I have a question on the mounting of specifically the M5 Sway Bars, but also, in general, any sway bar. Last weekend I replaced most of the front end suspension and steering components (LCA's, UCS's, Tie Rods, Center Link, Idler Arm, and the front Sway Bar Links; struts and shocks going in tomorrow). I pre-weighted the car as recommended with about 600lbs (12-55lb bags of cement), but I couldn't get to the actual sway bar replacement last weekend so I plan on tackling both front and rears in the upcoming weekends.
My question is this: since I need to return the bags of cement soon, do I still need to pre-weight the car if I'm swapping out just the bars? It's really a matter of how much longer I keep the bags of cement at this point.
You only have to load the car for tightening the upper/lower control arms and only for the bolts opposite the strut on those. For the rest you don't need to load the car.
I wish I had done that to mine. Now I am looking on a new set of upper/lower control arms
