You can see it clearly how the Rotor are 2 pieces and the caliper has different shape than the standard GS/IS350 caliper.

i know theoretically, the 4th gen GS350 RWD calipers and rotors should fit 09-13 RWD IS250, i just wish someone bit the bullet and got the whole swap and confirmed it fit without any modifications (besides trimming dustshield)

The 2 piece F sport rotors are a few pounds lighter (small difference) but the F sport calipers weight a ton.
We have a front and rear kit, 6 piston front, 4 piston rear, all for about $2000, and it will outperform any F sport setup. We used Forged Wilwood 6 piston Aero 6 calipers up front, and Forged Wilwood Superlite 4 piston calipers out back. Pad replacement cost is also significantly less than OEM sized F-sport pads. We also do custom colors.

^Researching picking up a used 2IS in the next few months. I assume your kit work with the OEM 2pc GS F-sport rotors. If so, would you sell just the calipers and mounts?

I would need to get dimensions off of the F-sport rotors in order to see if the offset was compatible. I need to know the thickness of the mounting bell, and the offset from the mounting bell to the outside brake surface.
That said, I don't think those rotors are worth the expense. They are certainly not lite weight @ about 22+lbs, so the weight savings is only 3-4lbs. Our calipers are much lighter than F-sport calipers (I will weigh the f-sports soon).
As a complete package you get our front 6 piston 14" BBK and rear 4 piston 13.6" BBK, all for about $2000, and we do custom colors to match.

Heads up. with these stock 13+ GS350 f-sport 2pc rotors, you can slap on 08-14 IS-F 6 pot brembo calipers to the front and they will bolt up and line up perfectly fine. no mods in hub/shims/spacer needed.
reason. 2006+ IS 350 front knuckles and the 2014+ GS 350 F-sport knuckles are the same PN. therefore, the same 2pc rotor and is-f brembo will also bolt up on the 2nd gen IS on the front without hub/shims/spacer.

I thought ISF had different hubs. I am 100% sure everyone that did an ISF BBK conversion on their 2IS had to change the hub bearing assembly, which leads me to believe the spacing and offsets are different.
