2 way lsd is it dangerous for road use and track racing...?

Post by QUOC2008 »

I just want some opinions on 2 way lsd... if i wanted to start racing around a track for a time attack would it be dangerous and would i get slower times than if i had a 1.5 way lsd.

For road use if i felt like going mad racing around on the streets and roads would it be dangerous...

Yup there is other people using the road.. so with or without the LSD it would be dangerous.

If you drive hard enough on the track to fully use a 2 way LSD, you'll need to learn how to drive with it.

Do you actually know what effect it has? :?

Why would you want to race around on the roads-that's acting like a xxxx. :roll:

It's a Torsen LSD. Not plate-type.

I never said that i was gon a race around on streets and this is a question about 2 way lsd compare to 1.5 way lsd...

And why r we talking about s2000... we are talking about lsd

2way is usually used for drifting
1.5 way is usually used for racing circuits n time attack

Its to do with the way that the LSD locks the wheels if it is fast track usage a 1 way or 1.5 way is the way to go

Whether you'd go slower with a 2 way is depending on driving skill. also as the inside wheel doesn't spin slower on turns it makes it much harder to corner properly.

Im not sure if that is true about the inner wheel not slowing down lsd standards for limited slip diff..

2 way just locks up more or completely the wheels in accelaration and deccelaration while 1.5 way is semi full on accel n 50% or so on deccel

#-o

The thing with mods, and particularly handling mods, is they tend not to be dangerous or even necessarily faster or slower. It depends on driver skill and driver preference. A well maintained car is not dangerous... it's the idiot who gets behind the wheel and drives beyond their visibility / skill / car limits that is dangerous.

So you've ansered your own question.

In fact, 2 way has always been used by full on race cars. Long before drifiting was invented.

Neither will make an ounce of difference when driving normally on the road.

On public roads, just drive the car normally.

Here's a really basic video on the subject, which might enlighten you.

On the other hand if you've fitted one already, have at it...

eta.
As for using a 2-way on the road - the big difference will just be the full lock of the diff under heavy deceleration/engine braking. I don't think I've ever heard of anyone suffering from this in road driving though - you'd have to deliberately engage it by being full-throttle, then letting off completely, mid corner. If you did that in an MR2 you'd be seriously unsettling the body anyway, and we all know throttle-off mid-corner in an MR2 is a recipe for disaster. As Pete says, I suspect this effect would never be noticeable on the road without putting yourself off the road in a blaze of destruction.

I can't see why you'd bother with a 2-way LSD personally, but maybe that's because I have next to no experience driving with them.

This is all just as I understand the subject, don't take it as gospel.

Treat the throttle as a variable input, not an on-off switch...:)
