Small update - For anyone doing JZA80 Supra brake conversion on a JZX100, specifically the rear: JZA80 inner brake shoes for JZX100 are needed, this allows the factory handbrake to work. I haven't installed the rear calipers and rotors purely because I didn't know these existed and I wanted to do some drifting and it would have sucked without a handbrake.
There are 2 companies that make the shoes - Kazama and Project Mu. I went with Project Mu conversion shoes.. I've had some varying feedback on how good they are but we will find out.
Visually - having both Supra front and rear rules.. it looks 1000x cooler. It also surprised me what a difference it made to braking.. the rear helps a lot and the car pulls up a lot more evenly rather than the front dipping down under a lot of hard braking.
The factory rear brakes are gross:
All new:
In other news, I managed to find a Power FC locally (new in box) for a really good price so I grabbed it, I also ordered a Tomei cast manfiold, tomei dump pipe and j-pipe delete kit.
And I changed the headlights.
