[QUOTE=cbl117;17859370]I thought that history was due to not replacing the sub frame bolts since they are recommended as one time use (per BMW tech). Anecdotal data says the bolts, if reused, loosen over time and required re-torque. I replaced my bolts with the install and haven't noticed a change in the feeling of the car over the 6 months I've had them installed. But I guess time will tell.

The bolts do NOT have to be replaced and they are not one time use. They are 10.9 cert steel and can be reused. I had the M3 bushings installed at the dealer here in Schwandorf (Germany) and they reused my original bolts. I asked about the one time use thing, and they told me that is a myth. Nothing in the instructions says to replace the bolts.
