Inside The Mind Of Mr. Miura
Creative roots

Not long ago we asked you guys to submit some questions to Rocket Bunny creator and aero kit superstar Kei Miura. After sitting down with Miura-san in Long Beach, we were able to get some rather interesting answers out of him.

Like a lot of designers, he’s not a man of many words, but through the interview we learned about everything from bosozoku cars to a secret design for a vintage Ferrari. Let’s get started…


When you were growing up, what did you want to become?

KM: I wanted to be a fisherman. Haha!


Where did the name ‘Rocket Bunny’ come from?

KM: I can’t even remember where the name came from, actually. Somewhere inside my mind…


Who and/or where do you look for your inspiration when designing?

KM: There’s no specific person I look at, but I get a lot of inspiration from the design of kyusha (classic cars).


Do you listen to music when designing your kits? If so, what kind of music?

KM: Yes I do. I listen to a lot of 1970s rock music. I like punk, ska and reggae and a whole lot of other music from that era.


Does the car’s shape influence what you have in mind for the aero kit?

KM: It has a big influence. I have to look at the car before I design the kit. Designing the kit itself is not hard, but to make it match with the car is the hardest part.


Are you thinking more form or function with your kits?  Do you seek to improve car performance at all or is it just an aesthetic?

KM: The looks is the most important part to me, but a bigger challenge is making a design that fits properly and matches with the car.


Where did you learn Rhino [3D modelling software]? Do you have any sort of college degree in engineering or design?

KM: I have no degree, and I didn’t really learn from anyone. It was all self taught.


We know you use CAD for your designs, but do you ever sketch or sculpt your designs by hand at any point in the process?

KM: I usually begin with hand-drawn sketches before I use CAD to get an idea of how I want to start the design.

Finding inspiration

What is the reason you choose a riveted style body kit versus a hidden mounting style body panels? Is that choice driven by utility or an aspect of art and design?

KM: The look of the design is big part of it, but at the same time having rivets actually has a purpose to keep the panels mounted. Using glue or molding FRP parts to the car carries a lot more risk.


Mr. Miura, what was the first car you ever put fender flares on, and where did you first get inspired to use fender flares in your designs?

KM: It was a Kenmeri Skyline.


Would you create a car without widened fenders, or are overfenders are something that need to be in the mix?

KM: Absolutely I can create a car without widened fenders, but I love the look of a wide car so it’s something I’ve done on many of my designs.


What made you take the rear bumper off of the S13 in your kit?

KM: The original car was designed for the Nardò Speed Trial, and I heard at those speeds the rear bumper can detach. So why not leave it off completely?


Do you always want to keep on using CNC and fiberglass to make your kits, or in the future do you want to venture into lower-volume production metalwork, or utilize other materials like carbon fiber or carbon-Kevlar?

KM: I’m actually working in some of those other materials now – not for the Rocket Bunny parts, but for some of the higher -end exotic cars, like the LB Works Ferraris and Lamborghinis.


How long is the process from paper to finished product ?

KM: From start to finish is usually around one month for most of my designs.


Do you have any specific set of requirements when you choose a car to design a kit for?

KM: This is the most difficult part of the process. I always have lot of ideas in mind, but choosing which one to actually make is the hardest part. There are many different factors that come into play.


I was wondering what got you into cars in the first place?

KM: I grew up around a lot bosozoku in my area. I thought it was cool, and that’s what got me interested in cars. There were so many of them. At the local police station there were so many impounded bosozoku cars that they couldn’t fit anymore in the parking lot. It was cool, haha!


Miura-san, what was your dream car as a child?

KM: I think kids are influenced by the cars that are around them, and for me it was absolutely the bosozoku cars I saw driving through my neighborhood.


Out of all the cars you have created, which one is your favorite?

KM: Definitely the Nissan S13. Especially the Silvia – it’s my favorite.

The past and the future

What was the first car you designed a complete aero kit for?

KM: It was actually a Ferrari Dino. About 25 years ago somebody asked me to design some parts and I didn’t know what kind of car it was for at the time. Turns out it was a Dino race car.


What is a car that you always wanted to modify but haven’t had the chance to work on yet?

KM: There are lot of cars I’ve wanted to work on, but right now the one I want to do most is the Porsche Cayman.


Is there any car you wouldn’t touch? (Something that you feel is already perfect)

KM: Japanese kyusha from the ’60s and ’70s are my favorites. The parts for these cars are already so cool, so I don’t think you can do anything that looks better than these original designs.


Would you ever like to work as a designer for an actual car company?

KM: No, not really.


Miura-san, any plans of branching out to make a car and not just parts?

KM: I would like to do some work with racing teams, but I don’t have any desire to build a car from scratch. The design process might not be hard, but my business is modifying existing designs.


What is your favorite motorsport?

KM: It’s gotta be vintage car racing – not the big events, but the more grassroots stuff. Does street racing count? Haha!


