Strut Bar "Tightness" Question
Hey guys, I recently installed a BMW Strut Bar (The metal one) and I screwed it on the poles very tight. I checked the bar today when I was cleaning the engine and I saw the nuts and screws sinking into the bar and also saw micro bends of the metal. Did I screw the bolts on too tight? If I untighten the bolts a bit would it affect the handling? Thanks guys.

As far as I know the spec is 18 ft lb. Loosen them and re tighten using a torque wrench.

I don't know how else to tell you what I just said in my previous post. It's not about getting them as tight as you can. You need to use proper torque and to do so you need a torque wrench.

18lb feet of torque is not much. Compare to your wheel bolts at 110-120 pound feet.

110-120 for wheels is an outdated spec. There were rotor warpage issues so BMW changed the specs to 80ish lb feet.

FWIW, wheel bolts on the E90 should be 88.5 lb-ft (120 Nm).

okay...120Nm.
To many technical experts around here. My point is 18 pound feet of torque is not that much. OP could have easily over torqued bolts or nuts. An easily correctable mistake...proper settings should be in original documentation. Or, he can call the service and parts department and ask.
