This weekend, Subaru and STI took the new 2016 BRZ GT300 out for a test run to get ready for the season opener in April. The team took the car to Okayama International Circuit to check out the new race car and the new changes. STI made two critical upgrades on the new BRZ GT300 to make it more competitive this season. The test session was attended by more than 40 cars.
What changes did they make?
Subaru Tecnica International (STI) made critical changes to the tires and aerodynamics this off season. They first made upgrades to the BRZ’s chassis. STI switched the front tires from 300/680R18 to 330/710R18 to enhance cornering and braking. The tire width and outer diameter is now larger at 30mm. This was done in an effort to reduce understeer in a continuous tight corner.
BRZ is more aerodynamic
The second big change comes with improved aerodynamics. The enhancements came as a result of testing in the wind tunnel and using computer simulation to see where they could make improvements. Changes were made to the headlights, front fender and to the rear of the car. The side mirror size was also changed and it’s now mounted lower on the body. STI says the mirror size and relocation alone improved air flow toward the wing, and has improved rear downforce.
Other refinements include an even lighter body and enhanced engine performance to the 2.0-liter boxer engine. The SUPER GT Series is widely regarded as Japan’s top motorsports category, and STI will again compete in the highly competitive GT300 class.
More testing will be conducted next weekend at Fuji Speedway to get the new car ready for the opener. Takuto Iguchi and Hideki Yamauchi will pilot the newly-upgraded 2016 BRZ race car again this season for Subaru. The first race will be on April 10 at Okayama International Circuit. Will these two changes be the difference? Stay tuned.
Here’s a recap of last year’s season for the BRZ GT300.
