Was thinking about this today.
Why don't manufacturers use twinpot brakes on the front like Brembos on the back of an Evo or STI or like on the rear of an Altezza?
My thoughts is something to do with either cost or brake pad surface area?

You want to know why manufacturers use sliding/floating calipers (pistons on the same side) over fixed (opposing pistons) calipers?
The main answer is because sliding calipers are cheap and easy to manufacture and wheel selection is better because they can fit behind a wider range of wheel offsets. Evo/STI Brembos are fixed calipers both front and rear not just on the rear.

They need to be cast in two seperate pieces, machined perfectly flat on the mating surfaces, then assembled before they can be fitted.
Slider types require a lot less machining.
The 4 pot brakes like the nissan or brembo ones, in my opinion the main advantage over sliding twin pots is that you dont need to fart around removing the caliper to swap the pads, they can come straight out the top.
