a different torque.
4) Is immaterial.
5) Supports LOWER torque, not higher torque.

Torque values are based on fastener stretch. Fastener stretch is based on the Young's modulus of the material used for the lug. In the case of rod bolts, the ideal way to install is to measure the bolt unloaded, then tighten until the specified stretch is reached. Some torque values are based on elastic range, others on plastic range (torque to yield). They're all based on the fastener's material and treatment.

Oiling the threads lowers the torque required to achieve the same stretch. Anti-seize is a lubricant on threads. All wheel specs are for dry threads. I don't trust dry threads, so I use anti-seize, even though I know it will stretch the fasteners more than Toyota expected.

Something to keep in mind - 76 ft-lbs is what Toyota recommended for the wheel lugs on the Supra, a 3500 lb car with 155 mph top speed limiter and a measured 0.98g cornering capability on a 300 foot skidpad. Unless you've measured the lug stretch or you have a specification from your spacer manufacturer, anything else is just a guess.

Lord, I cannot believe this is actually a 3 page topic.......torque your wheels to 80 ft-lbs on your IS350 and you'll be fine. That's what I've used on the stock 18's, the 19's, on a 1,000 rwhp Supra with 19, 18's and 17's and it's been fine.
