Depends on the level of bite....On Carpet, bump-toe on the outside front wheel makes the car steer in more off-power. The weight transfer to the front-end makes the outside wheel turn in harder, inducing MORE steering. If the car has the ability to "drift" across the track,i.e. "low-bite/asphalt", the car won't feel the same turn-in effect. Hence the reason that alot of MOD carpet racers run the servo flat, while stock racers have generally tended to prefer servo up. Mod REQUIRES more turn-in because of the greatly enhanced speeds.
