I put 90 lbs in the trunk, over the rear wheels. This made no difference to traction.
This car already has plenty of its weight over the rear wheels.
The main issue seems to be a propensity to break traction too easily. This results in fishtailing more readily than one expects.
My opinion is the Torsen transfers torque too aggressively and too quickly for ideal winter traction.
Interestingly, once the torque bias ratio is exceeded by a significant amount the lower grip wheel begins to spin and then the TRC kicks in to brake that wheel, allowing more torque to transfer. If you find yourself with very good grip on one wheel and no grip on the other you will find the Torsen does a good job.
This occurs even with TRC switched completely "off". Even more interestingly, the Torsen will spin both rear wheels if you wish to hang the tail out. How the computer CDN differentiate (pun intended) these two driving conditions is , well, even more interesting.
The TRC and VSC are quite sophisticated for such a cheap car.
Apart from this tendency to break traction too early and too suddenly the BRZ is quite easy to drive in winter conditions. You just need a bit of room for the tail wagging. Driving in heavy traffic in very slippery conditions is far more exciting than it should be!
