Mitsubishi Evo VI Makinen Brakes for FD
Hi Guys! I am trying to find some information on the EVO brakes to fit my FD. i have searched but i didn;t find alot of help. Are these are direct fit on the FD rx7? I have access to a pair of front Brembo brakes and master cylinder off an EVO VI Makinen Edition. I am very inclined to get them but i have no idea of what are the implications. Can anyone help please? Thanks! Ken

The first thing you need to do is spec these brakes. Figure out the piston diameters and the size of the OE rotor it was used with. Then there is a formula to calculate brake torque to determine if this is actually an upgrade. Sometimes it is very surprising results!
I calculated the brake torque for the RX7's OE 4 piston calipers and compared it to what came on my VW Golf because I was considering using an extra set of brakes I had laying around as an upgrade. As it turns out, the RX7 brakes have 25% less powerful clamping force even before calculating in how small the rotors are. They probably are a lot more efficient of course because they are 4 piston vs 1 big piston, so they might actually work, but I just said forget it when I compared them to some other calipers. The Porsche Cayenne brakes are a %100 upgrade in brake torque wile only increasing the rotor diameter by a little over a centimeter. So without gaining much rotating mass, I make an enormous jump in brake power. Combine it with a 2-piece rotor and it's actually lighter than the OE brakes! The only problem is they require more fluid so a larger master cylinder is recommended.
As far as if they are direct bolt on, I'm not sure. I tried to search the Brembo caliper schematics but it's showing the same caliper for the RX7 and the Evo. So I'm not sure what that means.
