Hi again,

Well I know that my tires have more than 18000 hard miles and I also know that I need alignment. These reasons as I suppose provide me with a very low traction.

Apart from my tires’ wear and the lack of alignment IS IT ANY chance that there might be a problem with my stock LSD so I may lose in traction? There is no strange sound coming from my LSD, LSD oil is changed and the LSD makes its presence as it concerns drifting etc.

In other words, is it a chance that the LSD is malfunctioning without giving any strange sound at all?


Thanks

Not really, but I guess its the same chance that you have a tumor in your brain and it is slowly causing your body to malfunction, yet it manifests no obvious symptoms.

yeah, 18k is about the usable life for hard driven maximum performance tires, welcome to sports car world

describe your low-traction symptoms....

there likely would have been an unusually large amount of metal sludge and/or metal pieces present on the magnetic drain plug if the LSD was off in that amount of mileage

most street tires are designed with a harder compound as you near the wear bars to slow down the wear and preserve what small amount of tread is left, plus the usual heat cycle hardening to boot. Most likely your tires. Get a new set and alignment, which you'll need regardless, and you'll have your answer.

make sure the rear tires are not overly inflated too ...

ok this is fair. However, in case that your LSD was off SHOULD you hear any noise signaling that your LSD is off?

Is it possible that a torsen will stop to work as an LSD without any noise at all? I mean that a torsen either works or not. There is not medium stage. So in case that torsen fails it cannot be done without any noise.

update

New tires but in slippery roads the car seems to have no traction at all. How come? Is it the torsen that in low speeds and slippery surface binds and unbinds having as a result no traction?

It is very strange because there are roads with very hard and close turns that the car literally sticks and on the other end I experience slippery roads that my new tires seems to have no effect at all.

Is it possible that my torsen has some malfunction ? I can hear no strange sound but having new tires and no traction at specific circumstances (slippery road and low speed ) it is quite strange. A clutch 1.5 way shall make any difference ?

Your not giving enough information as the cars conditions at time of lose of what you feel is traction. i will tell you my can if your on wet pave me and have the steering wound tightly the car will be more prone to wanna slide lateraly especialy in tight right handers. you may be cresting a hill at hi speed that has a blind turn and the sudden drop can lift a tire of the ground for just an instant. Someone Correct me if i'm wrong but the DSC measure throttle input, brake force, wheel speed, and cars pitch thru the headlamp leveling system( used to monitor cars pitch angle) and adjust the first three afformentioned items accordingly. as you are loosing traction are you getting the TSC light in your dash. also i know an idiot up the way from me that holds the dsc button in just to disable the system entirely just to drive the car like a nut.

not saying you are but assuming the car is in working order remember to a certain extent it is smarter than the driver. at hi speed it will most likely understeer than oversteer cause thats what it was programmed to do. its proven fact the most drivers dont have good hi speed skills so almost all automakers make their cars plow the front end rather than fishtail to death becuase the government says its safer.

What kind of tires?

What do you mean by "no traction at all", or "my new tires seem to have no effect at all"? These are ridiculous statements.

I suspect you have bought ultra-performance "summer tires". These don't necessarily handle great in the rain, especially if it is cold. Also keep in mind that brand-new tires need some break-in before they reach maximum grip.

Well my new tires are 050 A with W velocity indicator.

It is not easy to describe your feeling of no traction. I will try to give you a better description.

No problem in wet terrain actually 050 A are handling better at wet terrain than 040. However, at dry terrain and specifically in slippery roads with a lot of dust and at low speed hard corners I feel the rear end very lose having bad traction. My car starts drifting and the DSC light comes on and finally after DSC break application the car stops losing traction.

I have tried even with DSC off in the same road and my car just drifts like having 300+ whp. My alignment is considered to be stock with -0.50 front negative camber and -1.00 rear negative camber.

On the other hand in better quality terrain the car handles perfectly no problem at all even in very hard and tight turns.

I believe that in slippery dry terrain with a lot of dust and at low speed hard turn my LSD is binding and unbinding causing lose of traction and drifting when you actually want to follow lines. I know that is difficult to have a torsen with problems and not hearing any strange sound.

My tires have 1500 miles.

i myself experience the same situation i believe uts only when the wheel is cut tight though for me wich is normal if your steering wheel is near lock position. basically ur lsd is cause ur lose of traction by itself. may need to have it checked. its alot to type but i could give u some basic ways to check this out withought gutting ur diff. pm me and ill give u number so u can call me
