Just got a low miles C63 and love it. Already added the OE tune and it's a monster, however, clearly realizing I need an LSD. I'm leaning towards the Quaife, but I need to find a good installer in the general Maryland area. Any recommendations? Anyone work with AtSpeed in Hanover, PA? - thanks DB13715

i'd be interested to know as well. i'm in va, but would be willing to travel a bit since i don't know anyone that installs these.

If you're willing to make the drive up to NYC, I used ACG in Brooklyn to do my Quaife LSD install. They did a phenomenal job with my install and I would highly recommend them.

Got mine installed by a friend at a shop in Tysons.

about how long does the install take? also is there an lsd that's easier to install than another? i think i remember reading here before that one of them requires some extra work because it doesn't fit at first so adjustments have to be made to make it fit.

Funktionauto in Sterling va can do the install

It was just my buddy and it took him two weekends (he was working on something else at the time too). He didn't mention any additional adjustment. I have read something about it though, but I thought it was because there were two similar models of quaife LSD out there.

Funktion Auto did some work on my car, solid team of professionals too.

Appreciate the replies from everyone... SheryarYO - The two that came up multiple times and have stated they have done many Quaife LSD installs on C63's was Funktion auto in Sterling/Dulles, VA and then also TTMotorsports up on Long Island. These were the two that I kept seeing come up and they both had similar pricing as well. This is Funktion's pricing quote:

Quaife LSD for C63 - $1062
Gear Fluid – Motul 300LS - $60
Installation - $1150
All in Cost $2,272

It looks like it's an all day install. I may try and line mine up at Funktion on a day around my upcoming holiday break. Funktion is probably half the distance from me compared to Long Island. After further research, it does seem that the Quaife is a direct bolt on replacement diff for the C63, so I'm not sure there will be many other options that are much easier to install. The Renntech version seems unreasonably priced and I haven't seen anyone post anything saying any other LSD is better than the Quaife. Jeremy from OE Tuning has the Quaife on his C63 and loves it. Good luck.
