I would say the kit would have the two bearings, two seals, and a couple of liters of gear lube. The biggest part of this job is getting the diff out of the car and onto the bench. The only things that are critical is to make sure the correct bearing is put on the correct side, the snap rings don't block the oil holes, put the new seals in square and to the right depth, and to put in the correct amount of lube.

I emailed ACG and pm'd Peter@ACG but didn't get any responses. Are these guys still in business?

I can't get a decent response from Quaife direct. Still trying to get confirmation on a later / updated version.

I am thinking about pulling the trigger on the LSD before my next track day. Did anyone get one installed yet?

Another post reports that there was never an updated version - just out of stock and a misunderstanding that that meant a newer version was being released.

My car is in storage until March - I'll buy then and install.

i was the one that started the "updated version" rumor. when i left the deposit for my LSD, i got a call a few hours later saying that quaife was out of stock everywhere and they were making a new version for the c55. although, this piece of info. wasn't directly from quaife. it was from their distributor.

Want to install 2 at the same time?

DONE - I'm in.

has anyone done a Quaife install for their car in the bay area? love to find out where you got it done at.

i would've had it done at ASP in daly city. he was very reasonable on the price, but call him and find out if he can get one. talk to vlad and tell him michael with the c55 sent you
