FWIW, the '87 M6 advertised power similar to yours. It employed the same center driveshaft support/bearing 26111206502. That does not mean it couldn't stand improvement.I remain confident but cautious. I take your point on pre-loading and that was done. The mount is also new. I have 256bhp as opposed to 170bhp standard so 50% additional power means something is necessary. Either engine mounts or propshaft bearing holder, and the propshaft bearing holder was easier.
