hmm i always thought s2ks have lsd's. its snowy here in chicago and i was getting up my garage because i have an incline. and i got stuck. i got my brother to help me get the car in, and while i was watching the car go in (and getting unstuck from snow), i only noticed one wheel spinning.

 

we do have an LSD. Just because both wheels aren't turning 100% of the time, doesn't mean we don't.

 

but the drivers side wheel was literally not moving.

i think your thinking of a locking diffrenta also known as Positraction diffrental (LSD) not the traditional LSD the s2000/most sports cars has. but i could be wrong

 

The differential is a torsen unit. It requires a little resistance to function. Next time apply the parking brake slightly and it will lock up.

The torsen works on torque multiplication ratio determined by the worm gear. If one wheel is off the ground or is in some situation where it has COMPLETELY or almost COMPLETELY lost traction, then 0 multiplied by anything is still 0....which is the amount of torque that will go to the other wheel.

All S2000s came with a LSD. The LSD never "wears out" per say. It works via a worm gear.

 

 

well is one wheel supposed to spin only? like when i chirp tires and/or i lose control from shifting and releasing the clutch too quick, my whole rear end starts sliding to the right (for a little bit).

 

lsd= limited slip. not full time locker

The reason the car squirms when you shift is because both wheels are spinning. The rear end is "floating" at that point, so it may go left may go right depending on a lot of stuff.

If both wheels have atleast some traction, they will both try to spin if enough torque is applied to them (only in acceleration).

The only conditions where the stock diff is open:

- If one or more wheels is off the ground or there is WAY too much of a difference in traction between the two wheels (i.e. putting one wheel on ice and the other on dry concrete).

- Deceleration

Go to howstuffworks.com and look up "torsen LSD" or "helical LSD".

 

but my car moves to the right when i gas it too much and the wheels spin excessively.

it feels as if only one wheel is spinning(hence why its moving to the right only?)

i thought an lsd is suppose to even the torque out between two wheels so one wheel will not get more spin than the other?

You're not understanding. The LSD does even out torque.

The car will not slide to one side if only one wheel is spinning as the other wheel will still have traction. If only one wheel spins, the other one holds the car in place. It may kinda wander to one side...but that's different.

If what you're talking about is happening under normal accelration as well, try getting an alignment and checking tire pressures. If the tire pressures in the back are off from side to side by more than 1 or 2 pounds, the car will pull like crazy on acceleration. That doesn't mean the wheels are spinning...it's a common issue.

The tire pressures all around are 32PSI (COLD) as per honda. Check that...see if the pull goes away. I have seen this in person. Also, check your alignment as the car is very sensitive to alignment changes.

 

this is not under normal acceleration. this is when im overspinning the wheels. (when im giving more gas than i should, and the wheels are losing traction). the lost of traction is causing my rear end to slide to the right.

 

oem lsd = pos

 

maybe u need a tire alignment?

If the WHEELS (plural) are losing traction, the car will slide around. If ONE WHEEL (singular) is losing traction, you will not slide around.

The fact that the rear end is SLIDING out, validates that the LSD is working. BOTH wheels have to spin for the rear end to slide. When BOTH wheels spin, the rear end is essentially "floating". The road's slope or other factors will make the car slide to one side.

This scenario is true when the car is SLIDING from side to side. NOT ducking and pulling.


Check your tire pressure. Make sure it's even from side to side (32 PSI cold). This is a HUGE factor in pulling or weird behavior from the back end.

Check your alignment. S2000s are VERY VERY sensitive to alignment changes. They toe OUT under compression. If one side is even slightly more toed in/out than the other, when the rear suspension compresses, the car will duck and pull when you DONT spin the wheels, and if the wheels spin, it will definately want to slide to one side or the other.

ROFL ok Mr. performance man....remind me never to go near your shop.

seriously, how hard is this concept to understand. there is nothing wrong with your LSD dude, now go to your nearest tire shop, get some air and a freaking alignment. mace sure they give you a spec sheet print out, and if your still having problems, come back and talk to us.

lmao

 

Wow haven't been here in a while. To amke this easy the s2k has an LSD. I think in '06 it had traction control.
