Singular Motorsports Fender Louvers for NA & NB
 

It's about time! These have been in the works and getting revisions for several years at this point. Used with lots of success on the HyperMiata in conjunction with a fender cut, but also tested with great results on an otherwise unmodified front fender.

Position is ideal in the highest pressure region of the wheel well, fins are optimized, overall shape is visually pleasing (IMO), I've got them dialed in. They pull a load of air out of the fender, reduce front end lift (more downforce) and improve the efficiency of brake cooling to boot. The only thing that was holding me back from releasing these much sooner was I really wanted to get one version hammered out that works in both NA and NB fenders. I've had them ready to go for the NA for a long time now, but the extra work of getting an NB fender under the knife and developing the template and shape further kept getting kicked down the list as a plethora of other projects and priorities kept getting thrown in. Finally this year, I got an NB in the shop for this purpose and after a few more revisions I've got it nailed for both generations.

Install is going to be a touch more work than the hood louvers, simply because you're dealing with more curvature in the fender than a relatively flat hood, but it's very doable. Like all our louvers, a vinyl cut template and dimensions are included to make the job straightforward. Obviously, you'll need to either trim or remove your plastic inner fender liner for these to be effective. I don't have a picture of a production sample to show yet as all the prototypes have been bare aluminum, but they'll come anodized black just like the hood louvers.

At this point, I'm just working out final production details and about to hit the green light to start making them. Aiming to have kits shipping around the end of the year.

Thinking about doing a group buy on the first batch of these, just like we did for the very first NA and NB hood louver kits years ago. MiataTurbo is where Singular Motorsports started, and I'd love to make it possible for you guys who are interested here to get your hands on these at a discount. Who's interested?

I'm in, assuming they don't interfere with the Left Lane Designs vents. Hard to tell from the pics.

I'm definitely interested but it looks like they might be larger than the allowable opening size in GLTC. Any idea how many square inches that is?

I'm interested. I got in on the original group buy for the hood louvers here too (got my limited edition pink Singular Motorsports decal). I have a separated question I'm going to PM you on about the hood louvers.

Interested for sure. I've asked about these both times I talked to you at COTA, so I feel like I have to get a set.

Also interested…these & hood lovers are on the winter projects list.

I think you're good to go. Looks like there's a couple inches between the upper corner of those and where these begin.

~75 sq in. so larger than GLTC allows by a good bit.
One could do a partial cover to choke the opening area down to the 45 sq in limit, and then the cover would be removable for non-restricted events...

I'm in.

I'm sad these are too big for GLTC bc they look sweet.

Also TIL GLTC has fender vent limits.

Im in, They look awesome!

I'm not against doing a GLTC version of these, which could be produced within the same first batch. It would be smaller (obviously), essentially a trimmed down version of the unrestricted full size fender louver. For the most effective use of that limited venting area allowed, you'd want to keep the forward most portion and trim the excess area off the rear. I just played with things a bit to see what works within 45 sq. in. and it would essentially be the forward 5 louvers. Still enough area to be quite effective and maximize the potential within that ruleset.

Here's a quick photoshop for what a GLTC version would look like:

Got back to a computer and upon taking a closer look, I agree. In.

I would definitely be in for a set of the GLTC versions if you decide to produce them.

If not I would likely still get the normal version and figure out some sort of block off plate though.

I'm fine with getting the vent as-is and then blocking off what I need to per rules. No need to customize for us dorks.

Got a cover plate drawn up that should do the trick. Because the NA and NB fender have slightly different curvature it would ship flat and you bend it to match the curve of your fender. Swap out the rivets on the rear 6 holes for M4 bolts/nuts and you've got a removable plate that brings the opening size of the vent down to GLTC requirements, or remove it for unrestricted days. Benefit of this approach is that anyone with the fender louvers can get the cover plate later if they decide down the road to run in that series.
I don't think we'd need to anodize these - just supply them in bare aluminum as you'd most likely want to paint them body color. Thoughts?

That's awesome, would definitely be in for vents/block off plate. If they were gonna be painted I'd just take em black so from a distance / in pictures it just looks like full size vent...bc the full size vent looks rad.

Nice looking parts! curious, do you have a photo of how they look on the NB you tested fitment on?

