I watched a video on YouTube of a serialnine dual caliper kit install on a gs300 idk the exact year of the car but looked incredibly easy and I was wondering if someone could tell me if gs300 Hubs are the same as gs400 hubs.

The video I saw was by David leidecker

Yes it's the same. Almost everything not related to powertrain or model-specific options is the same or interchangeable.

I just saw on the Serial Nine site that it literally tells you it works on the GS400. Come on, man.

Easy to bolt on some brackets for calipers, yes.. But the sourcing, mounting, and routing the rest of what doesn't come with the Serialnine kit is very difficult. The guy who's video you watched did a sloppy mock-up in a car that is completely ripped apart. No engine or transmission in the car, or diff/axles where he shows so easily routing the lines. No interior or center console where much of a hand brakes components need installed. He even installed his parts through factory parking brake locations that wont be vacant on your car. You will need to source a master cyl, a hand brake assembly, the braided steel lines to rout back to the lines Serialnine provides, and a multitude of special fittings etc to accomplish such a task. And also find your own way to mount these parts since he used oem locations for other parts. This looks like a very difficult and expensive task to me. Be warned.
