Front end bolt torque specs?

I have searched NAM and haven't had much luck. I'm in the process of installing new LCA bushings, camber plates, and all new koni shocks. I was wondering if anyone had a link or info that would give me the proper torque specs for when I put everything back together. Subframe bolts. Bumper nuts, shock mount bolts...stuff like that.

Thanks?

I don't have my book handy, but with all of the stuff you're trying to do a Bentley manual would be a good investment for you. They sometimes show up in the Marketplace or you can get them directly from Bentley Publishing.

Just a quick note that the spec on the Controll arm bracket to chassis is
44 ft-lb plus 90 deg +/- 15 deg. This is also a stretch bolt with a one time use and should be replaced.

Glad this came up. I didn't have the shop manual when I installed the Alta 22mm rear sway bar. All went well, but I had my torque wrench set to 90 ft/lbs only to discover afterwards that the rates for the rear subframe bolts should hover around the 75 ft/lb mark.

Is overshooting this rate by 15 ft/lb going to ruin anything? On Honda's, it wasn't a big deal on larger bolts, but this is my first go around with MINI's.

Just had to remove my motor mount bracket for a pulley install and when I reinstalled the brakes I tried torquing down the bolt to 74lbs as stated and the bolt seems to be stripped. It keeps threaded and doesn't get tighter. Should it thread this far down?

I'll try and get a photo but I keep getting this parse error notification.
