I always felt like the slop was mostly the rear sub-frame - you could really notice it if you pulled the e-brake on while it was still rolling a little that it would REALLY rock back and forth - and that would only be suspension related.

So, I installed the solid bushings. The install really wasn't too challenging with the use of a lift. I used the heat and jack method, and the whole job took only about two hours. I also swapped on an LPW differential cover - for those of you wondering - YES, you can do it without pulling an axle and dropping the diff out.

Man - wow, what a difference. I felt it from the first release of the clutch backing out of the shop - just everything was solidly connected. Much less potential for bucking, much better shifting feel, pedaling through wheel-spin is nice and smooth, no wind-up on launch, this should be a MUST DO mod for even a stock M6 car. Autos will benefit too, but the M6 especially moves that cradle around a lot! If you're on a tire and you've got aggressive gears, it's the only way to be. It's worth every penny.

Note - I did not pick up any type of road noise at all. No clunks, bangs, etc. I did pick up a good bit of gear whine. My car has 4.10s, and they were not quiet to begin with (has had BMR pro bushings in the diff for a year). I added the LPW cover at the same time as the solid bushings - that has load bolts that go right down to the main caps on the ring gear. And that cover has a BMR pro bushing in it, and then solid cradle mounts, so the noise has a pretty straight shot to get up to the body. I think the LPW cover has a lot to do with it. No complaints though - I'm doing race-car stuff and that's a side-effect I'm willing to live with. I bet most sets of gears aren't this noisy either - most guys say they have no noise.

wanted to ask you. What torque specs did you install the pegasus mounts at? Did you buy new bolts or reuse the stock bolts. thanks
