2014-2016 E63 - Open Diff to LSD
First post, so please be gentle. I already did a search, but didn't find any responsive threads. I'm looking to get into a Merc for the first time. I've been monitoring prices of 2014 E63s and E63 Ss (Damn that is weird). There appears to be about a 10k difference in price. I can find a good E63 for low 50s and a good E63 S for right at 61k, sticking around 30k miles.
I plan on putting on a downpipe and tune as soon as I straighten out warranty repairs on the new (used) car, so the "S" doesn't matter much to me, outside the LSD. LSD is a requirement for me, so the choice between an E63 and an E63 S really comes down to the issue of swapping in a LSD into a non-S.
After a fair amount of research, it seems that the cost of swapping an E63 S LSD with an aftermarket LSD is about 2.5-3K installed. BUT, I haven't seen any threads regarding swapping an open diff to a LSD on these cars, any traction control/computer issues that might ensue, and additional costs such as trans-axle issues. Any help is much appreciated.

I haven't bought a S or non-S.... you're assuming I already have a non-s. Trying to get an answer to my question so I can evaluate the choice a little more. So for example: If it's going to cost 5k to install and there may be some traction control issues on a non-S, getting an S with an LSD out of the box makes up for the initial price difference.

Track use (road course) might be the only reason to have to have an LSD and if that's the case an aftermarket product is likely the better choice anyways. But if you've never driven an AMG, their "open" diff might surprise you. It's not a true open diff that only sends power to one wheel. I've never had my E63 non S not put power down to both wheels on the around corners or at the drag strip and I saw ZERO difference on the street or the track in my E55 when I swapped in an aftermarket LSD. However, I was able to swap the diff for under $2k and I'd doubt the E63 would be any different.

I have a tuned non-S model and I can't break traction in the wet much less the dry. To be fair, it's a wagon though.
I'd say try it for a season with snow tires and hit the track and see how it does.
I rocked an e36 m3 in the snow for many years and with the right tires it was solid.
You're not really going to be pulling insane lap times in this thing anyway...I think that the excessive weight and brakes will let you down before the traction does.
I wouldn't place a premium on the S model personally.

Edit: I drove my e46 with blizzaks in the Midwest and it was great. Now with BBK + brake ducts, its a summer/track only car. Just a bit apprehensive going to canyon roads with real snow fall.

1) I ran an e36 M3 with blizzaks and drove to the mountains every weekend with 0 issues
2) I ran my 911 turbo with an open diff and REALLY bad awd and even it was fine in the snow. Note...this had snow tires for sure
3) I have summer tires on my E63 and drove it in 6 inches of snow/slush to the airport in Seattle. It was a bit dicey, but it could make it up small hills etc. With proper tires (read...actual snows) I would be SHOCKED if this car wasn't good enough for you unless you live like on the top of an unpaved road in Gunnison or something.
This summer I might hit a HPDE as well because shoot, why not right? Getting a diff just for that event seemed crazy. My friend has tracked his non-S multiple times and passed a lot of pretty solid cars on the track. He never complained about the lack of LSD (and he tracks his GT4 regularly)

So I'll give you a few data points if it helps (I used to live in Denver)

2) I ran my 911 turbo with an open diff and REALLY bad awd and even it was fine in the snow. Note...this had snow tires for sure

That's super helpful info. I might hit up some HPDEs more than that if/when I sell my M3... but it's going to be hard to part with that car. Definitely not going to be a regular thing- going on a road course. I really had a fear of getting into a non-S, having grip issues, then spending as much for an S just to swap in a LSD and losing out on the re-sale (as it stands now).

Any issues in snow? Going to be running this in Colorado. I have an S4 as a DD and haven't really had issues with an open diff, but it's not in the same class as an E63 power. Really love my M3, which is track only. I've read pretty much every thread on here regarding open vs. lsd and it seems like there aren't very many "happy with my open diff" comments. Could just be that those people aren't voicing an opinion?
