there are only 3 ways to change Brake torque. rotor size, Hydrolic advantage, and pad compound.

changing the caliper would only change the pedal feel. on street driven cars we opt to keep the factory rear caliper to keep the parking brake. yes aluminum dissipates heat better, but the rear caliper on a v8 miata has a light load and we don't have issues with it overheating fluid.

i made this thread and cover a lot of brake topics and related.

 

Thanks for the link, Just trying to make informed decisions so I only buy parts once.

 

I've been doing a lot of research over the past few days weighing the options. And received some invaluable input from everyone.

Attached is an excel sheet that is my best guesses at the top options for us. They are in no particular order, and it looks like option 1 is no longer an option through our vendors. We would need to have a machine shop make the front Corrado Rotor Centering Rings and Caliper Brackets for Option 1.

I received this answer from Trackspeed:
"We discontinued our Corrado parts 5 years ago. The rotors have improper venting and are vastly inferior to a proper Wilwood rotor. The only BBK parts we have available today are our Gen2 11.75" Wilwood parts."

Please let me know if you find something listed for cheaper, as I want this to be a resource for someone that is as ignorant to brakes as I am.

 

what is with the ford explorer master cylinder?

 

Very cheap way to increase the piston bore with a bold on solution. Quite a few Miata brake upgrades running around with them.

 

yea but is it smaller/ larger?

 

Larger and how much depends on what you start with. My stock 96 Miata master was 7/8" bore and the newer sport brakes have a 15/16 pumper. What you see in the above photo is a master from a 96 Explorer. It is a 1 1/16 bore, bolts right up the Miata brake booster and was 32 bucks from Rock Auto.

 

Great info from Jim..... the ford explorer master is perfect for replacing non sport master cylinders. If you have the sport brakes with the 15/16 master cylinder and you need more from the master cylinder, then I would add the 1994 Mazda 929 master cylinder to the above list. Its a 1 inch bore and its plug and play... this is what I use. The later brake boosters need to have an o ring seal to the master.... hence the 929 master option.

Easy ☺
