I found these in a local junkyard.

Big 4 pistons front and 2 pistons rear.

from a mercedes c230.

Is that possible to push them into miata's wheel?

I know not for 14 inches. But what about 15 or 16?

these calipers are just $11 every one.

for the mount, I have CNC in my lab so that should not be the problem.

 

just want to know if these front ones are in similar size with wilwood dynopro

 

and could please anybody tell me the thickness of wilwood rotor?

 

A quick word of advice before the regulars jump down your throat and disembowel you:

Search.

This question is easily answered by about 30 seconds of Googling. Nobody here is going to answer it for you.

 

then? I have two questions. what about the size of caliper?

I do not have dynopro in hands and cannot find one locally either.

 

it seems like I cannot use this set on miata.

this mercedes front caliper is designed for 13''*1.1'' rotor. On NA miata people use 11'' or 12'' rotor at the most of time. However, I could not find any 11'' or 12'' rotor has a 1.1'' width.

If I run this set on a 11''*0.81'' rotor, I possibly will push the pistons out of the caliper?

please correct me if I am wrong.

 

I guarantee you'll be the first person to put MB calipers on a Miata. Whip out your calipers and start buying test rotors.

 

by the time you've figured everything out and found a wheel that will clear the caliper you will have spent more than the $600 for the basic wilwood kit

For reference I have bastardized rx7 calipers over nissan altima rotors for my old evo3. Even though I got the calipers free, by the time i got spacers and extended studs and all the other supporting **** I would have been $150 off a proper wilwood kit

 

Lol at the words proper and wilwood in the same sentence.
I say do it, make it fit.

 

update：

I just came back from junkyard and got that calipers. I just bought the front ones because the rear wheels are stuck and I could not reach them....

still that question: can I use bigger caliper on smaller rotor? I could not find any information in Google world because people usually discusses about bigger rotor for smaller caliper.

the caliper is designed for diameter 13inch width 1.1inch rotor

can I put them on diameter 11inch width 0.81inch rotor? possibly diameter 12inch width 0.81inch?

 

relatively speaking?

pay no attention to the paint on the rotors



I am all for making due with what one has but when you live in the USA as far as the car world is concerned you have well....everything?

"You" guys don't rebuild ****, "you" replace it. My brother learned more from my failures and experience vs UTI and their Ford accelerated course. They taught him how to replace ****, not repair it.

 

gave it up

the minimum of rotor will be 12''-13''

not possible to run on miata with 11'' or less

 

this makes me want to murder.

 

Let’s take this from the top.
You want a junk yard merc caliper. Why? Better brakes? If you want to increase the performance of your brakes we’ll need to know the piston area, pad size, pad swept depth, rotor swept depth, pad thickness, compound, master cylinder size, balance of the car, spring rates, average operating temps. Then I’ll need to see what you have in the rear to take up the difference in compound coefficient of friction, rotor size, and hydraulic advantage.

99% of current big brake companies can’t figure this stuff out, and you want to give a go with an old set of rusty merc calipers. I applaud your initiative but I must warn you, to do it right you’re going to need much more than 500 bucks. I’m not sure you understand the amount of work it takes to build yourself a balanced system. If you can’t do the math yourself please look for help from a qualified expert.

 

but bro

they're just $11

 

....and they've got 4 pistons, which is twice as good as 2 pistons. So they're better, because numbers.

 

 

Don't let these pedestrian Miata-owning poors discourage you OP! They can't even imagine what precise, luxurious braking power those German calipers can deliver.

 

4 pistons for $11?!?!? I'm in.

 

**** those calipers. I want to know if I can put those rotors on my miata. Anyone know?
