Default Torque specs for IS350 2014+ (mine is a 2016)??

I'm feeling some vibration in my steering wheel after 60+ mph and I just had 20mm spacers put on last week. I think it may not be torqued evenly.

Does anyone know what the torque specs are? Is it the same as the 2013 at 76lbs?

I torqued mine to 90ft lb no problems.

Do you have spacers on yours? Any issues with vibration at higher speeds?

Except stretching the threads beyond spec and wearing them out faster.

Same specs. I hope your spacers are hubcentric cause if not, there's your culprit!

Aren't the specs 80-85 +/- 5? I doubt the studs would damage or excessively stretch with a 5-10 lb over torque. Otherwise every Lexus that went to an American Tire or equivalent would be damaged all across this nation. And believe me there's a LOT of those.

In the BMW community, it's common to overtorque wheels by 10 lbs for track days

Personally for any car, just go with what the manufacturer recommends with a calibrated torque wrench.

76 from the Owners Manual. Why not use the recommended setting? And yes I've had to buy new lug nuts from over tightening, granted a race vehicle that had wheels changed often.
