I'm aware of Tro-Nik, and I've exchanged multiple emails with them back and forth. I actually wanted to buy "something" from them, because of all the help and technical info they've given me.... but they just didn't have anything I needed.
There are a few rear brake options, but all of them require using a similar single-piston cast caliper. If the X5M had a sealed 4-piston, I would have bought the entire kit. It wasn't worth investing in a full BBK for the rear, for no other advantage than a rotor that is a few mm larger.
Currently, there is no sealed 4-piston BBK for the rear of our vehicles.. EXCEPT.... A full Rolls Royce Cullinan setup with Carbon brakes, and a dual-caliper setup (one small EPB caliper, and one larger sealed 4-piston caliper, per side.) As far as I know, Tro-Nik is the only people selling that as well.
I'm still waiting, and searching. Eventually someone will come out with a 4-piston rear BBK that works with the EPB on both the G05 and F95 platform. |
I know you keep saying they are 385mm, but they aren't!
G05 2NH M Sport brakes are 395x36mm - no current G series car uses a 385mm disc in conjunction with M Sport brakes. The sizes across the G series Brembo M Sport brakes are 348mm, 374mm & 395mm - model variant depending (G20 G30 G11 G05 etc).
