I am sure that this has been discussed before and yes I did a search. My questions are slightly different than the others.

I realize that the front hubs are different and I would need to get ISF hubs to put these on my IS350. I was looking on Sewell and the hub assemblies for the 350 and the F have the same part numbers. Why is this? In addition, has anyone ever put ISF rear brakes on an IS350. What needs to be done to make this happen?

I really need help on this. This is not for some hypothetical scenario I have these front and rear for $500 bucks and need to get these on my IS350.

Bernie, I would ask Sewell about it... Because they do sell the ISF brakes for the ISX50.

Quick help question....replacing the front hubs with ISF in doing this swap - does that effectively change the ISx50 wheel offset to that of an ISF?!!?! Need to know ASAP. Thx

Yes and no. The wheels would now sit 5mm out from the knuckle, so in relation to the knuckle/suspension components it would now match the IS F, however the IS F has wider fenders, so the spacing to the fender would not be the same as the IS F.

old thread but since 2013, there's no need to use ISF front hubs. That's only needed if you're going to use ISF front rotors. Now you're able to use 2013 and up GS350 F-sport 356mm front rotors and bolt on the front ISF calipers to the 2nd gen IS. The rear ISF caliper and rotors already bolt up.
After you get the rotors, you can cross drill them to the ISF patterns so they match the ISF style on the rear.

Hey Phi, do we need to replace the dust shields too in the IS350 2nd? I'm thinking about GS-F conversion for my is350.

ELexis

I understand this to be an older post however, interested in installing as well and wanted to confirm Yamehoo's inquiry, if the OEM front brake dust shields need to be changed as well on the 2nd gen IS350 (Part 47782-22200 Left front) & (Part 47781-22200 Right front), to the IS F Brake dust shields (Part 47781-53050 Right front) & (Part 47782-53050 Left front) , when installing the OEM 2013 GS350 F-sport 356mm front rotors ( Part 43512-30351 & 43516-30041 ?) and brake pads ( Part 04465-30510 ?) then able to "bolt on" the front OEM IS F calipers without any modifications.(no need to use ISF front hubs to install the IS F calipers)..That's only needed if you're going to use ISF front rotors (Part 47730-0W030 x 2 ?).
The OEM IS F rear calipers (Part 47830-0W010 Right Pass rear & 47850-0W010 Left Driver rear) and rotors (Part 42431-0W030 x 2 ?) already bolt up"

I'm assuming all part numbers provided to be correct.

Are the GS 2013 and up GS350 F-sport rotors ( 4351253050 / 43516-53030 - front (43512-30351 / 43516-30041) same dimension as the the IS F rotors, but are "bolt on" with no modification when installed on 2nd gen. IS 350)?
