LSD?
 
Our cars come with a Torsen LSD, right? So technically, shouldn't my car not be doing this?

Is this because I turned off traction control?

I believed the way the torsen works if one tire completely loses traction like that it acts as a open diff.

"If one wheel were raised in the air, the regular Torsen units would act like an open differential, and no torque would be transferred to the other wheel. "

Spot right on! Looking into AWD soon ? :bellyroll::bellyroll:

Pull your e-brake, you'll gain traction.

This is new to me, thanks for the tips :D . How does the FRS fare in the Snow and winter ?

The thread name mislead me .......

Best car I've driven, except maybe my WRX lol.

The brake trick is something I read on 4x4 forums - they are usually the ones stuck with a wheel in the air.

Yep, that's going to be normal, even clutch types will do this somewhat, depending on how strong they are. If you get an aftermarket clutch type, it can pretty much have no traction on one tire, and power the other. But that doesn't make it any better in the snow.

I came from an STi to this, so I'm not used to this! hahaha.

My KAAZ when I broke driveshafts would also free spool. Even clutch type needs some resistance for wedges to work. Our torsens are torque multiplying, 4 times I think? Four times 0 is still 0.

For a RWD car, this is pretty good in the snow. Just get a good set of winter tires, not all-seasons.

Nah, its about average. What makes it "good" IMO for snow is the weight distribution, and the fact it has no power so the accidental slippage of throttle won't do much.

Off topic, but what suspension are you running? :drool: Your car sits perfect!

RAWR BRZ 05-23-2013 04:08 AM

Actually... if that happens the TSC is suppose to kick in and brake a little so the wheel on the ground will have traction... thats what mine does... but if I do the pedal dance the TSC wont turn on and do exactly what yours did.

Even if you have TSC off it shouldnt do that... only after doing the pedal dance your car wont do that.

Yeah, I would hope that they would have designed the TC/VSC to brake the lifted wheel in those situations to let the LSD work. But yes, I imagine you have to hold the throttle and let it spin a bit to activate. That's definitely the major disadvantage of a Torsen.

Mine acts almost immediately with flashing lights on the dash and the car jerks like hell like it is about to break something :iono:

Sounds about right..

Loud noises also, right?

For Scandinavian conditions, and the cars most people drive here, the Toybaru is below average on the following conditions:
Ice/packed snow: Suspension too hard, and the AT shifts too hard even in "snow" mode, AT must be manually locked in gear to avoid accidents around corners and up/down hills.
Loose snow/slush: Too low ride heigt, even at stock, floats and loses traction.

Conclusion: The Toybaru is not unusable in winter, but compared to most new Subarus and Toyotas sold here it is not a good winter car.

I will nonetheless enjoy driving my GT86 through the winter, and I will be constanly looking for empty, iced parking lots... :bellyroll:
