Building a Custom Fastback for the Cyberpunk Miata! Part 1

Today we'll finally be starting work on the new roof for the Cyberyata!
This is part 1 of a mini series I will be doing where I go over making a fiberglass fastback from scratch. This first video covers the basic form shaping using expanding foam and then smoothing it all out to make a finished plug / buck.

Randomly popped up in my recommendations. No unnecessary comments...just pure art and craftsmanship. I tip my hat to you. Can't wait for more :)

[@jase_llan]

Couldn't have put it better - nice, easy to watch video with great content.

[@saekabura]

People in the garage made fun of me for using foam for the base shape. They've never touched fiberglass in their lives 😒. Also amazing work, you make it look easy. Get yourself a ventilation fan

[@TofuAutoWorks]

I find a lot of people that are unfamiliar with how these parts are made think the foam stays on the car permanently. Hopefully videos like this should help clear some of that up. When I'm not filming I have the fan going but it's so loud that you cant hear anything with it on. When I set up my new workshop hopefully later next year I'll be designing a proper HVAC system. Thanks for looking out for me bro, appreciate it!

[@cj94zj92sc]

That and people making fun of using aluminum tape

[@the_nondrive_side]

Even the pros use foam. Just often it's block not spray foam. More recently it's printed. I'm a pro. This is as good as anybody

[@Caz885]

People who laugh just dont understand how to build things. Or understand anything.

[@andylewis7360]

@@TofuAutoWorks The creaking timbers add something extra 😁

[@chrisbrookshire861]

This Miata is turning out awesome. I really like the shape of the fastback you’re making. I would recommend picking up a 20” box fan with the controls on top. Then you can pick up 20x20x1 furnace filters and tape them to the back of the fan with duck tape and they’ll help with getting some of the dust out of the air. And cheap to replace the filters.

[@mattr4078]

Amazing work! I don't know if this is what your going for but it almost looks like a baby RX7 XD

[@gearzpop8457]

I think having a hose to a shop vac or a bag on that sander might help with the dust. It looks like its just dumping the dust into the air.

[@crowdie423]

What a lucky car! He has a such a badass owner :)

[@cybertwingo]

Can't wait to see the final result!

[@Airon0727]

I’m into motorcycles a little more than cars but I’ll be following this build!! One of the great motorcycle builders Indian Larry would say he believed that custom hand built bikes were one of the highest forms of art because it involved many mediums like sculpting, painting, leatherwork, etc.. all in one art piece. That’s obviously true with custom car builds like this as well.

[@harleykerstancantrell9835]

This is one of those videos I really didn't want to end... LOVE IT!

Great video dude. No boring KZbinr talk, just awesome work.

This channel is highly underrated This guy needs more subs right now❗ The production quality of the video is great plus the videos are fun to watch. You earned a new sub👍 And keep making videos no matter if you get any hate comments or not💪🏼

[@TofuAutoWorks]

Cheers man! Thanks for the kind words. My builds often get a strong love or hate response. I'd much rather show people that it's better to express your own style than to try fit in with all the same old cookie cutter builds.

[@TofuAutoWorks]

The roof shouldn't take much longer to finish but the car itself is a constant evolution. You can see how it has changed so far over on my instagram @tofuautoworks.

[@MHermansson]

@@TofuAutoWorks Sick! Will check it out!

[@gregkrueger331]

A little tip if i may, instead of sanding it down with an orbital, use a slightly over damp sponge. You’ll be able to smooth it out pretty good, plus the slurry created fills your pin holes to save a little bit more work on your filler stage.

[@TofuAutoWorks]

Thanks. This was my first time working with jointing compound rather than auto body filler so you can see how I'm used to working. What I didn't show in the video was the extra 5 passes of filling and sanding to get it perfectly flat and in those later stages I did start to figure out that if I wet all my tools then I can smooth it out a bit better.

[@gregkrueger331]

I grew up in the era Miata owners were made fun of for driving a girls car. However, this is the coolest Miata I’ve ever seen, next to the Hellcat Miata that is lol. Love that you’re not afraid to just dig in and do it, and do it well. You earned a new sub buddy. Keep up this awesome content, btw, you’re hella talented.

[@dim9988]

Man great work! I was thinking that looks a bit rx7 fdish and then i saw your reference photos and i was like that's a man of taste!

