Default Brake Upgrade

Any advise on low $ brake upgrades for 90 Miata. Not wanting to invest $1K plus at this point.

Your lowest cost upgrade would be a swap to the larger 1994-97 (NA02) brakes. You'll need:
-1994 Front Calipers and hangers (new or used)
-1994 Front rotors (buy new, best price currently is Summit)
-1994 Front Pads (don't scrimp, buy good ones)
-1994 Rear Hangers only (used is your best bet. I have a bunch lying around if you want a set)
-A 1994 rear brake hardware pack (the caliper is the same but the hardware is different)
-1994 Rear rotors (again, Summit's the best price right now)
-1994 Rear pads (matched to the front is best)

Using used parts where possible you can do the above for under $300 or so. The next step would be a set of brakes from a 2004 MazdaSpeed Miata (also known as "sport brakes"). You'd need the same parts as above in addition to a set of rear calipers as well (the sport rears have a larger piston). You could do that for under $500 or so. The next step after that would be to try to incorporate a 1991 VW Corrado rotor on the front using a set of R-Speed hangers. The rotors cost no more than Miata rotors and the special hangers cost about $130 IIRC. The next step after that would be to move to a Wilwood 4-pot caliper on the front which is really not that expensive (only $125 a piece from Summit). You can use the kit from TrackSpeed to mount them over the Corrado rotors or you can go right to Wilwood and get their whole front kit that includes a two-peice front rotor. I think that kit sells for right about $600 which is really a pretty good price.

I currently have a set of Wilwood 4-pots mounted over 1991 Corrado rotors in the front of my car using the hangers from Trackspeed. On the rear I'm using the original 1994 brakes. I only have about $500 in this set-up as it sits and it actually did pretty good on the track. On the street, however, I feel it's a little over biased to the front. To try to remedy this I'm upgrading the rears to the 2004 Sport rotors via the R-speed kit (about $120). I'm also upgrading the Master cylinder and booster to larger 1994 Mazda 929 parts but that's more for "feel" than "effect" and probably would not be happening if I did not use the car for the track. When done I'll still be under $1000 spent including the larger booster and master.

My vote would be for the 1994 stuff if you only use the car on the street, and the larger 4-pot front, sport rears if you track.

Your car looks awesome BTW. Welcome to the forum,
