All right, stupid question. What the heck is the torque spec for the wheel lugs on the '86 951? I looked on Clarks and in my factory manual and can't seem to find it anywhere. Where the heck did is it again?

For some reason 120 N-m (+/- 96 ft-lb) comes to mind. . .

Confirmed, Haynes says 96.

im a tech insp. for PCA and we do 94-95 lb/ft on all p-cars.

Thanks guys.

Do like the tire shops, if all else fails, use 150-175 ft*lb

...but only on one lug nut. Remember, no anti-sieze or lithium grease either, wouldn't want them to back out on you.

Haha, I see you've had your tires changed at Wal-mart too!

They tightened one lug nut so tight I had to use an impact gun to take it off, and the other 3 came off with a short-handled socket wrench...

I always tighten to 96lb/ft, and it seems I have been right on

I went down to re-torque them and DUH! Guess what? My torque wrench still had 130 N-m dialed in from the brake job on the 944 a week ago. Figures. I could have looked at that and saved myself the trouble, but it's good to know it's the same for both cars.

When I have my tires rebalanced I give them my soft socket, tell them 95 lbs, I want them to use a torque wrench and if they strip an aluminum lug nut they are only available from Porsche as a set that costs $130.

What they don't know helps me.

im not that trusting, i take the wheels off, throw em in the truck and take em to the shop.

You sound just like me. I even do this on my other cars, between the warped rotors, stripped studs/lugs, and leaky oil pan plugs I avoid all one-stop service centers like the plague.

Absolutely good advice.

Any outfit that makes their profits on bulk is trying to keep costs down by using the cheapest labor possible - that means the local high school dropout that's got delusions of getting sent to "mechanic school" on the shop's dime usually is the guy working the balancing machine and doing stuff like tire rotations that they're not going to waste a more highly-paid ASE mechanic's time on.

I think there's also a difference in torque-specs between a steel vs. an aluminium lug-nut as well...

Shouldn't you back your torque wrench down to 0 or at least a low setting for storage??
