LOL, sure it's not 87.245515778488876?
Seriousily, from the TIS...
_______________TYPE_____THREAD____TIGHTENING SPEC___MEASURE____
1AZ wheel bolts__R55/R56__M14/17 A/F___________________140 +/- 10 Nm
A bit high I thought, but that's what it says...

rlnewby, the torque spec is from the BMW TIS (Technical Information System). As ScottRiqui rightly pointed out, the OP has a 2005 MCS and what I previously posted was for R55/R56 as stated on the torque spec. As for R53, the spec as as below.

Some of the first-gen R50/R53/R52 cars used the 14mm bolts as well. The general rule is:
All MINIs built after mid-July 2006 (as well as all of the JCW GP cars) use the newer 14mm bolts and have a torque spec of ~103 ft-lbs.
All other MINIs use the older 12mm bolts and have a torque spec of ~88 ft-lbs.
My wife and I both have 2006 'S' convertibles, but hers was an April build and mine was a September build, so we actually had both sizes of bolts until I installed the 14mm -> 12mm conversion stud kit on mine.
