99 10AE turbo at 301 whp. Current brake setup is Sport front's with Hawk HP+ pads and DBA slotted rotors. Rear is non sport Hawk HPS pads and standard blank rotors. I also have the willwood proportioning valve and braided stainless lines. MC is OEM. Wheels are Jongbloed 15x8's (the "heavy" ones that sold for cheap when they came out a few years ago)
My front pads are just getting to the wear indicators and the rears are not too far behind. The same brake setup has been on the car for at least 40k miles, and before I installed the turbo it saw 3 track days and probably a dozen or so autocross events, and 3 autocross events post-turbo. The front rotors are a little warped and all 4 have pretty good wear and a ridge around the lip of the rotor. So basically it is time for a complete overhaul.
Some things I think about:
-Hawk HP+/S pads are very noisy and dirty, but do clean off the wheels easily. I have very minimal "permanent" wheel dust from these pads, but it's annoying to have dirty wheels after washing the car and taking a drive. They also work fine for hard daily driving and autocross, even at 300+ whp. I just don't know how they will fair on the track with this level of power.
-Keep stock size brakes but try a different brands of pads/rotors?
-Flyin' Miata is on backorder for just about everything. Don't really have time to wait for restock.
-I don't mind buying a kit second hand if someone has it for a decent price?
-I use the car semi-daily, try to do a couple auto cross events a year, and want to do at least 1 track day at my current power level. I don't mind spending some decent cash on doing this, but I don't think I need a $2,000 brake kit either.
-I see several other options from different vendors, but really don't know what would fit my needs and what would be overkill.
-I don't want to change wheels to fit some big kit. If a kit is too large, spacers will fix this?
-Is doing a big brake kit on the front's only and leaving the rear non-sport silly?
-If I do rear big brake calipers, I'd like to keep the parking brake, but not a deal-breaker.
HP+ is a compromise pad, it's not particularly good at anything. Try some better pads, G-Loc, Raybestos ST43 or whatever floats your boat, and some new rotors.

Ok, I'll start investigating those options. What are the go-to rotors right now?
One thing I don't like about the G-Loc GS-1, per g-locbrakes.com:
G-LOC™ GS-1
The G-LOC™ GS-1 is our high performance street compound. GS-1 produces very little dust and very little noise, while maintaining excellent initial bite and torque for street use. GS-1 has been unmatched in the industry for disc/rotor friendliness as well as its longevity. This compounds excellent performance on the street provides incredible braking force without ABS intervention. G-LOC™ GS-1 operating range starts at ambient up to 800°F (426°C). GS-1 is suitable for ALL street cars, tow vehicle, fleet vehicle, and armored vehicles. G-LOC™ GS-1 is NOT recommended for ANY track use.
I guess I'll just have to swap pads if I'm going to do a track day?
Consider PFC compound 11 front and rear. They are made in stock 1.8 NB fit. Extremely wide temperature range of consistent bite, and they release well.
I used them for a while on the street with good results save the amount of dust.

I've used the PFC pads for the past two years and I like them a lot. I've tried the EBC Yellows as my first non-stock pads, they didn't seem different than the stock pads. Then switched to the Carbotech's which had too much dust for my taste - corrosive dust, at that. Then on to the Hawks, which (as was said) were "ok" on the street and "not ok" on the track.
