LSD Help
I've searched and read the LSD threads, but I have a few questions and would appreciate some feedback.
1. Does anyone make a Torsen type LSD for the GS4?
2. Has anyone had any maintenance problems with their clutch type LSD?
3. Does the LSD help the GS4 get around in the snow?
4. Is there any negative interaction between the VSC and the LSD?

Anyway:
1. Yes, Toyota made / makes one for the Supra with 3.76 gears; you can reach Steve G. @ Carson or RMM or Suprastore.com; I think ball park they are ~$1100 retail
2. No experience, but I don't think so, though teh clutches can wear out over time, more so than the Torsen type, though with the cluctch unit, probably not a measurable / significant amount
3. Theoretically, yes, the the GS isn't a snow car; tires have a lot to do with it as well
4. Define negative j/k The VSC will interact much less often since the the LSD will split / proportion the torque between the wheels, lessening the propensity of the wheels to break traction.
FWIW, I don't have one installed yet, but I have done a lot of research on the LSD units, and am in the process of acquiring one with an install scheduled later this month. I went with the 3.76 Torsen unit, for just a few special reasons.
I'm sure a couple of guys who have had thiers installed and used for a while will chime in and add their experiences as well.

The negative interaction I was thinking about is when a wheel slips you have the VSC trying to stop the slipping wheel by applying the brake and the LSD clutch is engaging trying to turn the slipping wheel. Depending on which device is faster I thought they might fight each other.
Do you know if the Torsen type is available in the standard 3.23 ratio?

Actually the LSD will compliment the VSC. It should premptively prevent some of the slipping the VSC will want to prevent.
The LSD (mechanical) is the first line of defense, then the VSC (electronic), so therefore, as I mentioned previously, the VSC will come on less often.
Right, what Jacob stated, but that also may be cost prohibitive. After dropping ~$1100+ on the LSD unit, then paying someone labor to swap out and set the ring gear. Setting a rear gear is pretty tricky stuff from what I've read and been told.
Looka t it this way, if you anticipate getting larger wheels and tires, the 3.76 LSD will help you push them; that's one of teh pluses I considered in my decision.
Although, if you are asking about snow, I doubt larger wheels and tires will help your effort. :eek:

Let me add my $0.02,
1) What they said (Toyota/RMM is a Torsen)
2) Nope. I've had it for a couple thousand miles now and I'm using Royal Purple 85W140 oil with no problems
3) Absolutely! The tires do matter (I've got 16" snows on mine now) but the biggest gain from the LSD. It drives around very comfortably on snow tires and LSD. I would go so far as to contradict Dexter :eek: and say that it is a great snow car now!
4) Nope. As has been said the mechanical action is quick enough to not cause problems with the VSC and everything works just so much better.
HTH,
Peter

Oh sure, with the LSD, you can romp around in the white stuff, but still.....

I like the Torsen type for low maintenance/longevity (100K+ mi.) purposes, but want to keep the stock ratio. The TRD LSD is listed for $800 and the RMM LSD, on supra.com, is listed at $1,500. Unless the RMM is heavily discounted, it would be hard for me justified the additional cost based on maintenance. It's good to hear the LSD greatly improves the go in the snow and as an added bonus I'll be able to accelerate harder out of the corners.