Outside of cars, what are your favorite things/hobbies in life?

KM: I like building things. Even outside of cars I like working with machinery and creating things.


Mr. Miura, your hair is fabulous! What kind of prepwork goes into that style?

KM: A whole lot of hair spray basically. Maintaining the shape is not easy!


Do you see any new trends or styles developing in the future for body kits?

KM: It might sound sad, but I’m worried car modification might go away after our generation. I’m not sure about the whole world, but in Japan a lot of people are getting less interested in cars. It’s tough.


What’s the next big step for TRA Kyoto?

KM: For now my plans are to keep doing as I’ve been doing. I have some big ideas in my mind, but I’d rather surprise people with them…

A big thanks goes to Miura-san for taking time out his schedule to answer your questions, and also to Aki Hashimoto for his assistance with translation for the questions and answers.

this was one of the coolest series of posts ever. Thanks a lot for offering us, the readers, a chance to ask a legend questions, and then for us to be able to read what we and our follow readers wrote. I enjoyed reading each question and his thorough and well-thought-out answers.



so genius

much originality

very smoking



It's the Hair....gotta have the Hair.


Thanks for picking his brain, it's cool seeing the people behind the work. Miura-san's worry about the future was particularly interesting to me as it was exactly what I think I noticed in Japan. I commented on it in Dino's article on Tomei's taking on the KA24DE (


Respect your work sir, keep up the good work


Perfect segment. I enjoyed this.



Gianluca FairladyZ

That's awesome! Thanks Speedhunters!


And here's a bit of Rocket Bunny from Russia =)


I'm now spotting two Mercedes Benz w201 in frot of Miuras lair...
what work will go into them? I can't get my mind of them!

Argh i wanna know -.- w201 all the way baby !!


I enjoyed reading this and I have a greater respect for Miura because of it.


Article was OK. Ever since this partnership between Kei and Speedhunters, his kits are all over this page. Don't get me wrong, I'm happy for Kei and the RB name, but it kind of ruins it in a way. RB kits used to be very rare to see, and when you did, it was just amazing. All of this exposure is just turning it to "eh, seen it" status. Maybe I am old school, or being a hipster, idk.


AlexanderUlanov  failcrew?


Miura-san listens to 70's punk, ska and reggae? That part really made me say "whaaaaat??" lol there is nothing wrong with it, it was just not expected. 

i thought they got the name for rocket bunny from miura's nickname "kid rocket" and his wife "bunny". i don't know where i got that from. hahaha

great article, he seems like a great guy who is down to earth.

is speedhunters going to do an Q&A article on Nakai-san from RWB? or Kato-san of LB?


AlexanderUlanov  Front fender flares look bigger than the original kit that I see people having.

cool guy

turbo BEAMS ae86

@Jake Laird keep it on reddit


Would love to see that Ferrari Dino, links anyone?


Trying to be cool about it, but Im geeking out, like your average Fan boy that my question was answered. Thank you, sir.


Tinj  Yeah me too. That was a tease.


I really want to see him do something out of his usual cars, like a rocket bunny american muscle? I think he would love it given the muscle cars are wide already.


Does he manufacture his parts in-house too or just design them?


JeffAttala  Hi Jeff, if you click on one of the hot link tags, you can see other stories about the TRA Tokyo shop that has been visited by Dino numerous times. He designs and foam cuts moulds in house.


You know who Mira reminds me of especially with a Cig? Spike from Cowboy Bebop haha




Thank you guys for this great read. Stoked that you guys got to use one of my questions.


Make NSX Rocket Bunny kit, k thanks =)


AmriYusof AlexanderUlanovyes, from St. Petersburg.


David V  lol you're onto something! Maybe Miuras hairstyle is inspired by Spike ^^


chrislue7  the car is already so sexy tho lol


i wonder if he's ever gonna work on an american platform, The New mustang looks like a great platform for his body kits.


I'd really like to see that Dino Miura-san spoke about...


Onecton David V  funny that the hairstyle question got asked.  maybe Spike was inspired by Miura?  :)


Not a very challenging interview. Soft ball tosses, kind of a shame. Hopefully he finds a way to reinvent his designs rather than further risk diluting his brand.


wheatgod  crazy right? we draw so much influence from them and at the same time their car culture is dying faster than ours here in the states. We as Americans always need to let them know how appreciative we are of everything they have created.


shazzy_ed chrislue7 I agree, there are a lot of rad kits for the nsx already.


@ARIELSON I know this reverses some work done to stop smoking, but damn if he doesn't look cool in that first picture haha.


@tom I too read that its about his wife bunny.


I agree, he looks pretty boss...U0001f60e


How would i talk to him? About putting a build idea in his head. To bring a car thats not to over looked at and make it turn heads. For people who love to build.


Hey get back to me some how! Online! Facebook. "Devon kyle goulding"
I want someone to drawl up a bunny kit for a 2004 accord


2 door.
