M3 Control Arm Torques settings

Recommended Posts

Could anybody clarify the torque numbers for the suspension arms etc? 
I have found so many different specs on old forums and YouTube videos with varying numbers of “correct” torque.

Did this couple weeks back, great mod!!

Was varying torque figures, just used long spanners and breaker bar with 1/2 inch drive and did things up tight.

Be sure to go straight to alignment and not to far away if you are DIYing.

Yeah I’ve just finished installing coilovers front and back and the M3 arm up front. None of the wheels are now facing forward 🤦‍♂️  
Just called the alignment shop and they’ve already closed. I’ll have to wait till next weekend now. 🤞🏼
