Just as posted, what is the proper torque that the lug nuts need to be on a 2000 Boxster?

Stephen Tinker

130 Nm (96 ft/lb) for each nut.... make sure the wheel is on the ground with the weight of the car on it.

Just to add I like to go snug the bolts up with a regular wrench - just enough to hold the wheel securely against the hub when the wheel/tire is lowered to the ground -- then once the car is on the ground go around with the torque wrench set to about half the final torque setting, then around again at the final torque setting.

Be sure too to follow a 'star' pattern in tightening the lug bolts.

Sincerely,

Macster.

And if you have wheel locks, those should always be the first bolts you loosen and the last ones you tighten/torque.

Oil the threads and under the head of the bolt, but do not oil the cone section.

I would not use oil, I do use a thin coat of anti-seize.

Early on I replaced the wheel locks on my Boxster with just plain bolts and intend to do this for my other car too but I keep forgetting to order the hardware.

Do not torque the lug nuts or bolts to 130Nm if oiled or anti seize is used. The nominal 130nM is for dry bolts, if the threads are lubricated 130nM might cause the bolts to exceed their yield strenght.

I have always used 85 ft/lbs with my thin coating of anti-seize on both OEM aluminum lug nuts & Box bolts

Macster

Uh, no that is not correct based on my references.

The 130nM (96ftlb) torque value is for bolt threads treated with a "thin coating of Optimoly TA (aluminum paste), on the shank, and between the bolt head bearing surface and the spherical cap ring (under the head). There is a caution: "Do not grease the spherical bearing surface of the wheel bolts that faces the wheel!"

Sincerely,

Macster.
