Torque specs on the lugs and strut Bolts?
I am going to install H&R springs on my g82 m4 this weekend and not sure where to find the torque specs on the lugs and strut Bolts that I will have to remove. Any help on where to look would be appreciated.

Did you ever find the torque values for the non-lug nut bolts? Strut nut, rear strut bolt, rear camber bolt, etc?

No but they were very tight to break loose by hand so I just made them as tight as I could by hand. The rear 21mm bolt was a little difficult to get out. Don’t forget to take off ride height or level sensor rod, it plastic so just use hands to snap off or a plastic tool

Not to split hairs here, but for my '22 M4xD, under the section called, "Changing Wheels/Tires", it states:
After the wheel change Tighten the lug bolts crosswise. The tightening torque is 101 lbs ft/140 Nm. Stow the nonworking wheel in the cargo area, if necessary. Check tire inflation pressure at the next opportunity and correct as needed. Reset the Tire Pressure Monitor again. Check to make sure the lug bolts are tight with a calibrated torque wrench. Have the damaged tire replaced at the nearest dealer's service center or another qualified service center or repair shop.

101tq for the lug bolts seems like a lot of force. Is this because they are bolts as opposed to nuts? And, do you recommend 'blue - Loctite' or not necessary?

Do not use Loctite. You may end up snapping a bolt off. In fact, I from time to time use a little anti-seize to make sure my lug bolts don't rust tight. Torque to spec with a little check post hard spirited driving is plenty fine.

Thanks for to Limegrntaln! I've been looking all over for this info and the dealer didn't know either...
Per the owner's manual .pdf from https://www.bmwusa.com/owners-manuals.html (Online Edition for Part no. 01405A37FC0 - VI/21), on page 346, it states: The tightening torque is 101 lbs ft/140 Nm. Where are you guys seeing alternate values? Is there a consensus that on the G80, it's 101 lbs ft/140 Nm? Link to screenshot of page in manual: |

It would seem the page numbers are different from model to model. This is my 2022 G82 xDrive by VIN number. My original post, I didn't have my car, yet, and it wasn't recognizing my VIN # as being built yet, so I used a VIN from cars.com, for a 2021, to make sure the VIN was recognized. For my car, its on page 344
