Here's the situation. I have a 1990 NA with stock brakes that i use for track days and autocross. I am planning on putting a turbo kit on in the next year or so and am wondering how much power the stock brakes can handle. I don't really want to get a BBK for a few reasons. 1. i don't have the money 2. the wheels that i have for the track (Enkei RPF1) won't clear BBK.

So what can i do to get the most stopping power and least brake fade out of the stock brakes?

Cheers
Marty

94+ brakes. Need rotors, pads and the brackets for both front/rear. It'll increase the rotor/pad size and it reuses the stock calipers.

Good fluid and pads will also go a long way in this setup.

I have a 91 with stainless brake lines, cross drilled and slotted rotors, and thermoquiet pads. My car stops extremely well. I plan on getting some street hawk pads or some EBC pads though and I should be able to stop on a dime.

at 170rwhp w/slotted rotors, redstuff pads, ate super blue fluid, stainless lines. I had major break fade and boiled my fluid after my 2nd session on the track.

Seriously consider a 1.8 upgrade if you start boosting and autoxing/tracking

size comparison can be seen here:

NAPA blanks are typically Brembos and have been proven time and time again that they handle abuse fine $15-20 each. No point spending money in rotors. It's all about pads. I have Hawk HP+ on order for the street and will be using Blues on the track. Should prove much better results. Ducting in air wouldn't be a bad idea as well.

Someone correct me if I'm wrong... but you should be able too. You just need the caliper bracket for the front and rear (swap the brackets from L to R up front) and then rotors/pads.

You are basically spacing the 90-93 caliper out farther, using a larger rotor and larger pad. With fresh fluid... you have a nice "new" brake system.

how about my abs?

The ABS sensors are on the hub...I don't think that there are any sensors on the calipers themselves.

Keep in mind that 01+ cars have even bigger brakes. The calipers from them WILL NOT fit under stock 14" Miata wheels, however.

 

[Splitime]

ABS sensors are typically not located on the brake rotor/caliper/bracket.

Unless I'm sorely mistaken. Typically they are mounted on the spindle and the trigger ring is attached to the hub or axle end.

 

[Braineack]

yeah, you can go bigger with NB brakes. You must replace all components. calipers, brackets, rotors, pads. but it should still work. will not 14" rims most likely.

abs shouldn't matter one bit.

cool! thanks guys!

 

[TRoadster]

Thanks for all the info guys. So what is the smallest wheel i can use with the 1.8 brakes? and what do the costs usually run to convert to 1.8?

 

[Driftdevil]

as long as you use NA 1.8 brakes and not the sport ones the factory wheels will fit

Rota RB 13x8 +4 offsets clear 1.8 brakes - BARELY.

I spent:
$50 on the brackets
$72 on the rotors (Brembo Blanks)
$88 on the HP+ Pads
-----
$210

Will sell my Powerslot Rotors and new HPS pads for cheap to offset the cost.
