Super Street Feature: 1000hp Subaru BRZ – Dai Yoshihara’s Evolution to LS

Super Street Magazine Editor-in Chief, Jonathan Wong, interviews Daijiro Yoshihara to find out how he got started in drifting and to talk about his Formula Drift Subaru BRZ; which has been outfitted with a turbocharged V8 pushing nearly 1,000hp and the Version 2 Rocket Bunny kit.

SS: What was your life like when you first started driving?

DY: I was 18 when I first got my license. I was already riding motorcycles with all of my friends because you can get a motorcycle license when you turn 16; you cannot get a driver’s license (for cars) until you turn 18.

 

SS: What was street racing like for you growing up in Japan?

DY: It was fun. I know I shouldn’t say that, but it really was. I would go with my senpais (mentors), who weren’t very close friends of mine, but they were really into drifting. This was kind of a secret life that I led (being a drifter); most people who are into drifting, their life revolves around drifting—not me. I had a separate life outside of it. Back then (late ’90s to 2000), drifting wasn’t cool, and it was considered kind of nerdy. The culture was very different.

SS: What was your first car?

DY: A Corolla, AE86. The same year I started drifting (’95) is when Initial D came out. It wasn’t even popular, but I was reading it. It was a fun comic but didn’t really influence me in any way.

 

SS: How did you practice?

DY: First I did donuts and figure eights like everybody else. I used to practice at these public bus stations; at night, they’re empty so they turn into big parking lots. Every single night I went and practiced.

 

SS: How difficult is it for someone to become a pro drifter in Japan?

DY: It’s not easy at all, and the bottom line is, at the time, even someone like Taniguchi was still a touge driver. There was no D1 yet. At that point, nobody, not even one person, except maybe Keiichi Tsuchiya, thought there would ever be such a thing as professional drifting. It was just kids messing around type stuff.

SS: When did you discover you actually had a talent for drifting?

DY: Around ’96-’97. D1 Japan started in 2000 and I didn’t come to the U.S. until 2003. In between all those years, I was a weekend street racer. I did the same thing over and over, practice, practice, and never thought anything would come of it. I went through five more cars after that AE86: a Nissan Laurel, Cefiro, 180SX, R32 Skyline four-door, and an S14.

 

SS: What was your favorite car out of those?

DY: I’ve always loved the AE86, even today. I want to own another one in the future. I didn’t really fix up my cars, though. That’s probably why I never had any problems. Just a simple set of coilovers and an LSD, change the tires, and put gas in. I like to drive a car as it comes naturally, more or less.

 

SS: What’s the most exciting thing about drifting? What scares you?

DY: The most exciting thing is to win. The fact that I even have a chance to win an event is very exciting as well. I’m scared of failing, and it sucks when I don’t do well.

SS: How did you wind up with the BRZ?

DY: My last S13 has aged quite a bit, so a few years ago the discussion came about for a replacement. From a sponsorship standpoint, it’s better when you have a newer platform to work with. The S13 is more like a classic now; if you want to build one now, it’s a little bit more difficult. Most of all, I wanted an FR (front-engine, rear-wheel-drive), and the only one that appeals now is the ZN6, or FR-S/BRZ chassis.

SS: What keeps you motivated to do your best?

DY: Myself—I just want to do well. It’s my career. Before it was a hobby, but now it’s my life. I have to pay my bills. Doing well now only helps to secure more for my future. I want to be the top drifter, and it’s been a while since I won a championship, so I definitely want to be back on top.

SS: Do you think your reason for being is because of drifting?

DY: Yes, I think so. I haven’t been doing well recently, but I always think things happen for a reason. I’m having a hard time, but I think I can overcome it—and without drifting, I wouldn’t have the life I have now. I get to live in the United States, and I have a lot of friends because of my drifting career. I wouldn’t be in Super Street if it wasn’t for drifting. So yes, it was meant to be.
