History
The 'Trans-Am series' was created in 1966 by Sports Car Club of America (SCCA) President John Bishop. Originally known as the Trans-American Sedan Championship, the name was changed to the Trans-American Championship for 1967 and henceforth. The series has in fact gone by a variety of different names through the years (too many to list), some linked to sponsors, some not. It has evolved over time from its original format as a Manufacturers' Championship series for modified passenger sedans and Coupés to its current form as a Drivers' / Manufacturers' Championship Series that is open to GT style racecars. Champion drivers have been officially recognized, and Drivers' Championships awarded since the 1972 season.
Over the years, the series has raced on a variety of different types of race tracks (Permanent and temporary road courses / street circuits / airport circuits) all over the country, as well as at venues in Canada, Mexico, and even San Juan, Puerto Rico in 2003. Since 2015, Trans Am has been a national series (Continental U.S. only), racing at tracks primarily throughout the East Coast, South, and Midwest. Since the 2017 season, the stand-alone West Coast Championship Series has raced at four tracks--three on the West Coast, and one in Texas that is a 'shared event' with the Trans Am Championship Series. Each Championship Series is independent of the other.

Tires / Presenting Sponsor
In 2017, Pirelli became the exclusive tire supplier (replacing Hoosier) and presenting sponsor for the Trans Am Series, and all classes use Pirelli P ZERO radial ply racing slicks. All Trans Am by Pirelli races go on even if it rains, in which case competitors may pit and change over to softer, treaded rain tires. The change from bias ply tires to Pirelli P ZERO radial tires has been very well received, and has resulted in faster average speeds and improved lap times in all four classes.
Car Classifications
Tube-Frame / Silhouette Body
TA
TA class cars are high-performance Grand Touring race cars with a tubular chassis and a Cadillac CTS-V, Chevrolet Camaro / Corvette, Dodge Challenger, or Ford Mustang body (full-scale replica) built by Advanced Composite Products (all eligible cars except Corvette C7) or Derhaag Motorsports (Corvette C6 / C7 / Camaro Generation 6 ["Gen 6"] only). Many of the entries carry Chevrolet Corvette bodywork, but there are several Ford Mustangs, a couple of Cadillac CTS-V coupes, and a Dodge Challenger in the class as well. All body types are eliminated 5 years after the last year that type or generation is produced. A minimum of two functional brake lights in their approximate stock locations are required on all cars competing in the Trans Am Series. They must be plainly visible, unobscured, and function just as they would on a production car.
Power comes from overhead valve (two per cylinder), pushrod, naturally aspirated, carbureted 358 cubic inch (5.86 L) V8 engines, producing anywhere from 850 to 875 horsepower. The minimum base weight (including driver and driver gear) for all cars is 2,780 pounds. Fuel cell capacity is 33 U.S. gallons. Current rules allow for the use of leaded gasoline, whereas all other classes must use unleaded gas. The use of Nitrous Oxide (or other similar compounds or systems), fuel additives, and/or fuel cooling, as well as supercharging or turbocharging is strictly prohibited in all classes. Automatic transmissions are prohibited, and manual transmissions must have no more than 5 forward speeds, and a functional reverse speed.
TA2
TA2 class rules specify a tubular chassis built by Howe Racing Enterprises, M-1 Motorsports, Mike Cope Racing, or Meissen Enterprises, and a Chevrolet Camaro, Ford Mustang or Dodge Challenger body (full-scale replica) built by either Five Star Racing Race Car Bodies (Gen 6 Camaros and Mustangs), or Howe Racing Enterprises (all other eligible cars), with the Camaro body being the most popular by far. A minimum of two functional brake lights in their approximate stock location are required on all cars competing in the Trans Am Series.
TA2 engines are similar to TA engines, but are fuel injected, and must use restrictor plates, as maximum power is limited to 490 HP. As per current rules, "Nothing may direct or force air to the filter or housing." Transmissions must be commercially available, 'H pattern' manual units with four forward gears (without overdrive) and a reverse. The minimum base weight (including driver and driver gear) for all cars is 2,830 pounds. The costs of shock absorbers, brake calipers & pads, and wheels are controlled, and no titanium or carbon fiber components are allowed, other than the driver's seat. TA2 is currently Trans-Am's most popular class among competitors.
