I watched a few vids of cars at some Goodguys events doing their mini autocross track for fastest time. This interests me a bit planning on the upcoming Goodguys at Kansas City Speedway. On a tri-5, what would be the most bang for the buck upgrades to making one handle the orange cone hiway? I don't mean spending oodles of money on an Art Morrison chassis, but just some basic upgrades. I already have disc brakes.
