Bought some new Michelin Super Sport Tires, for my 2007 Z 4 M Coupe. Does anyone know / or where I can find, the Torque specs for the lug nuts? Thanks Rich
It would say it in your owner's manual. I'm guessing ~54 84 ftlb. The important thing is they are all the same and do it in a star pattern. {Merged threads}
54 ft-lbs! No way! (The only BMW's even close to that low are a minimum of 30 yrs. old...) http://blog.bavauto.com/2400/bmw-wheel-lug-bolt-nut-tightening-torque/ (it sez 90 ft-lbs for Z4's) Rich, that's the first thing that came up when I did a google search for "bmw z4m lug bolt torque"
Thanks Garrison! I think 90 sounds good. I remember it was 75 ft lbs on my NSX. Steven, the mannual was the first place I looked. The BMW mannual does provide much tech info! I just don't want my installer to over Torgue the lugs when installing the the wheels. Thanks Rich
FYI follow up: The number I have found on the net are 88 ft lbs to 88.5 ft lbs. A dealer said 88 ft lbs. Thanks
Yep. 88 foot-patooties, plus or minus. I always go plus, setting my Tork-O-Matic lever to 90 (I have an amp that goes to eleven). Of course, I haven't had that wrench calibrated in twenty years...
