    The same as 348. 72lbs-74lbs. :) I just fitted rear wheel spacers and torqued the spacer bolts to 80lbs and the wheel bolts to 90lbs all round. :):)

    Hey Rodney what size did u settle on? And, yes, use 72-75 lbs.ft. to avoid snapping those little devils. :) I trust you have the correct length bolts for your application?

    I tightened the wheel spacer bolts to 74lbs. I honestly did not think they felt 'tight' enough, as the torque wrench clicked really easily. So I loosened them and re-torqued them to 80lbs. The wheel bolts are a bigger bolt, so I tightend them to 90lbs. I was more comfortable doing that, than tightening them to 74lbs which didnt feel right to me. :)

    No, I have never had it calibrated since I have owned it. I use a torque wrench nearly everyday at work, so I have a good 'feel' for what torque is what and I didnt really think that 74lbs felt tight enough. :) A little more torque on those bolts wouldnt hurt anyways. ;);)

    Heh, until they snap, dude. At least the bolts are soft enough to drill out when you do... :p

    They are 12mm bolts. You gotta be doing well to snap them torquing them up to 80lbs. :):)
