Supermiata BX1175 Boxmount BBK
 

Announcing the new Supermiata BX1175 Boxmount BBK. Taking pre-orders in a week or two. Later we'll release our separate 3" duct and hose kits. The orange duct you see in this image is a proto (and no it won't fit your brakes, sorry). Production duct will change a little.
Base kit with BP20 pads and straight vane rotors. Upgrades to G-loc pads and directional rotors. Visit the website for current pricing.

Confirmed fit wheel list:
15x10 +25 949 Racing 6UL
15x10 +25 Konig Dekagram
15x10 +25 Jongbloed Series 500
15x9 +35 Konig Dekagram
15x9 +35 Sparco FF1
15x8 +28 Advan TC4

Because the OEM spindles are lug mounts, we discovered it's overall stiffer to use our double shear boxmount and a lug mount caliper than a cantilevered radial adapter bolted to the spindle ears in single shear. Like our BX11 kit,
the small form factor our our bracket allows a full 3" port directed at the hub underneath the caliper. The lower image is a view down into the backside of the rotor. We also closed up any holes or gaps in the dust shield and hat to force all that air through the vanes and caliper.
On a separate note, we're stoked to have moved all wheel and parts engineering and design in house. That CAD render is 100% in house. Either drawn or for OEM parts, based on a photometric scan to a parasolid. All FEA and fatigue testing, in house.

Superlite 4 piston lug mount calipers
Patented Supermiata Boxmount caliper brackets
G-Loc or Wilwood 7420 (20mm) pads
11x7.5" x 1.1" directional or straight vane rotors
6061 T-6 forged CNC hats
Braided brake hoses

Duct kit will include the duct you see in the pic, proprietary backing plates and all mounting hardware but no hoses. That should come later, maybe October and run somewhere around $200/set
Hose kit will include flange for the nose, hoses, clamps a few other bits and run around $70. That'll also be October or thereabouts.
Offering the duct & hose kits separately for those that need to configure things differently for their build
Combine BX1175, duct and hose kit will give you everything you need to put full time attack brakes adequate for a 500whp car.

Oh yeah, in case you hadn't heard, we have some new wheels coming ;)

Yay!!! :party:

As soon as you open the pre-order I'm in.

Looks mega. The lack of previous kits offering something wider than 0.81” baffled me.

That's solely because there is a single 11.75x.81 Wilwood rotor that retails for like $35. It's a piece of crap but everyone used it for the last 15 years because it was cheap. We would have our own, much heavier wall directionals made but even those were limited. TSE's kit used the .81 but had the 20mm thick pads which was nice. We ran those on our cars. Still not enough rotor though. Our new 1.1" directionals are much thicker wall than the cheapie 11.75x.81 Wilwoods. While the weight may scare some away, I have learned to love thermal mass when it comes to brakes.

Maybe I missed it in here and on the site, but how much are replacement rotors and are they custom made for you guys?

Spare rotors product pages not built yet. Custom, US made. About $250/pair for straight vane, around $310/pair for directional vane.

These rotors are substantially thicker wall than any other NA/NB BBK on the market. Add the 3" ducts when they become available and both pad and rotor life will be better than anything else available.

Will 15x9 6UL with a 5mm spacer fit? I'd imagine this isn't what you'd call huge!? But just wanted to check.

You said the forthcoming ducts won't fit my brakes, but will they fit your BX11 kits or is that a separate design?

I forget exactly but I think t was more like 10 or 15mm. Basically a no go.

Our duct bolts to our bracket and flows through a gap that no other bracket has. BX11 will have a different duct. Same basic style and still 3" though.

Do you have a stock 16 incher for a test fit?

yes please

Awesome! Thanks.

I don't think so, sorry. You will have to download the template once we upload it to the site.

Can we get a picture of all your ducts in a row?

Joke aside, we'll publish full images of the ducts when we start taking orders for them. Some details we want to keep under wraps until then.

BX1175 Wheel Clearance Template

Some additional wheel fitment info added to the product page.

Expected day these are going on sale? Didn't see a button to add them to my cart yet.

As of today, we think we can ship the first kits around the 2nd week of September. Like everything else, we're waiting on various suppliers.

Yeah, supply chains are a disaster right now. Christmas is going to be a mess this year.

Yup.

Hell ya just ordered.

How much more do these weigh per wheel than your box mount 11's with light weight rotors?

Haven't made that comparison but the BX1175 are going to be significantly heavier than the BX11. Caliper is about twice the size and the rotor has about 40% more thermal mass. When designing the BX1175, weight was not much of a consideration.

