I am building another Locost with Toyota 2JZ motor, and need to decide uprights and spindles soon. I am familiar with Wilwood brakes and I have a feeling that this car will need big ones. The owners of big brake kits, educate me with pro's and con's of the Miata package. The alternative uprights and spindles would be Mustang. s2000, corvette. But I know what to do geometry wise with Miata, availability is good, and I have basic spares. I would not mind having fifth bolt and beefier bearings, but so far it hasn't been a problem.
Road race is probably the hardest thing these brakes will have to endure, hillclimbs being shorter are easier on brakes.
If you are interested of the project check out

Thank you for your suggestions.

A member here has commissioned us to build him a BBK that hasn't been seen on a Miata yet. Depending on what wheel you want to use (15s depending on size/offset and most 16s), it may fit your project as well. I don't want to say much more in public, but PM/email me for details.

Didnt bundy determine that you could fit mini cooper brakes on the front of the car pretty easily that gives you the stiffer dynapros in 11.75 and 12.19 fitment in the front. In the rear anything off the shelf tops out at the same size as sport brakes, but someone does sell a 2 piece rotor for sport rear brakes that uses some 8 bolt pattern so maybe larger brakes can be an option there with different brackets.

whats the cross weight?
tire size?
compound?
Goal for horse power?
what kind of master cylinder are you planning on running, oe? - from what car? or Dual master cylinder pedal?

OGRacing,
The car is not done yet,
- based on driveline and existing experience gross weight will be 1700-1900 lbs in running condition.
- Tire size will dictate wheel size. I like to get used tires for local races. Formula Enterprise uses 13" x 10 hoosiers in the rear, and they are cheap and plentiful to run for a weekend, but I haven't found brakes which would fit inside those wheels. Next common slicks would be 15" and this may limit brakes too. Compound softest possible for short run hillclimbs.
-hp goal, 700 should be close from 2JZ single turbo.
-dual master assembly, cylinder diameter selection based on brake caliber needs.
The goal is to keep wear item costs down, tires, brake pads, balljoints, bearings and have available parts in the future.
Thanks

Well, racing brake does make a 2 piece rotor for the rear. I don't know about a larger rotor being possible. Any it depends on your opinion of racing brake which seems to be a mixed bag.
Someone needs to be completely dumb and create a carbon rotor that will fit under 15 inch wheels. unless maybe such a thing exists and I don't know about it?

I would choose suspension based on the merits of the design not available brake packages. The Miata double wishbone is gonna be tough to beat in a 1,700lbs car.
Even with a 700whp motor the current 11.75" offerings should satisfy your needs in a 1,700-1,900lb chassis. Who knows what Sav has up his sleeve. That could be the excess you're looking for.
Sounds like a fun project!

Thick discs will move rotor center outwards (steering knuckle in the way).
Unsure if their 21mm rotor would work up front.
Carbon discs are hard(er) to find info on, since most list them consulting items.
There are many smaller rotors in use on formula cars, but then we are talking different uprights, bearing packages etc.

I don't understand what problem you guys have with the Mini cooper kit I have been running since 2006.
Nobody yet has come out with an aftermarket production kit yet that is better for a High hp and heavy miata that easily fits in most commonly used 15" miata wheels.
Looks like V8R maybe finally coppied it by using dynapro radials however.
Dynalite calipers suck compared to the Dynapro Radials and you get 50% longer pad life via thicker pads.

V8R is currently using Dynapro lug mount calipers on their kits. Both V8R and one other company I know of are working on a Dynapro radial mount kit in 2015, but radial vs. lug isn't a significant difference.

nobody is really hitting on the point of how to slow a 1500lbs 500-800hp vehicle..
