DRIVER PROFILE
Pushing the limits of NA time attack -
To extract the full potential of naturally aspirated engines
A Japanese time attack driver who pours his passion into the sport.
After winning the Mazda ND Cup, he took on the challenge of endurance racing.
I have experience competing in the Carguy Lamborghini Super Trofeo at Motegi.
After that, they shifted to time attack and developed the 4-rotor RX-7. While steadily improving their lap times at Tsukuba Circuit, they also participated in the 86 Cup Pro class.
Through years of testing, aerodynamic development, and continuousmachine evolution,the goal is to achieve the fastest naturally aspirated time attack car .
WTAC debut in 2025.

MAZDA ND CUP
Mazda ND Cup – One-Make Race
The Mazda ND Cup is a one-make race series using the Mazda Roadster. Because the car performance is uniform, the winner is determined by the driver's skill, race strategy, and consistent lap times.
Hiroki Kamakura also participated in this series, honing his skills and gaining experience in intense close-quarters combat, and ultimately winning the ND Cup championship in 2017.
6 HOUR MOTEGI
Yuuki Kamakura competed in the Motegi 6-Hour Endurance Race in his four-rotor RX-7, pushing both driver and machine in a demanding long-distance format. Managing pace, strategy, and reliability, he secured a 6th place finish, gaining crucial experience in endurance racing that would later influence his approach to time attack development.
12 HOUR MOTEGI: IDLERS
Participating in the Idlers 12-Hour Endurance Race
He competed in the Motegi 12-Hour Endurance Race with Carguy's Lamborghini Super Trofeo. Driving a high-downforce GT machine, he gained practical experience in tire management, endurance race strategy, and high-speed race dynamics.
TOYOTA 86 CUP
Yuuki Kamakura competed in the 86 Cup Pro Class, a highly competitive series for the Toyota 86, focusing on driver skill, chassis balance, and precision. Facing experienced racers, he gained valuable insights into setup refinement, racecraft, and vehicle dynamics, applying these lessons to further improve his four-rotor RX-7’s time attack development.
12 HOUR MOTEGI: IDLERS
Train on the circuit and prove your worth with lap times.
YS PRODUCE's aero development is primarily driven by real-world testing at Tsukuba Circuit. Using a 4-rotor FD as the development vehicle, the design, verification, and improvement processes are repeatedly refined based on driving data to maximize stability and aerodynamic performance at high speeds.
WORLD TIME ATTACK SYDNEY MOTORSPORT PARK
In 2025, we took to the world stage for the first time, participating in the WTAC held in Sydney, Australia.
Competing against the world's most advanced time attack machines elevated the team and the 4-rotor RX-7 to a new level. Having gained invaluable experience, we returned to Japan, and will take on our next challenge with a more refined setup than ever before.
Furthermore, thanks to the support of the WTAC team, we were able to secure our first major sponsorship with HARDTUNED at this tournament. I am truly grateful for the trust placed in my work and the opportunities it has given me.
My goal remains unchanged.
We will continue our challenge, aiming to create the fastest naturally aspirated machine in Japan.
TSUKUBA CIRCUIT
NA TIME ATTACK
And in 2026, we will achieve the goals we have set forth for many years.
It recorded one of the top lap times for a naturally aspirated engine at Tsukuba Circuit.
