I'm really confused about what rotors fit the IS350 AWD model w/ F sport package. I seem to find 2 different sets of Lexus OEM part numbers, and the same for a bunch of aftermarket ones (Raybestos, Power Stop, etc.). Can somebody please confirm which of the following is the correct part number pairs for front left/front right rotors?

1. 43516-30040 (left) / 43512-30350 (right)
2. 43516-22010 (left) / 43512-22260 (right)

Based on my research, #1 is for the AWD models w/ or w/o F sport and #2 is for the RWD models. But when I asked lexuspartsdirect.ca they told me #2, even though I told them mine is AWD. What's the difference between the AWD and RWD rotors? I thought the only difference in rotor would have been w/ or w/o F sport package but that doesn't seem to be the case.

When looking at the aftermarket Power Stop or Raybestos models, they seem to have different models for C vs Base. So that gets even more confusing. If you don't believe me, just try to figure out what rotors to order from Rockauto.com lol

I have a Canadian model if that makes any difference.

These are the correct part numbers for a 350 that is AWD.

The C is the convertible model, that was a carryover from 2013...but it only came RWD.
The difference in the 350 front AWD and RWD rotors in the size/shape of the rotor hat.
F Sport or not doesn't matter for the rotors.

That's what I thought but lexuspartsdirect.ca told me differently. When I asked them again and sent them my VIN they confirmed that those are the correct part numbers. Thanks!

That's what I needed to know, thanks.
