THE CARS - Spec Focus (SF)
BODY STYLES - Various Focus body styles are allowed in Spec Focus which allows competitors to choose from 3 or 4 door hatchbacks, 4 door sedans, and the new 2008, 2 door coupes.
SUSPENSION - The allowed suspension modifications in Spec Focus enhance the steering and handling characteristics that helped the car win both the European and North American Car of the Year awards without going to extremes with respect to either stiffness or setup complexity. The production style spring and damper package was developed specifically for this application and provides maximum performance out of the box without requiring extensive setup or testing.
BRAKE - The SVT Focus brake package is legal for Spec Focus and provides 12" front rotors that produce excellent brake feel combined with lots of stopping power. In addition, because the brake kit is production based, spare parts can be obtained through any Ford dealer and racing specific brake pads can be obtained from a variety of sources. The large diameter of the brake package requires fitment of the 17" wheels offered on SVT models, of which there are several different styles with the same physical dimensions.
ENGINE - The engine packages and allowances in Spec Focus were developed to allow the different engines offered in the Focus over the years to be competitive with each other without excessive penalties in terms of weight or power. All engines offered in the North American Ford Focus are legal for Spec Focus except for the 8 valve SPI engine. This includes: 2.0 Zetec (2000-04), 2.0 SVT Zetec with VVT (2002-04), 2.0 Duratec (2005+) and 2.3 Duratec (2003+).
Engine modifications are specific for each engine variant and are designed to balance the combination of horsepower and torque to allow parity among all 4 engine variants on the track. Modifications range from minor bolt-ons allowed for the 2.3 Duratec to relatively extensive engine work for the 2.0 Zetec such as a ported cylinder head, more aggressive camshafts and performance intake and exhaust manifolds.
