Anyone have any brake questions?

Realistically the V8 roadsters 11.75" kit (F), add a joes racing floating rotor kit, PFC 299.20.0045.01/02 rotors, Flyin' miata brake bias adjuster, a rear sport rotor, na8 rear calipers, 949 na8 caliper-sport rotor adapter plate pfc 01 pads out front, and pfc 06 pads out back. combine that with some good tires and not too much caster you'll out brake a GT-R (fancy abs) from 150 mph-0

^ Interested to know this as well.
The Joe's Racing floating bit has me perplexed. I understand how PFC's full floating assembly looks, and am also familiar with semi-floating calipers on motorcycles, but how the Joe's Racing bit integrates with an existing wilwood hat/rotor setup isn't apparent to me...

right if you have excessive caster, when the nose dives your camber increases too. excessive caster can have an ill effect on braking. normally on our cars 3* of camber is good with 5* of caster. running 35% more caster then normal threw my tires into a excessive camber number. needless to say i need to calm that caster number down to 5-6*.

if you already have sport rears don't bother switching out, unless you want to run Padgid or PFC.

the Joes racing rotor flange is just an easy way to make a 8x7" bolt on rotor into a floating rotor. the track speed wilwood hats have recesses to clear the floaters and the v8 roadsters hats look like it won't be a problem.
The ring floaters will space the rotor back towards the chassis. if anything it will give you even more clearance as the rotor and caliper will be spaced rearward. this spacing will just about be perfect on the track speed kits as the rotor center line is a bit too close to outer hub bearing.

Ughh motorcycles. a colleague was working with yamaha racing team. he was working with them on a braking system. he had to stop when the team demanded stainless steel rotors. PFC doesn't make rotors from stainless steel because it has the braking properties of cheese. the factory team specked stainless steel because that's what the factory installed on production bikes. The reason factory uses stainless... it won't rust. the whole program was scrapped because of racing rotors that would last 2 events would rust, even though it was a huge performance advantage.

that might be an issue. i'm going to get a set of the joe's flanges and let everyone know how they fit.

still going to give it a shot. nothing else i'll get the hats milled down slightly to accept the flanges.

Not sure if this is a thing but what about a spacer between the hub and rotor hat that is the same thickness as the joes flange to space the friction ring back to its original intended location?
Would increase wheel offset a bit but not drastically..

i'm not a fan of spacing out hats. i would rather take it to a machine shop and give them 50 bucks to cut it.

i pick NA8 calipers for two reasons. 1) it keeps the parking brake, as requested. 2) pad selection is greater for the oem miata na6 & na8 calipers.this is compared to the sport rear calipers. it's not a strong caliper. In the rear the strength of the caliper isn't as important as the strength of the front caliper.
if you already have sport rears don't bother switching out, unless you want to run Padgid or PFC.

The two rear calipers (1.8 and Sport) cross fit the three brackets (1.6, 1.8, Sport)?
Choose caliper for piston size, choose bracket for pad size and space the bracket out to fit your desired rotor.
https://www.miataturbo.net/suspensio...51/#post779577 , Bob have fiddle a bit with these old brakes some time ago, and there have been few changes since then.

here's the link to joes web sight for the flanges. the track speed rotor uses a wide 5 8x7" bolt pattern. that's why the rotors are so cheap.

fairly normal procedure to modify pad backing plates.
