one big thing, well, a couple things. You want harder springs on the outside, so the car doesn't shift as much, and keeps as much of the inside tires planted. Softer springs will along you chassis to sway to the right, which will make it hard to drive. Here is a little setup thing:
hard right springs
heavy oil right side, i'd go with 60-70, maybe 50 if you want it twichy, and the corners are tight.
wide tires, if not, wider outside tires, a cool little thing, never tried it, but it works in sprint cars, lol.
battery as far inside as possible, even grind some of the tunnel, it's a big thing.
basically, make you car very fast, and lower it, i also advise you to glue the outside edge of the tires, going fast, and turing sharp corners, could make it traction roll.
