F30's M14 lug bolts take 103 lb-ft.

I didn’t have the right deep socket for my torque wrench until today (Sol uses 19mm, F30 17mm), and I realized ALL my lugs were undertorqued, all weren’t even close to 80, and I was driving around looking for that socket, Home Depot didn’t have any. Still Code Browning here.

Every single time I work on my car I always have this tingling feeling for a few days I did something wrong despite checking a bajillion times, and this time rightly so.

The Hobo Freight wheel saver impact sockets are pretty good

Ended up going to Princess Auto down the street and found it. Retorqued everything with my good ol’ beam torque wrench and it’s all good now.

103 lb-ft

That’s... oddly specific. Sounds like the number I’d choose if the spec was, say, 95 to 110.

Princess Auto is basically Canadian Hobo Freight.

Chosen using science to provide the desired clamping force with the bolt size and thread.

It’s probably a metric conversion.

Yup. 140Nm.

Yeah, pretty much.

question: so I was lazy and didn’t torque my wheels today when I put them back on. Can I torque them without lifting the car? Just loosen one lug a turn or two and torque it. Because I’m lazy and don’t want to lift the car again.

Doing that is better than not torquing them at all. The “proper” way is to lift the bulk of the weight off the tires though.

I thought the final tightening is actually on ground, unless you do it with an impact with torque limiter bars.

I always put wheel on, hand tighten, lower car then torque in cross diagonal.
