Good point; that's why it's important not to overtorque those bolts. I've always done that by hand with zero problems, and probably end up putting a lot less torque than specified. Dealer put mine pretty tight from the 1.2K service, but I assume was done to spec. And remember to always loosen the bolts by hitting the ratchet with your palm; it's a lot easier to strip bolts with steady force than a quick jolt. Works like a charm
