Last weekend I finally got around to opening the big box that had been sitting in my garage for over a year. It had the complete rear subframe that I bought back when I had just gotten the CLK, knowing that the rear end would need some serious upgrading.
It's got a Quaife HD LSD with 3.55 gears in a W211 E55 center section, Driveshaft Shop axles, solid diff mounts, and adjustable toe and camber arms.
Early impressions are mixed. I was told it came with 3.73's, but my TCU says otherwise. Apparently they are 3.55's. The rear end is also noisy AF. I know Richmond gears tend to be noisy, but I'm not sure the gears were setup properly.
I got a few runs at the track, and my best 60' dropped by about a tenth, but I'm still having 3-4 shift issues with my TCU so I don't have a good 1/4 mile time yet, but they definitely haven't gotten any worse.
