With my Sunbird it was faster to start in second but had a V8 (F/S). Just need to brutalize the clutch a bit.
Been a few years but thought the WRX would be an issue.
Do you have a Wavetec ? LSD was essential for four wheel steering. (Could pin the nose on a pylon and just pivot).
That was definitely a horsepower course. Must admit I'm more of a squirrel.
