MotoIQ Pacific Tuner Car Championship Rules
2011 Rules and Classifications

DRAFT!

1. Introduction

The MotoIQ Pacific Tuner Car Championship (MPTCC) was created to meet the needs of Sport Compact racers looking for a wheel to wheel racing series specifically tailored to accommodate modified vehicles which are currently relegated to racing uncompetitively in Unlimited classes due to the addition of common popular modifications for street tuned cars. This class is designed to unify fields of cars that currently race in or are classed un-competitively with other sanctioning organizations. This large field/open modification concept will provide racers and performance market manufacturers a creative racing class that can run nearly unlimited aftermarket-created configurations.

2. Intent

The MPTCC Rules will encourage each competitor to create an aftermarket-sourced configuration that will make their car perform at an optimum level. The intent of the rules is to allow competitors to use any commercially available parts that will increase the performance and competitiveness of the vehicle and create promotional exposure for that vendor. It is the intent of the series to serve as a “showcase” for aftermarket tuners and manufacturers and to create tremendous exposure for their products and services while providing a friendly, accommodating, and challenging environment for the series drivers. This approach is intended to create a reciprocal relationship that will encourage the aftermarket tuners to give their support and attention to the competitors in the series.  Additionally, this series is intended to provide an affordable introduction to competition with an emphasis on sportsmanship and advancing driver skill. 

3. Sanctioning Body

The MPTCC will be supported and sanctioned by Redline Time Attack. All race events will be governed by the rules set forth by the MPTCC series directors and Redline Time Attack officials. All competitors agree to also abide by the rules set forth by the Redline Time Attack organization and any supplemental rules issued by the MPTCC Series Directors. Any decision made by MPTCC Series Directors regarding the status of MPTCC competitors or their vehicles is final.

Skinning parts of the unibody that are not removable such as the quarter panels and roof with composites is not allowed. Air dams can be modified with splitters.  The splitter cannot extend more than 6" from the base of the air-dam.  A belly pan may be used but cannot extend past the centerline of the front axles.  Rear diffusers may be used but cannot start forward of the rear axles and extend past the edge of the rear bumper.
