Nice brake pad carnage!

I know this setup is probably overkill for the majority of the driving I do, however - an insufficient braking system is one of the main reasons I have not been back to the track post-turbo...

You CAN put together OEM stuff that will work, but it will be compromised and eventually consumables will have paid for a BBK. Something is wrong with Thumpetto's setup. That's an anecdote i'd throw out in the context of this scenario. Not to mention that a street car on 15x7s probably isn't really the same sort of car we're talking about here. And i'd agree with him, a BBK isn't needed for a street car with 15x7s.

You can easily lock up the stickiest tires on earth with oem miata brakes.

Seriously, its not worth it (to me). They are just bling, and you could have spent that money on aero, or something else that may benefit you greater.

Especially since you dont seem to brake hard in the first place.
Sounds like you should have spent that $2k on several HPDE's with an instructor in the right seat instead

So you are complaining that your rotors are noisy, but also complaining that they aren't floating. You do realize that floating rotors make a ton of noise that you will hear at low speeds on the street, right?

Its just no one talks about certain parts and how noisy they are. I have mesophonia, and it was a large undertaking getting used to very expensive loud parts (squeaky xidas, and rattly brakes) The parts i added, like mazdacomp engine mounts, or delrin CA bushings, i knew about the nvh increases before hand.

im not saying the noise is bad, just trying to help another member that might appreciate all the details.

That's because when people need a BBK, they need a BBK. If noise comes with it, that's fine, because if you need a BBK, chances are you aren't building a Cadillac street car.

What happened to spending a few hundred bucks ducting the stock rotors before dropping a grand on a kit? Once big rotors get too hot, the rate they cool off will be dictated by airflow anyway. I'm sure the extra area helps, but I bet the airflow helps more. Are there any racing series that allow real pads and ducting but not bbks?

I would try ducted XP10/8 on centrics before going full bling.

One thing I discovered recently when looking to get the car trackable is that:
  • Big brakes require 15x10 wheels
  • Big wheels require body work and narrow springs
  • Narrow springs means might as well upgrade to Xidas
  • Might as well duct brakes first since that has no dependencies

Yeah, I don't buy the argument that you have to have the biggest wheels and tires and the biggest brakes and the biggest spring package and the biggest turbo setup to be trackable. I think incremental improvements in any of the components are the way that most of us proceeded. We didn't jump right into a 350 plus horsepower car with massive brakes and massive slicks and 1000 lb Springs. That's how Race shops build race cars but that's not necessary to build a trackable dual duty car. I started off on used street tires on 15x6.5 and then graduated to used SM6 and DIY bilsteins. I did a lot of track days and had a good time learning. I wasn't trying to win anything. I just wanted to have fun. As I used stickier tires and went faster I needed more brakes.

Nonsense.

Every Miata needs 15x12's, xidas, kswap, efr9180, and 14" 10pot carbon brakes.

That's just to get started daily driving

I find it interesting that you're a contrarian for most everything that folks talk about here, especially re:949/TSE (and v8r?). That said, I sympathize with your mesophonia, but all the research I did on miatas before even buying one led me to believe that the cars just about always have some sort of rattle or noise and that they weren't quiet cars by any stretch of the imagination. I think that no one talks about this stuff because the expectation is that racecar parts don't usually meet anyone's definition of 'quiet'.
