I found two schematics for torque specs for the LCA installation. I have a 2014 IS350 and now hope I did not over torque the boltS. Looks like I found the specs for the 2is and later looked up the manual for the 3is and one says 111ft# and the other 150ft#. Do I need to re-torque my bracket.
Neither diagram is correct for your car, but the bolt in question is only over-torqued by 8 ftlbs if you did 151 ftlbs.
The first pics above is a 3IS AWD and the second pic is a 2IS RWD.
Here are the specs for a 3IS RWD:
