Question for those with proper LSDs installed
 

In turns when accelerating and letting off the gas, do you guys feel that the car is taking a different line?

After installing my KAAZ I feel the car changing lines when I accelerate and let go. Not sure if it is just the soft bushes in all the control arms, or something else is up.

Is your KAAZ a a 2way 1.5way or 1way

Your info is sorta vauge, but it sounds like you're diff is opening up. Have you been changing your diff fluid as you should be, what kind of fluids are you running, how many miles are on it, how much has it been tracked, and drifted?

nah, its not that. iTs a 2 way at 80% lock, and its brand new, 1000 street miles if that.

When in a turn. Give it gas and it wants to go straight? Lift off the gas and it pulls in to the turn?

Yeah, that's what i recall. Ill verify after work again.

Isn't that what you want it to do?

Car is not suppose to change how it tracks in a turn unless you break traction.

A car will absolutely change how it tracks in a turn with throttle, even if you've still got traction.

Your crazy talking :icon18:

Example, look at this
Subaru Impreza S204 vs corvette Z06 vs Nismo R34 GT-R Z-Tune vs Murcielago Tsukuba Battle - YouTube
You can see in some instances that the drivers do gas pedal modulations while keeping the steering input the same and that car is tracking the same.

When I do that it feels as if the car has rear wheel steering. The path that it takes through the turn changes with gas input.

Every car I've ever owned wanted to tuck in when you lift, regardless of diff type or drivetrain layout. Maybe I'm misunderstanding the question?

Weird, cuz every car i've owned never did this. Including a 240sx with the same KAAZ diff.

It feels like rear wheel steering.

I'm convinced that its the soft bushings that are causing geometry changes wile modulating throttle input, but I wanted your guys to chime in.

I have no idea but I've seen vids of cars on dyno's and the rear wheel moves insane amounts when under load. Soft bushings will totally change things. Guys also change out eccentric bolts for solid ones because high load can throw off camber and toe when the bolt slips. Me being me I want everything solid to a point so if you can drive, I'm sure things are changing if everything's OEM.

Sounds normal to me. A little bit of lift off oversteer never hurt anyone. Except Porsches.

What you are feeling is normal for your set-up. It's a tight set-up. It won't release like a 1, or 1.5. What you have is good for drifting. Where both wheels will drive at the same speed.

I use accelrator and brakes to turn my cars? Perhaps this is first car you have had with enough power and stick to move with weight transfer?

You may just need to do some suspension tuning to better accomodate the LSD. Tires (amount of stagger) Spring rates, swaybars, damper settings, toe and camber can all impact how your LSD works too. Sounds like LSD is doing exactly what it is supposed to do.

while trail braking car should rotate nicely and backend come around, when u gas it just hand on for the ride LOL

nice vid.

Yeah, I figure its the soft bushings.

Im gonna install my gopro facing the rear wheel and under the car and go drive around, Im curious which contorl arm moves the most.

When you are in the power, BOTH rear wheels are trying to drive the car equally (and straight ahead at that), and if you have any steering input into the car at that time, the rear tyres are loading the front, so you inhernetly apply a little more steering input to tighten the turn in the direction you are steering.

If you jump out of the gas (abruptly), the car will feel like it "tucks" or "darts" back in and steers more that you;d think - that is just physics as you were applying a tad more steering to cover for the fact that the locked diff is trying to drive the car straight yet you still want it to turn.

If the rear suspension bushes as suspect, the LSD will be loading them as well, so you'll feel some rear steer as well.
