Yeah I read through that whole build. He also had a lot of custom titanium parts made as well.

Ive just bought a punch and flare tool to do some experiment on non structural metal...

You are not mistaken, I just can’t read. They only have up through the 4000 series (single piece) for the rears. Shame, I was thinking they’d be a great way to shed weight without paying 2k+ for a bbk

well im working on my own lighter rear brake setup

Subaru 2pots calipers - someone advertised 3lbs lighter per side but once you ad in adapters it looks like ill be lucky to get a pound per side

Base model 11mm thin rotors - 2lbs lighter per side rotational

since there will be a gap of 8mm between the pads ive made spacers to push out the brake pads. I got 3.2mm spacers on both sides. So there should only be a 1.6mm gap.

This is all experimental until I install it next week but ive got all the pieces ready. If it doesn't work Ill just install the 2pots on the current stock rotors

SuperTom, the company called RacingBrake makes stockish sized two-piece rear rotors with an aluminum hat. They also put in an iron sleeve to allow functioning of the e-brake, so there isn't much weight loss. You might be able to do something with this, if your custom shims don't work out.

I like your attempts at lightening the rear brake setup, and I'm interested to see the results. Thanks.
