The Red Dragon: Daijiro Yoshihara’s Discount Tire/Falken Tire S13Inside the car, the interior is all business. The roll cage has been updated by SPD Metal Works to comply with the latest safety requirements and is reinforced to ensure maximum safety of Yoshihara in the event of a collision. A pair of Sparco seats and harnesses keep both driver and a potential passenger in one place at all times, while Yoshihara’s inputs are handled thru the Nardi steering wheel. Outside of the Pride Performance Carbon dash, custom switch panel between the seats to handle ignition and other duties and the Motec dash display, the interior is void of most creature comforts normally found in an everyday street car.

The magic of this car comes together through the suspension, namely with the tuning of Falken suspension aficionado Mike Kojima. Each corner sits on a set of KW Coilovers with custom spring rates and valving designed to maximize squatting under acceleration but stabilize the car once it’s pitched sideways. A combination of Nagisa lower control arms, SPL tension rods and rear control arms, and custom spindles provides the combination of adjustment to fine tune the caster, camber, and toe to the precise settings of Master Kojima to maximize the grip out of the Falken 615K tires. At each track, the car is dialed in for the type of track surface and judging requirements that have been set forth by Formula D staff. While we’d love to give you the specific settings Yoshihara uses at each track, we’d then have to kill you to prevent the information from getting back to other Formula D teams.

The latest makeover of the exterior of the car is definitely the most attractive. Drifting fanboys flock to the 6666 Customs Rocket Bunny bodykit, which is incredibly difficult to find here in the US. Yoshihara has always been partial to the dual-brick projectors from the S13, and this year’s look integrates custom smoked headlight covers into the front end. SPD modified the hood to integrate a hood scoop in an effort to keep the engine bay cool, fiberglass doors replace the OEM steel units to save weight, and an APR front splitter and rear spoiler endplates help stabilize the car at high speeds. The entire car features a custom graphics package which stays true to the original Rocket Bunny liveries that have become the staple of the brand. Finishing out the look, a set of 18” Yoshihara Design D59F wheels are the first wheel of Yoshihara’s signature brand, set to be released to the public later this year.

The Red Dragon: Daijiro Yoshihara’s Discount Tire/Falken Tire S13

Last season, Yoshihara piloted the car to two wins in Atlanta and New Jersey as well as a second place finish in Vegas on his way to a fourth place overall finish. While many would be happy with that, the team is aiming for a season championship with the car, knowing that all pieces to the puzzle are there to make it happen. Yoshihara has finished in the top five of the championship in six out of seven Formula D seasons, proving he’s one of the best on the grid.