Production based
TA3
The production based TA3 class cars must be of a number of different specified domestic or foreign makes, models, and year of manufacture, from American "muscle cars" to European exotics - such as Aston Martins, BMWs, Corvettes, Camaros, Vipers, Ferraris, Mustangs, Lamborghinis, Maseratis, and Porsches. As stated in the current rule book, The "...class is intended for recent model sports cars and new option engine Camaros and Mustangs." But "Additional cars having similar performance capabilities and fitting in with the overall concept of the class will be considered for inclusion in the TA3 class". Unlike TA4 cars, the current rules allow them to "...compete at a higher level of preparation." Standard body appearance must be maintained, including the OEM grille and badge. As with TA4, Tube frames are not allowed, and roll cages are mandatory. Some engines are required to have restrictor plates, for the purpose of equalizing performance. Minimum Vehicle Base Weights may be changed for the same purpose.
TA4
This class complies more with the "classic" Trans Am standards of the glory era. TA4 class cars must be a modern production-based Ford Mustang, Chevrolet Camaro, Dodge Challenger, Maserati Grand Turismo MC Trofeo/GT4, Porsche Cayman X51 Gen 2&3, Cayman GT4 Club Sport Gen 3, or 2009 - 2013 Aston Martin Vantage GT4 Gen 1&2. The class is intended to be a competition between late model, nearly stock, high-performance cars. It's an affordable class, and a good place for Trans Am Series beginners to start racing in. As with TA3, some engines are required to have restrictor plates, for the purpose of equalizing performance. Minimum Vehicle Base Weights are adjusted depending on optional components used.
*See current rule book for complete information on all Trans Am Series rules and regulations.
Schedules
Currently, there are 13 races on the Trans Am Championship Series schedule (9 permanent road courses / 3 temporary road courses / 1 temporary street circuit), with the Chevrolet Detroit Grand Prix presented by Lear race being open to TA and TA2 class cars only. For 2017, the schedule was reorganized, with five race venues (Homestead-Miami Speedway, Road Atlanta, Watkins Glen, Virginia International Raceway, and New Jersey Motorsports Park) receiving new dates, the Indianapolis Motor Speedway being added, and Louisiana's NOLA Motorsports Park being dropped.
In late 2016, the Trans Am Race Company (TARC) announced that after a long absence, the Trans Am Series would return to the West Coast with the 2017 Trans Am West Coast Championship, partnering with the Sportscar Vintage Racing Association (SVRA). The West Coast Championship Series consists of a separate 3 race competition, plus one round that is shared with the Trans Am Championship Series at Circuit of the Americas. (3 permanent road courses / 1 temporary road course)
Direction of Travel
In the Trans Am Series, the direction of travel on the racetrack is up to each race facility. It is usually "clockwise" (right to left, as viewed from outside the track), except at Homestead-Miami Speedway, Circuit of the Americas, and Daytona International Speedway. In the West Coast Championship, the direction of travel is clockwise at Willow Springs International Raceway and Portland International Raceway, and counter-clockwise at Auto Club Speedway and Circuit of the Americas.
Event Protocol
*Trans Am Series rules and regulations are extensive and detailed. The main rules relating to a Trans Am race are:
- Practice / Qualifying / Warmup / Race / Length
At each race, there are two practice sessions, one qualifying session, an optional warm up session, and the race itself. Since the 1975 season, Trans Am races are ~100 miles in length.
As stated in the current Rule Book, "The normal race length of Trans Am Championship, Presented by Pirelli Races are 100 miles (including the lap that completes the 100 mile length) unless otherwise specified in the Supplemental Regulations or otherwise changed by the CHIEF STEWARD during the course of the event weekend". The CHIEF STEWARD may also limit a race to a certain number of laps, miles, or minutes; whichever comes first. (See current Rule Book for complete information on race length and scoring)
- Multiple Class Race / Grid (Field)
TA, TA3, and TA4 class cars all "grid" (2 fastest qualifiers on the front row, slower cars behind them according to qualifying times) and race together during the same "race session" (as the rule book puts it), using a staggered start with the two slower classes starting their respective races (in order of class) behind the TA class grid, being separated from each other as well. The fastest qualifiers in each of the four classes may choose to start on the left or right of the next fastest qualifier on the front row. TA2 class cars have their own separate race.