So far, just a bare aluminum prototype in a rough NB fender for development purposes. Keep in mind there were at least three revisions in this fender so it's not a perfect example of the finished version. But if you look past the junkyard finish and imagine a nice fender with black louvers, I think it's going to look just as good in an NB as an NA.

Groovy. Noted!

Noted and understood on the design iteration process. Looks nice! You can jot me down for a set on my NB as I'm re-evaluating some aero bits and always looking to continuously experiment.

Any idea how these would fit with (small) flares?

https://cimg7.ibsrv.net/gimg/www.mia...fc3194529b.jpg

I'm looking forward to installing these on an RX7. :P

Unfortunately the flare is going to interfere with the fender louvers. The only way I can think of to make them work together would be to notch the flare where it overlaps the fender louver opening, and you'd lose the top/center bolt on the flare. Doable, but some extra work involved.

Side note, on my car with 15x10s, I had a flare in the back but never found a need for a flare in the front. With the rear portion of the front fender separated from the rest of the front fender, you can pull the wheel arch wayyy out to clear a big wheel/tire combo.

That's what I was thinking too, looking at your images. This setup fit without flares, I'd just always wanted a flared Miata. :friday:

They look great, I’m in for the group but as well.

+1 for the GB, nice work!

Also interested in a GLTC pair, whether by cover plate or smaller vent, I am indifferent.

Just gonna leave this here as motivational inspiration for while I wait....

:naughty:

We're very close. Finished up the final details and costing for the vinyl templates at the end of last week. The last detail left is just concerning surface finish and coating. Samples of the louvers with a couple different finish methods went to anodizing yesterday, so I should have those back and a choice made soon.
SEMA is this week so I'll be consumed with that for a bit, but I think we can expect to be able to get group buy orders locked in some time next week, and everything is looking good for kits shipping well before the end of the year.

im in too........I'll do the PACO stiffening brace at the same time

An dennnnnnnnn?

Count me in. Would need a block off plate for gltc/nasa as well.

Whew! Got crazy busy last month so this took a little longer to put the final touches together, but THE GROUP BUY IS NOW OPEN.

Place your preorder on the website:
Singular Motorsports NA/NB Miata Fender Louvers **GROUP BUY** | Singular Motorsports

Getting in on the group buy gets you 20% off and discounted shipping. Aaaaand for Miataturbo.net folks ONLY I am bringing back the elusive, the mythical, the limited edition Singular Motorsports miataturbo edition decals in white/pink. For those who remember back to our very first group buy we ever did here, I cut these decals and included them with each GB order. It happened just that one time and never since... until now. So for just you guys here, when you place your order on the site include a note on the order during checkout that says "Miataturbo" and I'll include a decal with your order.

The group buy will run for two weeks or when we hit 30 units, whichever comes first. Giving you guys the first notice that it's up, and will announce it on the social medias in a day or two.
Production will start right after Christmas and kits should be shipping around the end of January.

WOOOT! Got my order in. But I forgot to include the “Miata turbo” part. Any way to still toss a sticker in there? 😅

Also orderd...and also same, ordered instead of reading the enitre post first :party:

ORDERED

Thank you for your orders!
I'm assuming all the orders that have come in so far have been Miataturbo folks since I've only announced it here, but so far nobody has remembered to add that note, so you're not alone :laugh:
I've added the sticker note to both of your orders. :party:

Ordered

Thanks, bud. My new livery has pink in it, so it's vitaly important to have a pink MiataTurbo sticker :giggle:

Nice, ordered. Grabbed the extra 2 hood vents as well, didn't know that was a thing. Between the fender vents from Padlock, the hood vents, and now these, I think the front end of my car will be more vents than sheet metal ;p Not sure it actually makes me any faster (at least with my driving) but at least it looks cool.

Order placed! Thank you for helping me out with the center and side hood vents a few weeks back as well. I lost my original pink decal as I had put it on a license plate frame years ago that is now gone. Looking forward to getting another!

They look awesome but NASA would nail me with 2023 TT points and really doubt they would be worth the point value and detune?

Hm. Didn't know this was a thing either. Ryan, do you have any data to back up the additional 2 louvers? I just want to see how much of an improvement they are over the standard 3pc kit.

Also, I will need the block off plates for NASA/GLTC, so im hoping those are done/included/will be out soon?

Ordered. Looking forward to cutting up more cars.

I would not do fender louvers at the expense of power.

