Many of the used c63's I'm looking at don't have LSD. What are the major advantages? I live in So Cal, and probably won't be driving in rain/bad weather. I also plan on modifying the c63 (tune, headers, exhaust etc) so It won't be stock power. Should I make it a point to have LSD? Or is it not that big of a deal?

Thanks!

Have you ever made a turn and wanted to put the power down, but all you're doing is spinning the inside tire? Power is put down more efficiently. IMHO, a LSD should be one of the first things you do before any power upgrades. Plus, you won't look silly doing a 1 wheel burn out. lol

If you dont have an LSD, you dont have a sports car. and lol at 1 wheel burn outs

James@ACG

Just bring it down to us after you pick up your c63 and let us put an LSD in for you.

What does it cost? and how long does it usually take?

What else do you guys do? Tunes?

I live in Huntington Beach, but I'm in SD at least once a month on the weekends.

James@ACG

We do Oil changes to superchargers on the C63. We have the flashing station here so that you can have your vehicle tuned same day.

the quaife unit is $1750 out the door, price includes sales tax, install kit and labor.

+1, get the car you like and if it doesn't have the LSD, take it to James -- a highly recommended and very professional vendor.

FWIW, my '08 without a LSD lays two strips of rubber. (So did my '02 Civic with FWD and 120hp, with a good clutch dump)
I think the one wheel peel notion comes from the 60's muscle cars without a POSI rear end...

stangxs

Good to know. Hopefully picking one up soon. If I do end up getting one without LSD, I'll definitely take it down there for that + an ECU tune. Thanks.

you dont need an lsd. a road course is the only place its gonna make a difference and only if your last name is schumacher.

I'm doing fine without the LSD since two years and I drive the car pretty hard.
Gotta admit though, I don't track it very often and it has no serious go-fast mods.

Hans Delbruck

This is true.

And having tracked 2 different S2000's, one without a LSD and one with an aftermarket LSD, IMO it is trickier to drive the LSD equipped car out of the corners. Yes you can use that power to to get through and out of the corner faster but you have to know how to

JM

but can you do perfect burnouts like me ?

propain

At the track after the tires warm up a bit I was having some issues with not getting a proper burnout. But honestly I think it only messed up 1 run where I spun so much I stopped the run.

LSD is not a MUST. It's just an extra addition like all other options. Depends what you want out of the car. Either way, it's cool.

I am Jeff

It's a must if you drive in the city and like to power out of those turns without losing momentum because 1 wheel is spinning too much and traction kills the power. That's just from my experience.

olszowa12

No but I can drift the car perfectly even without the LSD
Burnouts away from a dragstrip are no fun.

ZephyrAMG

I can see what you are saying...but seriously, trying to drive all hot and heavy in city streets, especially where I currently live where there are cops are hiding in every tree like a monkey, it's near impossible and frustrating to get some exciting driving in. I almost LONG for a small stretch, a non-trafficked road, a stone-less curve that I could let her rip. I am waiting to hit the track here soon. It really is best on the track, and even then some of the pros have stated that its a iffy necessity. I can understand if you are doing sharp corners ALL THE TIME and getting a rush out of it, or burnouts and your girl looks at you and mouths the words "your hot big boy", thats cool. But I get the idea that for a majority of people its more a " I have it and you don't" option that really never sees the beef of its meaning.

I don't know, just my thoughts...

SonnyakaPig

You're like a modern poet.

I'll admit I want an LSD. But, I don't track the car on a road course and with DR's I hear I can do fine at the 1/4 mile strip. So, maybe next year, but for now, I'll just have to leave it to chance whether one or two wheels spin on a given street launch.

stangxs

You ran an 11.5 with just a tune and filter?? Damn, impressive!

So a car with or without LSD can practically launch the same, is my main concern? (on a dry street)

CELLryuu

Really.....I cant believe what im reading. I sold a G35 with a non lsd rear end and I do not agree with lsd not being a must. My mustang gt was a blast with the lsd....dont recommend that car though (creeks and rattles drove me nuts)

anyway, i swore i would never get a non lsd rear end after selling the G35. the C63 with the lsd feals more planted comparably, and it has 150 more lb/ft of torque.

I know that the G35 and the C63 are apples and oranges, but I'd much rather have the lsd than not.

ZephyrAMG

Did you buy your C63 with LSD?

CELLryuu

no, i didnt even think about it when i bought it, but i sure do now.

Don't know much about LSD, but when I went from a G35 6MT coupe with LSD to a M45 sedan, I noticed that the M45 felt a lot less planted on rough city streets during acceleration from a deadstop. Not sure if that was a result of a lack of LSD, but I cannot think of any other reason as the rears tires were exactly the same size and width, and the G35 coupe couldn't have been heavier than the big M45 sedan.

Question for the experts: Does an LSD help in the scenario I mentioned above (launches on relatively uneven city roads)? If it does, I would consider it a must have as I hate loss of traction when I am launching the car on anything but the smoothest of the roads. It is hard enough to launch the C63 as it is!

I am Jeff

Your assumption is that I floor the car at every corner, but I've spun the inside rear from even moderate throttle inputs. My traction control was blinking like a christmas tree and cutting off power to control wheel spin. With the LSD installed, the car is now more driveable as it allows mild wheel spin and transfer of power to the outside wheel without much traction control interference. I guess I should be happy that I don't live in shytown, because the cops haven't bothered me so far. I don't live in an area with too many long straights, but when there is, I'm sure to open up the throttle. With that being said, the car should have came with an LSD as a standard feature to begin. I had it on my Comptech Supercharged S2k, I'm glad I have it on my C63.

propain

Thanks.

Yes, no LSD. I didn't have any problems at all. Dodger (Mike) has the fastest non NOS with a 10.7 and he doesn't have an LSD.

I didn't test out any street tire launches however.
