Please help identify this brake kit
 

I'm new to the forum as I've just taken over my dream car: an JDM Evo IX GSR.

The car is structurally decent but has seen a lot of owners and wear tear and I've started to replace and rebuild some key components of the car.

The car came with a custom engraved brake kit (a little obnoxious) and I'm trying to identify the Brand and model of the brakes so I can purchase the correct replacement rotors and be aware of what I actually own. From my limited experience I'm guessing that the front is a mini 6 pot and the rear is a 4 pot. I'm from Singapore, so it's likely that the brakes are an Asian brand (could be Japanese/Taiwanese). The closest looking kit I found is the Endless 6 pot front and 4 pot rear inch up kit: https://www.rhdjapan.com/endless-6-p...ct9a-cz4a.html

These are the measurements taken from the current rotors:
Front - 330mm x 30mm
Rear - 330mm x 24mm

Judging from the rotor wear, it looks like the rotors are the correct size for the calipers and pads.

If anyone could identify these brakes I would be eternally grateful.

If it turns out to be some off brand I've never heard of, I may even consider selling these off and reverting to the stock brembos as I intend to daily the car and don't intend to track it often.

Off hand question: will there be any fitment issues if I use a smaller rotor for the rear - say 320mm instead of a 330mm? What would be the consequences?
