cuz i will be tracking my car and the oem 1 way lsd isn't that great...it always locks up due to why s2000 tend to spin out easy...with the aftermarket lsd u will have better traction on acceleration and deacceleration around turns

1 way lsd= only works when accelerating
1.5 way lsd= works while accelerating and some effect on deaccelerating
2 way lsd=works at all times

they don't spin out easily, it just means you don't know how to control the car properly.. i haven't spun it out and i drive like a maniac... and i've gone on several drives with other s2kers through the mountains at relatively high speeds going through the twisties with no problems...

 

but as for you question... i say you take the car as it is to the track first and run it... that'll give you a better idea of what you need and what you don't need to achieve your goal....

There might be some truth to your reason. The helical type found in the stock unit function more like an off and on switch. If so, the transition can only be abrupt as it switches from open to locked diff. I can see how this can upset the balance of the car. I know a clutch-pack type can be tuned with a certain amount of slippage before locking hence the term clutch.

someone correct me if I'm wrong.

 

 

yes i know i have only driven my s2000 for about 6 months now...and its my first FR car..also i am more use to driving ff cuz i have driven ff almost all my life...so i gots alot to learn with my s2..i've been driving for 11 yrs and have raced ff cars many times in my life time...i also drive my s2 pretty hard..almost spun out twice and barely recovering...goin into turns maybe too fast or accelerating too fast out of the turn..but i want to take my s2 to the limit so i can know what this car is capable of doin, u need to push your car to the limit in order to knowing your car right?...also i am doin my race clutch/flywheel setup and i also have the money to do the aftermarket lsd and final gear setup..so i might as well do it all at once and save me the labor...i would like to learn more about my car with the better lsd than having to learn it again

this is also my first fr, only had it for 10 months, and i've been fine... i agree with you on the saving money on the labor... ... now as for which lsd might be better... i would go talk to vapor about it... or go to http://www.s2ki.com there's more people on there that will be able to help you out on which lsd to get....

No matter what I suggest, you'll end up plopping down the dough for a 2 way LSD anyways. But, that said, I'll speak my thoughts.

The quote above is a poor attitude no matter what you are taking out to the track. There are hundreds. Actually thousands of S2000 drivers who take their car to the track worldwide. I have yet to see any complaints on an amateur level nor a professional level on the stock LSD. Maybe upping it ot a 1.5 way, but that would be it and can be a bit extreme for some situations. If you don't know how to drive the car stock, as is, you will have a lot more learning to do with a 1.5 or 2 way LSD. Having that LSD back there will not improve your driving. It will not make you any safer out on the road nor the road course.

Spin outs? Yea, I've done them, on the street doing stupid things and on the track as well. It happens. But the almosts, too often, in an uncontrolled environment is typically the problem. Once you take it to the track, there are more things to work on and worry about than spin outs. As long as you understand the car's dynamics, you'll understand how to drive a RF. That doesn't mean your FF experience doesn't equate to anything, but there is a difference. Stick me in an FF and it would take me a great deal of time to learn how to drive that thing. But one thing is for sure, I wouldn't stick a different LSD in it, or do anything to it at all, before I went out to the track and actually learned how to drive it, instead of going off of theoretical (and incorrect) assumptions about the behaviour of the car.

Yes, I said 'incorrect', so before you defend your case, I'll state this: most of the individuals going from a FF to FR chassis, especially this one, do not adjust quickly to a 50/50 balance, as well as the quick weight transfers.

It's your dough, your time vs. everyone else's experience and advice. Best of luck in whatever you do.

 

i understand your point...and its a good advice to take...but i already purchased the aftermarket lsd and other drivetrain mods...so there no turning back...i will just have to learn the car the harder way...i am ok experienced with the oem lsd anyways...wish me luck and i hope i am happy with it...thx all

 

which lsd did you end up going with?? and make sure to post feedbacks on it..

 

went with the spoon 1.5way lsd with race clutch combo/flywheel and j's 4.44 final gear...will definitely let u guys know how it does

 

Raymund, you're actually wrong. Clutch pack LSD's are known for being like an on-off torque converter depending on what the clutch packs are made of. Torsen type LSD's like what Quaife runs and other OEM applications needs Torque to work and on a car that lacks torque, it often operates like an open differential. You'll know what I mean if you get one wheel stuck in the mud, or snow, or water while the other wheel has traction. The wheel that has no grip will continue to spin. Ironic for a car that has a LSD.

take this guys advice, it applies to all aspects of mod'ing your car for performance reasons.

Save your money on the labor, you wont be saving much since the work needed to do on the diff is seperate from the tranny work. You don't need a race clutch or flywheel to drive this car at the limit. You don't need a clutch pack LSD and lower final drive to go to the limit. What you need to invest in is a second set of wheels with tires and get brake pads and seat time at the track. Only then can you lower your lap times and improve your driving skills. I'm surprised to hearing about what you want to do with this car if you've raced in the past.

no, you don't have to learn the harder way. Don't install the parts till you've done 5 track events at the SAME track. Why are you trying to make things harder for yourself? It's your car and you can do whatever you want but if you ask for advice and end up not taking it, what's the point of asking?

This car is already a handful to drive at the limit, adding mods to it will only make it harder to drive. Mod at your own risk.

 

i love lsd

It sure is. One time at the track made me realize i modded my car too quickly...and the only thing i've done to my car was change the suspension.
