Turning TRD LSD from 1.5 - 2 way

[KinLoud]

I think the recommendation is 1.5way for front wheel drive or rwd
2 way recommended for rwd only (can cause big understeer on fwd setup)
Really depends on your personal prefence - drifting go for 2 way as it can hel you get a drift angle on downshift.
Be very careful with 2 way in the wet as it will cause oversteer if you don't match revs on the downshift! Just like my locked diff on my racecar in the wet (rwd carina)!!
I don't really see how selecting 2 way would make the diff stronger?

Yea, 1.5 way and 2 way isn't anything to do with the strength of the diff, its to do with the properties of acceleration and deceleration.

Generally, (and it is very general) a helical is better for the hard surface - more forgiving on the other equipment - and a mechanical, or plate type, is better for loose.
That's the theory.
In practice, I'd go for the mechanical in all motorsport applications.

A couple of points.

If anyone is running a TRD LSD in a FWD in 1.5 way I'd suggest they remove it and turn the ramps to the 2 way setting.
Likewise, have your installer do this before fitting a new one. Otherwise it may break.

And the aw11 basiclly runs a fwd box etc...

I know that he said to do it mainly for motorsport use....but I want this car to handle what even I throw at it...

I'd be more worried about sticking the C52 box behind your motor. An E series box would be stronger.

e series means changing mounts....

possibly.... but remember you are supposed to brake/slow down before the corner anyway...

But I still dont know how to do it, and the engine is going in today so it will most likely stay in 1.5 form till I next pull it out.

yea well sh*t happens when your tuning sometimes cyclist, crash, mud, etc

fwd is really cool to drive with an lsd because you point the wheels and thats the way the car will go. you can pivot the car about the front wheels which is kinda cool. Also coming in hard on the brakes is no problem as you'll always be spining both wheels the same speed and be able to turn sweet, unless you break traction...

rear wheel drive I dont have much experience but I would imagine you would have to place the ar*e into the position you want to be going then squirt it out of the corner. maybe ask vvega?

i found when my diff was working correctly, that the car would understeer as the diff first locked up, then you could dial in more power as you'd like and it would turn-in on its line from there. i always had the inital moment of lockup tho when the nose pushed wide.
you also get the issue of the fact that, once you spin both both wheels in an lsd equipped fwd, you lose all steering until you back off and regain some grip, and as a consequence the nose will push wide under wheelspin.
they are great right up until you spin the wheels tho
and slightly more on topic , the trd mechanical items arent indestuctible, i seem to have worn mine out to the point itll hold almost 170wkw but open up completely at 220wkw.
this could be a result of either sustained use at higher power levels, or the time i was forced to do 50km on a spacesaver 3" smaller than the rim size it didnt particularly like that

-found out yesterday e series boxes are shitloads heavier too
