The Fiesta ST makes a pretty incredible autocross car.  The car places in the H-stock category, however, it is at the very top of its class.  The car is light weight, has a significant amount of power and dances through turns.   Its main competitor is the Golf GTI which had a history of dominating the H-stock class up until the Fiesta ST came out.

Liquid levels need to be checked and the tire air pressure adjusted to the proper level.  Once these are taken care of the car is ready to go, just remember to turn off the traction control.  The one unfortunate aspect of this car for autocrossing is its inability to disable ford’s torque vectoring system.  That being said the system helps more than it hurts; there are very very few drivers who could get more performance out of the car with it off.