Curious though, why do you ask?

Truly a massive pair. Orders in.

I just ordered your BX11's and lightweight rotors for an Exocet. 300whp with an LFX on E85. Car weighs right around 1700 lbs and has Xidas, RB swaybar up front and AR1's in 275 width all around. Weight is a big factor for me on this car. Curious if you think I should be running the 11's or 11.75's. I have the FM little big brake kit on the car currently with the Wilwood rears (has a parking brake) and was planning on keeping the rears. I'm fine paying more to upgrade, was just thinking it would be nice to save some weight if possible.

The BX11 will stop that just fine, but you'll be going through pads with that kind of power and grip on track. Sounds like you have room for the BX1175, and the huge pads will last much longer.

BX1175 for that build.

LukeG,

Better to directly contact Ed for recommendations than rely on me through a forum.

Thanks Guys. I'm upgrading the order to the big uns. Cheers!

BX1175 wheel clearance
 

We just updated the template on our site. It's a vector file so those of you with 3D printers and the ability to draw in CAD can turn it into a physical part. We'll be uploading an STL file so folks can print a part without needing to draw anything. We'll also have a loaner wheel clearance tool that we can ship out.

https://supermiata.com/supermiata/Su...l_Template.pdf

We're updating the confirmed wheel list as we can get our hands on other brands of 15x9 and 15x9.5. Visit our website for the latest wheel clearance info.

Is there a wheel list, or only the template at this point? I have hunted through the pages a few times, and don't see a list of wheels that have been checked for clearance.

Only confirmed wheel is the 15x10 6UL. We'll add wheels as we can get them here to test.

The template is accurate. If you have a printer (paper) and a pair of scissors, you can check your wheel.

Great news, @The Australian , the 15x9 Dekagram fits with no spacers needed.

We are gathering more wheels to test fit for those that don't want to use the brake template.

Ed

Since the 15x9 Dekagram fits without a spacer, we expect this to clear ALL long-spoke design Advanti and Konig (Storm S1 & S2, Helix, Dial In) and Jongbloeds too. Might even clear those same wheels in the 15x8 +25 - we think it will. 15x9 Countergram and Hexaform, maybe.

EDIT: Since this post, we tested a 15x9 Storm S1 and it will require 8mm of spacer to clear. I won't keep updating this, so check the product page for the most up-to-date list.

If someone has one of those wheels they want to let us test fit, shoot us an email at info@949racing.com.

Christmas come early :)

For those that want to check brake clearance with their wheels and might be intimidated by the need to print the template and check that way, we're offering an alternate solution with a simple fit tool. You can order a physical 3D printed buck in the shape of the brake to put in your wheel for fit check. Send it back and we refund the cost of the tool. You can also use the template on the product page to create your own tool if you have a 3D printer at home.

Uploaded an stl to Thingiverse for people that want to 3D print their own template but are not keen on designing.

If this is an issue in terms of IP please let me know and I will remove it.

Not a problem and thanks. We'll link to it on our site.

Added to confirmed fitments without spacers. No surprises with these two but its nice to confirm.

15x11 Jongbloed Series 500
15x10 +25 Konig Dekagram

Just tried 11.75 template with new 9" wheels from Phil's offering and it fits without spacers - the Joengbloods 15x9 hits the lip and needs a 5mm spacer (already confirmed)

https://planet-miata.com/ke-motorsports-pro-wheels/

while these wheels clear - the balancing weights if placed towards the inside lip will be an issue. likely 5mm spacer needed.

Fitment notes added to list. Thanks!
You need at least 3 mm clearance to any part of the brake.

Duct ETA?
 

How far away is the date when an order can include the ducts?

No ETA on ducts yet. Still tweaking the design. Hose kit will be available soon.

I figured ~8 months is a reasonable amount of time to ask if you have any updates on the duct/hose kits?

You would think that, and you'd be right, but still no ETA. Final (hopefully) prototypes should be arriving very soon, and if they check out then we go to production.

It's taken us a few tries to get the ducts fitting the way we wanted. It's proven to be quite a challenge. As with most things these days, longer lead times to get prototypes and production started so it's taking more time than we had hoped. Thanks for your patience everyone.

I have the patience of a saint and love to support you guys, so I will continue to patiently wait! Thanks for the update.

Patiently waiting as well, but you can't rush perfection!

Ducks!
 

Quick update: Brake duct design is finalized. Production started though the lead time is a bit long. We should have them in stock early March.
Working on a short video to show the ducts up close. Should be uploaded in a week or so.
