The Rx7 brake pad had less surface area than the Dc2r surface area because it doesn't need it. During the number of pistons difference, if you know what I mean. Put in this way, I see a lot of Aftermarket upgrade 4,6,8 pistons calipers kit. I never see a Aftermarket Large single piston caliper upgrade kit. If you can find it, let me know. I don't think there are many.

Just like I pointed out earlier before, the Rx7 calipers was design for a heavier car plus the car had a turbo. I really don't see why the Rx7 setup going to be worst than the Ek9/Dc2r setup. Just common sense.
Have you ever driven a car on the track with a dc2r setup? And what rotor/pad combo are you thinking of running in the rx7 setup?

You do realise that more pistons in a caliper doesnt mean you're going to stop faster, it will give you more even pad distribution which may have a slight positive effect on braking, in saying that, you'll be running less pad surface area so you'll have less braking capability from that alone. The reason alot of oem parts are single sliding design is cost, its cheaper to make then a multi pot caliper.

You do realise that the dc2r uses the exact same caliper as a CRV, Prelude, Ek9, Odyssey, etc. Many of which weigh more then a dc2r. An nsx also uses the EXACT same pad as a dc2r and they also use a 282 rotor as well.
If you'd like to give me an explanation of how dc2r 282 setup running the same rotor and pad compounds as a rx7 setup is going to stop slower then a Rx7 setup, then please, i'm all ears, but logically if you have 282mm of rotor you're only going to have X amount of rotational force, if you want more get a larger rotor or better rotor/pad. You just seem like a typical blind fanboy imo.

Most important out of any of this is can your tyres hold up to the extra braking? (what tyres are you using?)
