lug nut torque

[JL1958]

I have tried running a search and reading my build manual, but I can't find lug nut torque specs.
I have 15" Halibrands with a 4 bolt pattern.
Thanks.

19 views and no replies so either 1) it's top secret, or 2) you're wondering what kind of goober has a custom car and doesn't know this basic info?
LOL!!
Okay, I'm a grandmother who has an afinity for hot rods, give me a break!

Hopefully someone will know for sure.

I am out of town and can not verify, but I thought it is listed with the Halibrands wheel shipping info (not the build manual), if they are the ones sold by FFR.

JL1958,

One of the things I'm finding out about the driving phase of this project is there is no back up! So when I forgot to tighten one wheel (had it off for some reason), it will result in damaged lugs. I had to replace them which is no fun (first you have to get the old ones out). So now I tighten the lug nuts whether the car is on stands or not with an impact wrench. With my large compressor that brings the torque to about 80 to 90 ft lbs. The I take the 1/2 inch torque wrench and follow a star pattern (5 bolt) until I have all at 100 ft lbs. I like the clicker wrenches as it is easier. Then I repeat that a couple of times. On yours it would be an X pattern you follow. I don't know what your background is but if you don't have some of these basic tools or someone in the family who does, you will 1) have to rely on a good mechanic or 2) build up your inventory a little. If you visit a Cobra owners garage, I think you will get a much better idea. I have friends who have garages that look like a professional one and others who get by with the minimal. But I am getting a two post lift so life is good. Good luck, WEK.

I have the PS Engineering 4 bolt. I use 85 Foot Pounds.

I have a torque wrench (clicker type) as I have done some basic maintenance.
I just didn't want to over torque the aluminum wheels and couldn't find any info.
Thanks everyone. I will check set it at 90 and check all of them.

My C3 Corvette with Al wheels is torqued at 80 foot pounds, so 80 to 90 range sounds right.

Regardless of vehicle, I would also recommend going back after driving for 20-25 miles and tighten the lug nuts again with the final torque, just to make sure they are still tight. It might be a little over the top, but better safe than sorry.

I have the PSE 4-lug wheels on my roadster and keep them torqued at 90#.

80-90 pounds covers nearly every regular car w/ 12-14mm or 1/2 inch lugs. Here is a really cool tool of those of us who do a lot of tire swapping. The set

Or they can be bought individually. Also available is an accutorq extension so you can use any socket on it.

We started using these at Lexus about 15 years ago and haven't used a torque wrench since. The technique w/ your impact wrench is to slow spin the nuts on so they just contact the wheel and allow any centering that is needed to happen. Then go around again giving a second or so of full blast per nut. Fantastic tool!

Seriously?!? That's cool.

[JL1958]

Seriously?!? That's cool.

Well, I'm not your average grandmother, but yes, I was told I was cool by the young man at the Speed shop Saturday. Actually he said "it's cool you own this car. We don't see many old ladies in here." I was cracking up inside, but was nice as I could see he seriously thought it was a compliment. LOL!!

Rock on!

I'll second Craigs answer or just go 85 ft lbs.

I hate on our daily drivers when I have to pull a wheel that has been completly over torqued at the dealership.
