Hello everyone!

Over the past few years I've developed various 3D prints for the A90 Supra chassis for a variety of different use cases. A majority of the prints have been exterior focused including fender vents, front spats, rear spats, headlight ducts, etc. All of these parts have either lived on my own A90 or friends (sometimes numerous friends' cars) and have survived for multiple years and numerous track events through a variety of weather! They've been on my website for a while but I've yet to formally introduce and explain them! If you find any of them interesting please don't hesitate to ask questions or provide feedback. Additionally, if you don't have a printer, don't fret, just send me a DM and I'd be more than happy to print whatever parts for you.

Time Attack Fender Vents

The fender vents were my answer to the current market offerings as a way to provide a cost effective and functional option. The current fender vents on the market are either incredibly expensive, take forever to produce, or are restrictive. While I won't say this vent option provides xyz lbs of downforce (because I have not wind tunnel tested nor used CFD), I will say these vents were designed with best aerodynamic best practices in mind as well as being customer friendly and extremely easy to install. Besides looking good, one of my favorite features of this design is the inclusion of a 3D printed cutting template as well as an installation guide (pictured below)

Using these guides makes the process of cutting and installing the vents an absolute breeze as you know EXACTLY where to cut, and EXACTLY where to place the vent due to the way the guides are formed to the hood. In other words, I designed it so that my idiot self wouldn't second guess all of my measurements and waste multiple days figuring out whether or not they are crooked....

Lower Vent Inserts

These inserts, or rather the lower circled one are a continuation of my front-end aero development efforts which shortly began after the time attack fender vents. I wanted to develop a lower venting solution that utilized the OEM fender and also did away with the windshield washer bottle. Reusing the OEM fender saves on costs and the fender itself really isn't that much heavier than any carbon (or rather 90% fiberglass) fenders on the market. Additionally, most of the current fenders on the market don't reach far enough into the wheel well. Rather than allow the wheel well to properly vent (and more importantly allow more throughput for splitter tunnels to work effectively) the current vented fenders see primarily wheel/tire wake. Currently, only the lower vent is finished but I intend on finishing the larger main vent this year!

Front Spats

Keeping with the theme of front-end aerodynamics, my front spats! These were specifically designed to work with the GT4 splitter/lip, however a handful of users have used these with other splitter/lip combinations. At the end of the day, if you can affix them to the bumper with 3M tape then you're good to go!

The purpose of front spats, sometimes called "tire spats" is to redirect air around the tire rather than allow incoming air to hit the tire head-on. This is mainly to reduce drag. I hope to create another design down the road as well.

Rear Spats

My first print for the A90! These rear spats are what catapulted me into designing more parts for the A90 chassis. Prior to these, my only other automotive work was partnering with Flyin' Miata for the NC/ND antenna delete! These rear spats have an interesting backstory as I found a 1/10 scale model to print. After printing, I had the idea that if this really was a "scale" model, then in theory these parts should fit the real, full-size vehicle. Well, I was 95% of the way there! All that needed to be done was develop proper mounting features and some very minor tweaks here and there. These rear spats pictured above have been on my A90 for >3 years at this point and have survived quite well despite numerous track events, road trips, and a few accidental parking scrapes.....oops.

Headlight Duct "Eyepatch"

My friend Kyle had been running a headlight duct for some time on his Gridlife Street class winning supra but was looking to iterate on that by adding a sort of "eyepatch". Essentially feeding the intake only the air it needs while not creating a large amount of drag with a much larger, unneeded pocket. After a scan and a few iterations, this two part design simply 3M tapes over the eventuri headlight duct and glues allows for the snorkel to be glued to the "eyepatch".

Similar to Kyle's headlight duct "eyepatch", Kyle was also looking at two different front spat packages to swap between depending on his current wheel and tire setup. The spat in red is for the wider/more aggressive setup whereas the yellow is for the more mild setup. Ensuring the entire front of the tire is covered when viewing straight on is important for proper drag reduction. However, the spats themselves do produce drag (albeit less than the tire does) thus using the right size spat for the correct tire setup is important for the most efficient drag reduction possible. These were developed using a scan of Kyle's car which utilizes a custom Verus splitter, endplates, and the A91 CF edition front lip.

I hope you appreciated the above portfolio of designs! I will be posting other designs that are not external/cosmetic related in their respective forums so keep an eye out! Thanks!

10/10 vendor. I have had his track fender vents for a long while and they held up GREAT. His included templates make this so easy a caveman can do it.


The vents also taught me I'm slightly dumber than a caveman, and to be better with my angle grinder.

Love the front tire spats. Still have to put them on with the racebred splitter that just got installed a few days ago, and figure out how it all fits together.

I also want the lower fender inserts, and will get to that at some point. They look nice on the EVS fenders.

I'm a bit of a carbon fiber fiend, so i wish i could have these in glossy CF, but that's just wishful thinking.

Ya know, a lot of them dont lol. I did a lot of these before actually creating an LLC, getting a logo, etc.

......I should get on that 🤔

Is there a material that holds up best to use? Thanks!