- Race Start / Finish
The series uses a rolling start with (or without) the pace car proceeding parallel to the field, and in pit lane, approaching the Starter at the Start/Finish line, who uses a green flag to signal the start of the race for each of the 3 classes (or the TA2 field). In the absence of a pace car, or if additional pace laps are required, the "pole" car for each class will serve the same function as the pace car from its position in the front row. At the completion of the last lap, the Starter waves a checkered flag, signifying the end of the race. All winning drivers, as well as second and third-place finishers (plus any award winners announced over the official race control frequency) are required to attend the Winner's Circle ceremonies at the victory podium/rostrum.
- Fuel / Pit Stops / Tire marking / Tire changes
Trans Am Series racecars carry enough fuel to run the entire race non-stop, making each race a 100-mile sprint that is a test of driver skill and competitiveness. Current rules allow for TA class cars to use leaded (112 Octane) or unleaded (98 Octane) gasoline. All other classes must use unleaded gas. (All fuel is supplied exclusively by VP Racing Fuels, Inc.) Fuel and refueling on pit lane, or on the grid is strictly prohibited. Fueling / refueling is only permitted in the team's paddock space.
TRIVIA: The 112 Octane gasoline is green, the 98 Octane gas is colorless.
Pit stops are neither needed nor required, other than for the purpose of changing over to rain tires, or for some other mechanical or other issue. The pit lane speed limit is 45 miles per hour during all sessions (practice / qualifying / race).
As per the current Trans Am rule book, each team has four dry tires (slicks) per car marked by the Trans Am Technical Staff prior to qualifying. "All cars shall start the race on the same set of marked dry tires that they qualified on, or on the set of dry tires the team had marked prior to qualifying if rain tires (treaded) were used in the qualifying session." Teams are only allowed to change one undamaged tire per pit stop without penalty. All damaged tires may be changed without penalty, and a Trans Am pit lane official must verify the damage. Changing over to (or from) any number of rain tires is up to each Crew Chief, and is not limited.
- Flags
The series uses flags (six 'advisory' / seven 'mandatory compliance') to communicate with competitors during all qualifying, practice, and race sessions. A "Safety Car" is used to lead the field(s) during all Double Yellow Flag periods. All restarts are single file.
The Advisory flags are GREEN (beginning or resumption of a session, and that the course is clear), BLACK AND WHITE DIVIDED DIAGONALLY (shown once only to the Driver with a number board from the Starter as a Warning for 'Unsportsmanlike Behavior'), BLUE WITH YELLOW DIAGONAL or SOLID BLUE (advisory for competitor following you), YELLOW WITH RED STRIPES (caution, the racing surface may be affected by fluids and/or debris), WHITE (caution, you are approaching a slow moving vehicle), and WHITE WAVED AT START/FINISH LINE (last lap of competition).
The Mandatory Compliance flags are BLACK (shown to the Driver with a number board from the Starter and/or at designated flag station(s) on the circuit. The Driver must report to Series Officials on pit lane for consultation and/or penalty within four (4) laps or face possible additional disciplinary actions), BLACK WITH ORANGE DISC IN CENTER (shown to the Driver with a number board from the Starter and/or at designated flag stations on the circuit to advise of a mechanical problem that may endanger the Driver or other competitors. Driver must report immediately to their assigned pit at reduced speed and may not rejoin the session until released by the Technical Director or his designate), YELLOW (local / partial course caution - must reduce speed and line up in single file - no passing), WAVED YELLOW (use great caution!), DOUBLE YELLOW (full course caution - no passing), RED (the session has been stopped - use caution and proceed immediately to pit lane - no passing), and BLACK AND WHITE CHECKERED (completion of practice, qualifying, or race).
Championships / Awards
Originally, Manufacturers' Championship points were awarded in all classes to the top 6 finishing positions of each make of car: 9-6-4-3-2-1. Beginning in 1972, the SCCA instituted a Drivers' Championship that would be based on overall finishing position from 1st through 10th places: 20-15-12-10-8-6-4-3-2-1. Beginning in 1990, the top 25 finishers were awarded points as follows: 30-27-25-23-21-19-18-17-16-15-14-13-12-11-10-9-8-7-6-5-4-3-2-1-1.
