Rizbel, did you get your caliper stickers from Nick on as well? If so, need pics.

You are kidding about the jumping part, right? The manual states 88.5 lbs for my car.... yours may be different. Refer to the manual for lug bolt torque specs and get your self a good torque wrench for $50. Then you better redo ALL of your bolts. Especially when you runs spacers, you'd better torque them right. It's a safety issue!!
What is the torque at the bolt when a 175 pound person jumps 14 inches into the air and then lands on a lever, the length of which is approximately 28 inches from the bolt?
I don't know the answer, but I know it is more than 88.5 ft-lbs.

During the switch from 18" 124s to 19" M166s, I broke the bolt (wheel lock) leaving 1/3 of an inch material
in the hole. Just ruined my day
. I tried to EZ out but the drilling went off center
My only consolation is that I can still drive with just 4 good bolts on the right rear wheel. I have to take it to a good shop tomorrow. The pain....

This sounds like an exam question in college for physics majors:

Even if he just stood on it, rather than jumped on it, that would come to 408 lbft.

my god, you can easily over tighten them just by turning the wrench by hand if your not careful, let alone JUMPING on it
, dude, DO get a torque wrench, and have somebody who knows show you how to use it, as it can also be damaged if you don't know what you are doing. Meanwhile I'll say a prayer for you.
