It is currently the only circuit racing series in the country that is open to both amateur and professional drivers that features a classic Touring Car series as well as a Time Attack Competition. Each driver and his vehicle is equipped by an AMB timing system to accurately measure their lap times. Drivers are ranked by their qualifying times and bracketed to compete; accumulating points to vie for the championship in each of the six brackets at the end of the season. The series is open individuals and teams from various racing backgrounds welcoming cars from daily driven stock cars to full race cars. Each event is hosted at different race venues in the country. Open to the most amateur of drivers, the organizers provide driving aids from the country's leading race professionals during the event. In addition, the Philippine National Red Cross

Regulations

In 2011, minor changes in regulations were made including the restrictions in tire tread ware rating. The complete list of the regulations can be found on their website for both Grid Races and Time Trials.

Race Format

Typically, the event is scheduled on the first Saturday of each Month. Each leg is a whole day event that varies from track to track. The track opens early providing participants with an open practice and enough time to test the track and tune their cars. The event formally begins with a compulsory drivers' briefing then the Qualifying sessions for both Grid and Time Trials (TT) commence and ends at mid-day. Time sheets and bracketing are posted immediately over lunch so everyone can see their qualifying times that they did in the morning. This is followed by the grid races; Race 1 starts for Grid A & B followed by Grid R; once the track is cleared, Official Time Trials Begin for all six brackets. After the last of the TT cars have run, Race 2 follows, often with a reverse grid position. There are cases when the schedules are shortened or revised. These changes are announced on their website and Facebook Page typically weeks before the event.

Bracketing

Each participant is grouped into their respective brackets based on their performance on the Qualifying Session. Once participants qualify in a bracket, they can no longer go to a lower bracket and compete in that bracket. They can however "break-out" or move to the next higher bracket. Races continue even during rains; in these conditions, bracket times are adjusted and are discussed during the briefing. Below is a sample bracketing for the 6th Leg held at Batangas Racing Circuit with a reverse layout and dry conditions

Group	Time Bracket
Bracket A	00.00.000-02.04.999
Bracket B	02.05.000-02.07.999
Bracket C	02.08.000-02.10.999

Bracket E	02.14.000-02.16.999
Bracket F	02.17.000-03.00.999

Time Trials

The series features time trials for those who want to run their cars against the clock. There are a total of six brackets where a participant can compete. The goal of each participant is to reach the closest time set on the bracket, if time is beat, a maximum of .200sec is allowed but will void the fastest time, in this case the 2nd fastest time will be used. For times of .201sec or better, the participant is moved to the next faster bracket.

Grid Race

Grid race are for those who want to compete "wheel to wheel" with other competitors. They are grouped into three categories. Grid R is for the race car class, Grid A are for the cars that qualify in brackets B, C & D, and Grid B are for those who qualify in brackets E & F.