Currently, Manufacturers' Championship points are earned in exactly the same manner they were originally. (*Vehicles must be classified as finishers to score Manufacturers' points.) Final point standings ties will be decided by which manufacturer has more wins, second-place finishes, etc., as necessary to determine the winner.
Series Champions in each of the four competition classes are determined based on points accumulated during the season. Drivers' Championship points are awarded as follows: At each race, after Qualifying has been completed, 3 points are awarded to the First Qualifier, 2 to the Second Qualifier, and 1 to the Third Qualifier. The top 24 finishers in each class, at each race are awarded points as follows: 30-27-25-23-21-20-19-18-17-16-15-14-13-12-11-10-9-8-7-6-5-4-3-2. All other finishers are awarded 1 point, provided they took the green flag at the start of the race. During each race, 1 point is awarded to any driver leading a lap in class, as well as 1 point for leading the most laps in class for each race. In all classes, the driver's lowest scoring race of the first five events will be dropped, and no Championship points will be awarded for it. (*A driver must be classified as a starter to score Championship points.)
Series Champions are awarded the brand new for 2017 Trigon Trophy (sponsored by 3-Dimensional Services Group, and custom designed by longtime partner Crystal Sensations). According to The Trans Am Race Company, LLC President John Claggett, "The base is shaped as a "D"... The crystal is essentially 3 sided... thus... the Trigon Trophy reflects the sponsorship. And yes... They are beautiful." The Trans Am Series' traditional colors are red and black, and Pirelli's color is yellow, with The Trigon Trophies incorporating those design elements.
Rookie of the Year winners in each class are also determined by points accumulated during the season.
After the results of each race are "final", the COOLSHIRT Systems "Cool Move of the Race" Award (If applicable, it is given to the outstanding driver of the race, and the "move" could also be a 'move up through the field'.), pitboxes.com Crew Award, and Traq Gear Crew Chief Award are given out.

Tributes
- The "Historic Trans Am Series" is "...simply a group of individuals who wish to share our appreciation for the great race series -- the Trans Am -- during its heyday from 1966 to 1972." Original racecars from Trans-Am's "golden era" are faithfully restored to original condition, and then "raced" at select events. They are a regular group at historic automobile racing events. In 2010, the Monterey Historic Automobile Races at Mazda Raceway Laguna Seca in Monterey, California paid tribute to the under 2000cc group. On occasion, the Monterey Historics and its former sister event at Sonoma Raceway, also in California, have paid tribute to 1980s Trans-Am cars, often referring to them as "IMSA GTO" cars. In recent years, the Sonoma event has referred to them as "SCCA cars".
- A few teams in the Continental Tire Sports Car Challenge, which is reminiscent of the old Trans-Am Series, have painted their vehicles to resemble the old Trans-Am cars. In 2010 Multimatic Motorsports painted their Ford Mustangs to resemble those of Parnelli Jones and George Follmer. Also entered that year was a modern version of the Sunoco sponsored Chevrolet Camaro.
- The Pontiac Firebird Trans Am was named after the series. According to SCCA archives, that brand has taken 7 wins and 1 Championship in the 42 year old series' 450+ events. The last win by a Pontiac Firebird Trans Am was in 1984.
- Tommy Kendall previously drove a Dodge Challenger using tribute livery modeled after Sam Posey's 1970 Challenger.

Other series based on the Trans-Am Series model
The Trans-Am Series has used tube-frame / silhouette cars, similar to the original IMSA GT Series, since the early 1980s, with heavy emphasis on GT cars. The SCCA Pro Racing World Challenge and Continental Tire Sports Car Challenge racing series, run by the Sports Car Club of America (SCCA), and the International Motor Sports Association (IMSA), respectively, utilize modified production-based cars, sports cars, and touring cars, similar in spirit to the Trans-Am Series series since the 1980s. With the rise of these other series, Trans-Am saw decreased attention from the media, however, Speedvision did occasionally cover Trans-Am races until the series' demise in 2006.
