looking at a really nice 2012 edition 1 that doesnt have it. i read it is a must have for this type of car. thoughts? Can i add aftermarket? or only really useful if i take this thing to the track?

thx

Mine came without
Had a wavetrac installed
Improved the car imensely
The climate you live in has a bit to do with benefit

I would definitely say yes its a must-have on the C63.

Exhibit13

My p31 has an lsd and I have never driven a c63 without an lsd, so while I cannot answer your question directly I can tell you this. When I was shopping for a c63 I was told it was the one option I had to buy to make the car more enjoyable and drivable. I was actually told by one former owner to buy a base with lsd over a p31 without, luckily I got one with both though in the end. It was a rare and expensive option but apparently it is worth it so I guess the answer is find one with it.

Go for a higher lock % LSD then the optional factory one.

g-f

Yep worth it.

After two snowy days, I have no real trouble going through snow (I have Hakka8 studded).

In warm weather it hooks a bit better. But the best is to be able to control drift better (if you like those things).

Coming from a S5? Get a LSD. After market wavetrack is about 1000$ and cost me around 500$ to have it installed.

GRP

Must have = YES.

Do not stress about finding a factory LSD. Buy the car you like and install a WaveTrac.

geez $500 install? every place i called around was quoting me around $1500

I have a non lsd car, ans with the mods so far, it has not yet done a one wheel peel outa the hole at the eighth mile strip we go to. The traction is surprisingly pretty good. The way I see it is, if it ever becomes a problem, I'll put one in it.

odonnks

No, Not a game changer. Find the one you like and if you plan to drive in snow or track the car it's just a matter of having a LSD unit installed.

It really comes down to your situation.
Do you live in a climate that gets snow? If so do you plan to drive a C63 in the snow.
Are you going to track run the car?

If your in a warm climate and have no plans to track the car but want a very nice daily or weekend driver adding LSD will not offer much improvement.

In a straight line or a surface with good coef friction it usually is not an issue
With a diff wheel speed or slick surface it is

Yeah local mechanic that's been doing work on my track cars for years. Paid cash.

1500$ is a rip off. It's a 6-8h job max. Even at 100$/h it's still a 800$ job top.

Small performance shops are often used to changing diffs and are usually quite good. In my area there are at least 3 or 4 performance shops I'd trust with my car.

MB will charge a lot and your car might be the first time they do it.

Unsolicited plug
If you planning on retrofitting one and are near OH or can ship the pumpkin I heartily endorse

Way i see it anything that can help traction is good, mines got stock lsd and ive gotten the wheels to slip taking a hard fast turn

My truck has lsd and has been big in the rain particuarly on an uneven road

JeffDL

my 09 didn't have one now my second a 13 does it's a pretty big difference I wouldn't want one with out limited slip.

zcct04

Jeff - can you elaborate? What sort of differences do you see? I'm in a snow-free environment and don't have LSD but once I upgraded to PSS tires, I'm really not seeing much slip at all.

JeffDL

it bites much much harder coming through the turns. even on the straights you can really feel both tires clawing for traction. really should be a standard item on all rwd AMGs.

Girard@ACGautomotive

By far the best mod you can do for this car.

I am Jeff

James hooked me up with my Quaife LSD the moment my car crossed the 1k mile threshold.

JeffDL

my 13 actually feels like it will handle quite well, inspires confidence. I don't remember that feeling in my 09.

I have a 2013 c63 with the performance package (481hp, red brakes, carbon fibre trim)...does it have LSD?

Exhibit13

It was an additional option on my 2010 p31

Cee6three

So how do I know whether or not mine has LSD?

Exhibit13

You can look under the car or you can look at the build sheet.

Cee6three

under the hood where it has all the 3 digit numbers?...which number am I looking for?