The addition of the two outer louvers to make the full "Max Attack" 5pc set takes under-hood pressure reduction from ~50% with the standard 3pc kit to ~65-70%.

Working on partial blockoff plates to bring the fender louver opening area down to GLTC limits. Having a sample cut in the next batch of waterjet parts this month. Aiming to have those available at the same time as the first fender louver kits are shipping. Will be trying to keep the cost on those to a minimum so will likely supply them in bare aluminum and you guys can paint them black or paint/wrap them to match the body color.
Anyone who will need a NASA/GLTC cover and already has their order in, just shoot me an email in reply to your order receipt and I'll add a note on the order. Will let you know when I have more info on them after I've messed with the first sample.

Props added for customer service as it should be.

Just a couple days left on the group buy! Response has been overwhelmingly positive, decided to take more preorders than originally planned. Get in now if you want them.

Preorder sent. Amped!

Side note: Per your guys' recommendations, I'm gonna do a fender cut in conjunction with the vent installation. I see the Hypermiata has a pretty large/aggressive cut. Is it even worth considering a smaller cut like the popular one along the indented body line?

https://cimg9.ibsrv.net/gimg/www.mia...44af269c08.jpg

I had mine cut like that once upon a time. It only does a very small amount on its own. The high pressure turbulent air you want to pull out is up higher in the fender. In order of effectiveness, the ranking would be: 1) fender louver above the wheel, 2) BIG fender cut behind the wheel, 3) small fender cut behind the wheel.
If you were only going to do a fender cut behind the wheel, I'd push hard for doing the larger version - still not as effective as the louvers, but the larger version gets higher up in the fender and moves a larger volume of air out. BUT, since you're doing the most effective thing already with the fender louvers, the size of the fender cut is going to be less critical. The larger version will still draw more air out than the smaller one, but if you have a strong subjective preference for the smaller cut, go for it.

Sweet. Thanks for the detailed response.

I guess that's pretty close to what I was expecting. I'm gonna go ahead and do the big cut then. Not much extra to lose if I'm already gonna fillet the fenders anyway haha.

Thanks again. Amped to get my hands on the louvers.

Group buy is officially closed. Thank you to everyone who got in on it! Production is starting as soon as the waterjet guys are back in action after New Years.

Updates!

ETA
verything's going pretty smoothly, been making sure everything will be perfect with this first batch. We're updating to a different anodizing spec for better UV resistance on all louvers - this was due to happen sometime early this year, but I decided to push that forward and hustle to get it all set up with the new anodizer now because I want this first batch of fender louvers to have that new anodizing. It's taken some time to get set up with the new shop, which has pushed the ETA for completion of this batch back roughly 30 days. But I think it's worth the small delay rather than to do the first batch for you guys with the old anodizing and then update them shortly after that.

GLTC Covers
On the subject of those running GLTC, the prototype cover was cut and looks like it will work great. This will reduce the opening area down to 45 square inches as required by the GLTC rules, and the cover is removable for non-restricted events. The covers will ship flat since the curvature of an NA and NB fender are slightly different and you'll want to bend it accordingly.

Flat, as they'll be received:

https://photos.smugmug.com/Singular/...IMG_1697-L.jpg

I started by placing the cover on the fender and bending it over the curve of the fender to establish roughly where it needed to curve the most (I wasn't worried about the crappy paint on my sample fender, but use a rag or painter's tape to protect you paint on your own car). Took maybe 2 minutes. Then finished off fine tuning the curvature just by bending it by hand over my thigh, holding it up to the fender, and repeating. After about 5 minutes it matched up to the fender nicely.
Note 3 holes provided on the top, and you'll drill the 3 lower holes after you're done bending the cover. For those who get the GLTC cover, I'll include 6 nuts/bolts per side for use in those holes instead of rivets so that the covers can be installed/removed.

A few of the group buy orders have notes that they will be wanting these GLTC covers so I'll get with those folks directly to add this to their order. In the future, these will be available as an add-on option on the website when ordering the fender louvers.

I was kinda hoping they would also fade to the broze-ish color to match the hood vents LOL. Oh well.....

Thanks for updating the anodizing spec. Saves me from powder painting them.

Hard to argue with anodizing that actually stays black, but I was hoping for the same :p

Thanks for the update!

I need to get on here more often it seems! Sent an email from my GB purchase for the sticker/GLTC-NASA block offs.
