Wheel stud torque?

Anyone know the official wheel stud torque value? It's not in the manual anywhere.

Thanks!

125 lb-ft.

Apologies, didn't notice I'd strayed into the Gen 2 forum...

I think that is way too high. More like 80 ft-lb or 110NM. Should be in handbook.

80 lb-ft is for Gen1 NSX. 125 lb-ft is for the Gen 2 NSX.

Thanks Charles. Sounds about right to me.

lug nut*. wheel studs are pressed in, not bolted

The owners manual does not mention the torque settings for the wheel studs. I am running spacers from SOS and included were longer stud bolts. I am assuming the torque requirements are the same. It is listed here from Acura:

INSTALLATION
NOTE:
• This aluminum wheel is designed for use on a vehicle equipped with a TPMS (Tire Pressure Monitoring System).
• This aluminum wheel is equipped with a tire pressure sensor. See the service information for the tire replacement and tire pressure sensor installation procedures.
• The illustrations of the aluminum wheels are shown for reference purposes only.
• Install the correct size tire.
• Follow the instructions in the owner’s manual when lifting the vehicle and when removing and installing the wheels. Do not overtighten the wheel nuts.
Wheel nut torque: 170 N·m (125 lb·ft).
• Use a tire changer to install and remove the tires according to the directions in the operation manual furnished with the tire changer. Do not use a tire lever to install and remove the tires as it may cause damage to the tire and aluminum wheel.
Client Information: The information in this installation instruction is intended for use only by skilled technicians who have the proper tools, equipment, and training to correctly and safely add equipment to your vehicle. These procedures should not be attempted by “do-it-yourselfers.”

1. Before installing the tire pressure sensor, clean the mating surface on the sensor and the aluminum wheel.
2. Install the tire pressure sensor and the washer on the aluminum wheel and tighten the valve nut, finger tight. Make sure the tire pressure sensor is resting on the wheel.
3. While holding the tire pressure sensor against the wheel, tighten the valve nut to the specified torque. Tightening torque: 8.0 N·m (5.9 lb·ft)
NOTE:
• Check the grommet on the tire pressure sensor to make sure it is seated properly.
• Make sure the valve stem does not protrude into the sensor housing surface.
• To prevent the sensor housing from getting caught on the bead of the tire, install the tire pressure sensor so that the sensor housing does not protrude into the bead area of the wheel.
• Do not reuse a grommet, even one time, as it maybe deformed inside.
• Do not use pneumatic or electric tools on the valve nut.
• Over-tightening the valve nut can damage the grommet.

Install the tires according to the instructions in the service information.
Install the wheels on the vehicle and torque to 170 N·m (125 lb·ft).
Drive the vehicle for at least 40 seconds at a speed of 15 mph (24 km/h) or more, and all sensor IDs will be memorized automatically.

It is also recommended that you purchase studs that can be screwed into the rotor following removal of the wheel. I use two per rotor. This makes it easier to re-install the wheel. One must be especially careful if you have Ceramic rotors. Without the guide studs one could hit the edge of the rotor and damage it. They are expensive $thousands to replace. I purchased from Amazon.

This NSX uses Lug bolts?? Like euro crap? Boooo Honda. Hiss, boooo. shame on you. Lug bolts SUCK. Always have. You'll see.
