Circuit Showdown is a Philippine auto racing series that began with its first racing season in 2010. 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 provides medical assistance to every event.


2012 will see some more changes in regulations particularly in the Grid Races tire restrictions were imposed. The complete list of the regulations can be found on their website for both Grid Races[1] and Time Trials.[2]

This season, will debut the Champions of Champions race where champions of each bracket are invited to race in identical cars for the title of "Champion of Champions." Also, participants that will be running this year's tire sponsor, GT Radial, may compete for the title GT-R Champion and a set of high performance radials.

Race Format[edit]

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 with Grid C; 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, with Grid B then Race 3 with Grid A. 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.

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

Time Trials[edit]

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[edit]

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

The series runs throughout the year alternating between the major race venues in the Philippines, often changing the layout to add variation. One of its venues is the Clark International Speedway (CIS), the newest touring car race track in the Philippines. Its completion in late 2009, and continuous expansion has made this track the most competitive to date. The Batangas Racing Circuit (BRC) was created in 1996 from a 2.9 km circuit it has grown into a 3.5 km track with a 550m straight also used for drag racing events.

In 2010, the series ran a few legs on the now defunct Subic International Raceway (SIR), a 2.9 kilometer circuit with 12 turns, that has been the venue for both local & international races. Located beside the Subic International Airport, it is 15 minutes away from Central Business District of Subic Bay Freeport and was completed in 1994. Early in 2011, the track has been closed to make way for a commercial development in Subic. As a send-off, the administration of the Subic Raceway organized the "Last Lap," a three-day event open to everyone.[3][4]
