I'm planning on going ice racing up at Georgetown Lake this upcoming weekend. The machine in question is my 2015 Subaru WRX. It is mechanically stock, with the addition of a set of Michelin X-Ice Xi3 snow tires; they're not ideal for ice racing, but they work just fine at getting me to work in inclement weather.
I've been once before, but it was several years ago in my old '06 STI. I'm not expecting to be fast, but any tips pertaining to hustling my Subie around the ice would be greatly appreciated!
For reference, the course I'll be on is essentially just an autoX on a frozen lake.
My WRX has "active torque vectoring", which is basically just brake vectoring, where it applies light brake pressure to an inside wheel in order to help the car rotate. From my last experience on the ice several years ago, I remember the words "terminal understeer" coming to mind. As such, I'm thinking that leaving the torque vectoring on would probably be more helpful than hurtful. Thoughts?
My WRX has 3 "modes":
1) Traction, stability and torque vectoring all on.
2) Press the traction button once and it toggles traction control off, reduces stability control intervention and leaves torque vectoring on.
3) Hold the button for 5 seconds and it turns all 3 systems off.
^^^Given my lack of ice racing skill & experience, I assumed mode #2 would be best for me. Am I missing anything?
Also, thoughts on handbrake turns? I remember the last time I went in my old STI there were sharp 180 degree pivot points at the ends of the courses where the car would just understeer to infinity... I remember using my handbrake to pivot the car around them, but I honestly don't know if it was the fastest way to get the job done or not. Thoughts?
These will be pretty low-speed courses. I'm debating if I should use 1st gear, or do most of the work in 2nd in order to decrease torque to the wheels? Not sure if the extra torque will help, hurt or a bit of both on the frozen lake.
Any thoughts are appreciated! Thanks in advance!