[@MrCbell57]

Awesome all the work that is required to do this for a little bit of shape change. It just doesn’t make sense to me logically. But then think of all the car designs that were made out of huge blocks of clay in the beginning.

[@MrIntercoolers]

Wow. Great job. Thanks for sharing

This is awesome, I love the expanding foam shots! Car looks great, it really suits the look.

[@TofuAutoWorks]

Watching it take shape is always super satisfying. The whole thing is going to be incredibly sleek once it's done, it's gonna really change the look of the rear end.

Cheap box fan, cut big holes in the front and back, put a house air filter in there with the fan. That should help collect some of that dust. Looks good so far 👍

[@kingmaybus8409]

I remember back in the superstreet days I always wondered when spoon made that Fastback kit version for the S2000 what that would look like on a Miata add wide quarter panels and a integrated ducktail spoiler and you kind of have a Aston Martin Vantage vibe in the back mini verion 😅🎉

[@nickpotts5378]

Spoon didn’t make it it’s a mooncraft piece

Man, I didn't see yet the next videos but these shapes look sexy!

[@gustavolopesdebarros4802]

amazing project, greetings from Brazil

[@feral4mr2]

Awesome work man! I was going to build a fastback for my mr2 spyder, but I just don't think the spyder shape pulls it off as well as a mx5 does. So now thinking something like a Porsche 918 spyder.

[@GlassWerx]

Amazing work. Actually thinking of making a widebody kit for my ek sedan using the foam method. Subbed. Can't wait to see more

[@sergiort7991]

I didn’t know you can use foam for the shape, you made it look like a pro sometime the fiber glass is hard to work on plus the time you need to invest is higher

[@WeekenderGarage]

hell yeah!

Hey maybe it's a stupid question but does anyone know what are these wheels ?? They look absolutely gorgeous !!!

[@travdripdrip382]

Very cool

[@HutchinsRacing]

So glad someone else is attempting this! Excited to see the results. Patience is key. Do you plan to make the final top out of fiberglass or carbon?

[@TofuAutoWorks]

The finished roof will be 100% fiberglass but I plan to start adding carbon fiber elements slowly as the build progresses. I already have the carbon and materials I just need some smaller molds to start experimenting on.

[@OG-Silesian]

nice

[@banzaiman1]

Looks good but your entire garage will now have a thick layer of dust on absolutely everything. Defo get a vac connected to the sander

[@fpaoli508]

What about clay and 3D scan?? Congrats mate, it is a lot of work!

[@TofuAutoWorks]

I havent tried clay just because it's so hard to find here, but when I designed these flares I did have them 3D scanned to mirror the other side. Unfortunately NZ isn't really set up to get this size part machined into plugs for reasonable money.

[@RandomGuyWithaMazda]

obligatory "KANEEEEDAAAAAAAAA!"

I'll have to find somewhere new to put the pill once I finish this new roof.

[@skylarpenn7825]

This is fantastic. Can I ask what brand the foam is

[@AIM2790]

Sub for this vid that was so class work but would advise buying a shop vac that filler dust was mental.

[@TofuAutoWorks]

I have a shop vac and I actually already half assed an adapter to go on the port on my DA but it was pretty garbage. Though looking back at this footage, might be worth another attempt.

Hi, just come across your channel. Great work 👏 do you have a video of you making the hardtop roof? I noticed when you taken it off the car it was thin fibreglass. Wanted to see it being made?

[@TofuAutoWorks]

The new roof I am building will be fiberglass and be pretty much the same. The original was a cheap replica that I bought for the car but it had a lot of small problems which is why I'm making my own.

[@MintMotorGarage]

@@TofuAutoWorks OK cool, I will keep an eye out for your next video as I want to make a light hardtop 👍

[@SpiderMax95]

I wonder what you will use for the rear window? I see you use the RX7 FD as inspiration, but that rear window would be too wide I guess?

[@TofuAutoWorks]

Normally a roof like this you would use Polycarbonate or Lexan but I'll be going a different route and fitting louvers with cutouts to see through.

[@cyberraptor93]

Please PLEASE get some extraction in that workshop, all that dust is not good for you! That being said though this is incredible work so far

[@HugEBear42]

I know its not the point, and this is turning out super well, but there is already fastback roofs you can buy for these mx-5's (miatas). it will be interesting how similar, if at all this ends up being...overall though, this car is fantastic!

a louvred rear and a small duckbill wing would like fire with that fast back
