Hi Abarth22. I'm sorry for not answering earlier.

My rear calipers are from the Mazda RX7 FD3.

In my case, I did not replace the master cylinder and not install a rear brake regulator because I wanted to know to what extent would improve just changing brake discs / calipers / reinforced hoses.

Given that the front brake system I have also replaced, the improvement was equivalent. Very rarely I go to the maximum with the car, so that I'm content with the result.

To compare the performance numbers:

- Power OEM front brake system in brake tester: 3.2kN.

- Power of the new front brake system in brake tester (Brembo calipers Fiat Coupe 20V Turbo/ 305mm rotors, ventilated/reinforced hoses): 3.7kN.

- Power OEM rear brake system in brake tester: 1.2kN.

- Power of the new rear brake system in brake tester (Rear calipers of the Marza RX7 FD3/285mm rotors, ventilated (OEM rotors of the 155Q4)/reinforced hoses): 1.7kN.

Also I have to say, that new brake pads had 0km when I auditioned in brake tester, (I did not have time to do the shoot.) Now the braking has improved more, although I do not have numbers.

I'm gonna make a selection of photos.

If you need to know anything else feel free to ask.

Greetings.
