Close to 300 horsepower. Approximately 330 lb-ft of torque. Racing tires more than 12 inches wide. 6-speed sequential gearbox. Brakes with six pistons front and four pistons rear. Adjustable racing suspension.
This BRZ goes far beyond its showroom namesake! Faster, too.
Two years ago, Subaru Tecnica International Inc. (STI) announced plans to replace its Legacy-bodied race car in the GT300 class of the 2012 SUPER GT. That replacement was the BRZ GT300. Then with the experience of a few races in 2012, STI carried over the car for 2013 with aerodynamic and chassis tweaks that add to its competitiveness.
SUPER GT – Japan’s top series for sports car racing – enjoys a strong following, and that includes Subaru and STI fans. They cluster together at series venues to cheer on the #61 BRZ GT300, and they’ve been treated to a racing machine capable of capturing pole positions in qualifying and of winning races!
2013 SUPER GT
In the fiercely fought SUPER GT Series, R&D SPORT fields #61 BRZ GT300 for STI against other grand touring cars (sports cars) on Japanese, Malaysian, and South Korean road courses. The series is sanctioned by Japan Automobile Federation Grand Prix.
After last year’s eight rounds, #61 had two podium finishes – a 1st at Suzuka in August and a 3rd at Twin Ring Motegi in November. Drivers Tetsuya Yamano and Kota Sasaki finished 4th overall in the driver rankings.
In an up-and-down season, the STI BRZ had finishes ranging from 1st to 9th and one round that it did not finish. The Subaru Global website has individual reports for each of the season’s eight race weekends.
GT300 cars are based on the road-going versions of their namesakes. Almost every aspect of the Subaru BRZ was taken to extremes in building the BRZ GT300 – all in the name of higher speeds and improved handling.
Bodywork A close look at the hood and rear end reveals the car’s extensive bodywork. It includes (but certainly is not limited to) a huge splitter at the front, air intake and exhaust ducts across the hood and fenders, wheel arches extended above the hood, exhaust in front of the left door, lower aero body cladding, rear fenders full of vents, and two wild rear spoilers.
Interior All unnecessary parts of the interior were removed, replaced by a racing seat, roll cage, and other controls, parts, and pieces required for racing. The seat was moved back in the cabin to the B-pillar, improving driver safety and helping to balance weight.
Engine Under the hood, the BRZ GT300 engine is the proven Subaru EJ20, which has been tuned for road racing using technologies developed for the STI World Rally Championship (WRC) cars since the 1990s.
The engine uses a dry sump system, which has an external reservoir for oil. That helps give the engine a lower profile to lower vehicle height as much as possible.
The intercooler is front-mounted. The air intake is also in front, which enhances the ram effect of incoming air, consequently increasing the airflow through the air restrictor to the turbo for greater power development.
The crankshaft has been specially designed for strength and reduced weight. It’s the same crankshaft used in the WRC engines. Likewise, the steel billet connecting rods have been specially designed for reduced size and weight, as have the forged aluminum pistons.
The same main turbo unit has been used for SUPER GT through the last few years. Boost is regulated on turbo engines to maintain competitiveness with cars having large-displacement, naturally aspirated engines.
