[N14] Upgrade rear brakes

[WalknBullzEye]

Just did a brake upgrade on the front. Made brackets and installed 200SX 4-pots calipers with 300mm discs (11.8"). Now I'm looking for a big brake upgrade for the rear also. Can't use 200SX 2-pots caliper, because of the Pulsar's handbrake mechanism. All depends on the calipers cylinder(s). The bigger, the better.

Is there anyone who tried this and could give me some advise please?

Front setup:

There is a 5mm spacer mounted, otherwise my wheels wouldn't fit. That's why you don't see the stud holes, but original they are 5x ... and bored to 4x100. The discs are Brembo RS9597 (300x47.0x26.0), original for the Renault Laguna (2005-2007).

S13 rear calipers are very similar to the N14's, or aren't they?
