I�m baffled as why a racing car company like Porsche didn�t put lsd as standard in a sports car of the 911 caliber
I think it�s a shame the didn�t lateral grip in a rear engine car would have made turn exit speed that much safer and faster
just would like to know why
Cost and comfort. I can tell u with the gt3 trans (has a ls) i feel it all the time. It was always an option but most did not click the box. Also i have tracked the car with and without and the c2 version did just fine, but the ls is needed with the extra gt3 power
Comes in handy in the snow for grip and certainly on the track for stability, balance and traction. Most don't miss it unless they are seriously tracking it.
What Rat70fi said. All 40th anniversary car got the LSD from factory and I've seen quite a few early build cars with it. A while back there was also a standard Carrera for sale on BaT with the X51 engine from factory and it also had an LSD so perhaps there might be a correlation there. 40th cars and any spec'd with the X51 option were as close as you could get to a GT3 power wise without actually having the GT3, and obviously the superior Metzger engine. I'm not an LSD expert but the factory LSD had locking rates of 22% under acceleration and 27% under lock-up.
The Turbo, C4 and C4S drivetrain acts like an LSD. If a rear wheel starts to slip, then power is immediately transferred to the front wheels which causes that rear wheel to stop the slipping. So, with these build numbers:
- C4: 32,670
- C4S: 23,055
- AE: 1,963
- Turbo: 21,954
- GT3: 5,898
- Gt2: 1,287
Total: 86,823.
So 86,823 out of 175,164 total built, means at least about 50% had "limited slippage".
It should have been standard.
My early 99 has a LSD that was part of the 014
Sports options package.
(LSD, M030 suspension and Sports seats)
Definitely worth the extra $2,885
The 996 C2 is a street car, not a track or race car unless heavily modified with oil starvation etc. problems solved, lsd is minor cost at that point. I have an lsd in my BMW, rarely utilized in the street and will probably never track it.
Turk I don’t think you drive your car hard enough I use it in my E30 M3 constantly
the first time I went a little wild in my 99 911 I almost lost it on a slightly damp road the pendulum effect is prominent
in roundabouts with a 911 You can carry some speed in my 911 it scared me straight forshizzle
Nothing minor about the cost of adding an LSD. $2-3K for the hardware (I would only go with OS Giken, Guard or Porsche Motorsport) and upwards of $1K to install and machine stub axles / case is a lot of money for me at least.
The cars are way better than one would think they should be without an LSD in my opinion - Ton of rear grip probably has a lot to do with that.
However, a good LSD allows a much greater level of exploitation of that rear grip. It was a huge upgrade for me.
Quad, you are 100% right.
But if you plan on tracking your car more consistently and strive to get faster, it's a necessity.
It's kinda like trying to get extra HP in your car, but only drive it around the street. Or get a big brake kit, suspension, or whatever....you get the idea.
It's a nice to have, but you really can't use it to its fullest on the street. So it may or may not be money well spent.
But on the track is different. You are looking for every edge in speed within the regulations you drive in.
I have mixed feelings about LSDs if you're not racing. Having owned a Z with a Nismo 1.5... slow speed maneuvers and parking in parking lots made me wish I never installed it.
Yeah, there is a plus and minus to any upgrade and to Quad's point, in most cases you don't need it. LSD, big brake kit, mega suspension upgrade, racing seats, etc.
Is it really worth an extra 15-20k if you don't really need these things?
Sure I did it, but over a series of years and keeping my eyes open for bargains. No need to pay 6k for a LSD if you can get a rebuilt one for 3k. Same for big brake kit, racing seats, etc. No timeline on upgrades.
You answered your own question - the 996 did not need a standard LSD to still exhibit better driving dynamics over many of the competitor offerings WITH LSD's equipped as standard.
Having all the weight in the *** means better traction on corner exit. 285 tires, heavy rear, and not a ton or power generally limit wheel spin. Something like a camaro needs an lsd
Yeah but off camber tight left/right power push needs an lsd with all the weight rear biased and 295 rears good tires I still swung the wrong way into a slide because the grip was only on one wheel without power
my initial thread was to find out why a performance car with a history of evil on throttle push swings would you not add a posi diff as standard
thanks to all the responses
Yeah, when you load up one side in a turn, you will have inside wheel spin and that lack of grip throws off balance, speed and the ability to control the car. LSD also helps to stabilize the car during braking. Most people aren't fast enough on the track to ever notice the difference. But if you get serious about getting faster, you gotta have an LSD.
Yeah I know my E30 M3 was my track rat it has a 4.27 posi diff an upgrade from the 4.10 it came with it’s perfect BUT after having a glass out body repaint the car was too pretty and pricey to beat on from my original purchase price of $3k from eBay lol 23 years ago
so I guess I’m driving the 911 too fast on the street I’d better get to a track before I crash LOL
Not sure about that. I pretty much suck and sure can feel the lsd in the new set up but that might be from the added power. Not sure i needed it with the 3.4l.
I think porsche wanted/needed/had to sell cars. No lsd lowered the price point. Many didnt think the 996 was a performance car and thats why the masses pushed porsche for the gt3.
Now that I think about it, the only 350 that came with a LSD was the Nismo model(also came with a stitch welded frame of all things) and I'm trying to think of similar cars from that era that came with a LSD that wasn't an option.
Because if you asked an average buyer if they wanted LSD with their 911 at the time when these cars were being sold new they'd think you're a drug dealer. Short answer is because it saved loads of money at a critical time and for those that actually drove their cars and knew you could add it as an option. It's really as simple as that. Most people think that engineers decide what ends up in cars, when it's really the bean counters.
I installed an upgraded OBX LSD. Bought the LSD and upgraded the bolts and washers with an upgrade kit I found from a supplier that installs them in Japanese cars with great results.
I would definitely not install it without the upgrades. The LSD has worked wonderfully for the past 25k miles on and off track.

Me, too. I also have a mechanical one in the ND and some electronically controlled job in the M3 (a car with no traction at anything more than half throttle).
Absolutely not true or I had the only 2004 Touring 6 Speed Nissan ever made that didn't have one. VDC cars had LSDs and they were an option, Track Z's with the Brembo package may have had it stock but I know for a fact all Nismo 350s came with a Nismo 1.5.
I�m sorry but you�re wrong.
All 350Zs except for the base model came with a LSD.
I just sold my �08 base model 350Z earlier this year.
But I still have the brochure haha.
It clearly shows that ALL trim levels except the base came with a LSD.
Only if you are going to track it or drive it in lousy weather such as snow, rain, muddy and gravely conditions.
If you only drive around town on Sunny days, it doesn't really matter. The Psm will help.
I see now, You had a HR model but the 2003-2005(VQDE) and 2005-2007(VQDE RevUp) models didn't have it as a standard option. You're brochure makes it very clear that the HR models did indeed come with one so I'll retract my statement in saying "all" non Nismo 350z's. My particular Touring had a HKS GT Supercharger and it would peg leg like crazy, once the Nismo 1.5way went in... no more peg legging.
E36 and E46 M3 came with LSD as standard, RX-8 too indeed (I had two of those).
I only learned recently the 996 did not have it, it came as a surprise to me... Luckily my 99 has the option
