Non-US 86's have smaller non-vented rotors as the standard part, it looks like those come in about 1.5 lbs lighter per rotor.

Aluminum hat with a working e-brake does exist for other applications (bolt in and replaceable steel liner).
I could bug him and see if he's interested in this platform... |

Racing Brake might just have it
Paging @RB Performance Brakes
These guys might sell you just the rear rotors. They do offer a full kit here: https://www.racingbrake.com/ProductD...ductCode=2315K Rotor Design: These two-piece REAR rotors are made with the latest technology that is exclusive to RB. The rotor hats are constructed of aluminum with an iron sleeve insert. This allows significant weight savings, while still preserving the use of the stock emergency brake. This design is only available through RB! |

If taking that serious, then why need e-brake?
I was going to run custom rear brakes and dual caliper with hydro handbrake, but the drum hand brake is so good, do not need to change |

E-brake is required to pass inspection. Dual calipers likely adds more unsprung weight. Hydro handbrake is only used for drifting, it's NEVER a replacement for parking brake as locking the system like that for extended periods will damage components and isn't reliable enough. |

The transmission, rear diff and something called torque multiplication?
If the engine has about 50 ft-lbs of compression/friction at the crank, that's over 700ft-lbs at the wheels. That's a 15* slope, or roughly a 30% grade... That said, there are lots of times you'll want the engine running but the car to not go any where. Sitting in Grid, warming up the engine in the morning, in a drive through, etc. It's a PITA to not have an ebrake but an aluminum hat could easily handle these needs. |

Takes far less than that to rotate the engine, and the resistance isn't constant. If someone bumps the car and gets it over the hump of compression, the car will easily keep moving. Unlike using the parking brake which unless the cable breaks (unlikely) won't have this issue. It's also illegal damn near everywhere to park in this manner as well. |

You could always chock a wheel. I had to do that every time I got of my truck in the Air Force. I think there could be a decent market for the rb rotor setup in the rear. I wonder how much weight it would save though?
