Nearly stock with only a couple minor modifications. The stock motor mounts were not up to all the wheel spin and wheel hopped until they broke, so I put in some beefy aftermarket ones. I also put a slightly stiffer rear sway bar to get a bit more rotation.
Rallycross is a great way to see just what entirely ordinary cars are capable of. At the last couple events I went to a great driver in a lightly modified Sentra was faster than the people with fully built rally cars with twice the power.
