Wheel nut torque

[rstoughy]

Had a browse using the search function but never really come up with much.

Whats the general torque setting for the standard wheel nuts?

Do any of you do them up differently for track?

Cheers,

i use 120Nm for road and track. Tighten on track after your first outing and maybe check again at lunchtime BUT i have never had a nut come loose EXCEPT just after wheel refurbs when if they painted on any touching surfaces the nuts will slacken off

Cheers guys, just done my reps for track and have made a point of running a die grinder with wire brush through the bolt holes to get excess paint off :smokin:

I torque a little higher than Specified for track work
The car is put through loads never seen on road, ESP with sticky rubber

I go 130 for track, and check often throughout day, shimmy and Glendogs way is fine though

The key is to monitor throughout the day to avoid incident, just as they advise too

BMW was documenting 100NM up to 2 years ago.
Since 2 years ago, all BMWs need to be tightened at 115NM.
For wheels with diameter greater than 17", you need to drive the car 10km or more and then check again.

Over tightening the nuts is a very bad idea for 2 reasons :
1. It might bend the hub of the wheel
2. When the brakes + wheels overheat, the nuts can break
I have seen both ^ in customer's BMWs.

I think you would have to seriously overtighten to cause any of those issues Alex, and our BMW;s use bolts.

So if BMW got it wring for all these years a good reason not to do what they recommend :whistle:

I've always gone with the power bar and the "that should be tight enough" feel from my mechanic days but at the last track day i was at there was the distinctive sound of a wheel bolt snapping followed by one very pi$$ed off Escort Cosworth owner.

Got some bright wheels for the 2011 track season so i dont want to loose any of them :hahaha:

Ford and rust are like 2 peas in a pod though:hahaha:

To be fair, you must be a twat to snap a wheel bolt when tightening it up. Most common snapped bolts we see are cheap nasty locking bolts that people buy

Most of the lads on here inc myself, never give the wheel bolts time to seize, they are on/off more times than a whores draws. :thumbs:
