R55 Clubman Lug Nut Torque?

Clubman Lug Nut Torque?
I removed my Wheels today to do a good Cleaning and Waxing.
(Oh that darn Brake Dust Varmit keeps sprinkling my wheels)
Now I'm a little worried about the proper Torque.
I used a 4-way and tighted to what seemed to be the same to loosen.
But I haven't calibrated these Guns for awhile.
What should I do?
I don't own a Torque wrench but am willing to get one.
I know that Chrysler has a "Special" lug nut socket that clicks when it is torqued to the right ft/lb. Is there such a device for the Mini?
Anyone know the proper torque for the Clubman (non S)(I think R55)?
Please reply!!

Found this in the Owners Manual:

[FONT=Arial][SIZE=2]
Tightening the lug bolts
[/SIZE][/FONT][FONT=Arial][SIZE=1]Tighten the lug bolts in a diagonal pattern. Immediately have the wheels checked with a calibrated torque wrench to ensure that the lug bolts are firmly seated. Otherwise, incorrectly tightened lug bolts can present a
safety hazard.
Tightening torque: 103.3 lb ft or 140 Nm.

tire rack sells an okay torque wrench that i use only for torquing wheels. so far it's pretty good and has kept it's range after 5years. I also have 3 other torque wrenches of varying range and I use the more expensive (snap-on) one to check the tire rack one and it's usually pretty close. for occasional use the tire rack one is good enough in my book

103 ft/lbs!!!!!!!!!!!!!!! WOW.
I thought the Audi was tight at 85.
But then again, these cars just urge you to drive the wheels off of 'em.
BTW: I just washed my Clubman this weekend. The choice of the 5 spoke wheels paid off. I was able to wash the outside AND the inside of the wheels just by reaching in. Even got in behind the spokes. Beats the hell out of washing the BBS's on my old M3.

if its something as critical as lug torque, saving a few bucks is not a worthwhile savings when you damage hardware, or lose a wheel in traffic.

I would not recommend a HF torque wrench. A few of my students have them.. garbage.. way off torque readings after just a few uses when checked against a Snap-On or Craftsman (ATD) wrench.

Old thread with missing pictures, but HF isn't always garbage.

Yes, a good looking copy is easy to make... Quality of materials is another.
I'll stick to sleeping at night, thanks.
No, not all HF is crap.. But mission critical torque values are not worth skimping on.

Oh and the craftsman torque wrenches are crap. If you're at that price point go to Home Depot and get the Husky brand one as that one is actually decent for the same money.

I'm not sure I would argue the lug bolts are mission critical. Yes they need to be tight but just how tight is debatable. Obviously there is a torque spec and the torque spec for the R56 is something like 104 ft-lbs. I did a stud conversion and now I torque them to 80 ft-lbs because we used the 14mm to 12mm conversion. Does that mean my wheels are now going to rip off? That's a difference of 24ft-lbs between the torque specs. The wheel doesn't care how it's being clamped to the hub and you're talking about a 20% reduction in clamping forces (if the assumption holds that clamping forces are directly related to wheel bolt torque).

And, I hate to tell you this, but that Husky Wrench is the same as the Craftsman. Its made by ATD (Danaher / Matco / Husky / Craftsman.. )
No, your wheels won't fall off. Frankly, I think the 104 tq spec is absurd considering every other 4x100 17mm wheel bolt car I worked on (Mainly VW, older BMW) carried a TS of only 80. I think its more about having even torque to prevent damage and distortion than *****-tight near busting lugs.
But when it comes to trying to use a "measuring tool" to attach wheels to cars.. I'd rather use decent stuff (Personally, I have Snap-On torque wrenches..)..

Well, I guess you have never seen customer's wheels come off (I have), only to see the car on a flatbed towed back to the shop with body damage as they slid into a guardrail... or seen snapped wheel bolts and stripped hubs (I have) or distorted brake rotors and wheel hubs from unequal torque (I have..).
HF claims accuracy to 4% and this and this test seem to support that. Even if it's off by 5% you're talking about a possible torque difference of 10 ft-lbs from one lug to another if torqued to 100 ft-lbs. Seems like hardly enough of a difference to matter but I'm no expert. Seems like the condition of the lug nuts/hubs could cause more of a difference in torque values than an un-calibrated torque wrench.
Don't get me wrong. There is absolutely a time and place for accurate torque wrenches. You wouldn't catch me replacing a valvecover or rebuilding an engine with a HF torque wrench. I've also never personally owned (although I've used) a HF torque wrench. The point I'm trying to make is that a crappy $10 HF torque wrench is perfectly sufficient for somebody who just wants to rotate tires every now and then and do a brake job. Hey it's way better than "gutendtheit" If they're worried you can always check calibration with a weight and a measuring tape. Torque = Force * lever arm distance.
