I just purchased a 2012 IS250 AWD recently and thinking to upgrade to IS350 calipers front and rear.

I know i'll have to purchase front IS350 caliper, brake pads and rotors.
as for rear I'll need calipers and roters but I just noticed the brake pads parts # are same for IS250 and IS350. do they use SAME pads but just different calipers? if that's the case I can keep my pads correct?

I think the rear is identical btwn the 250/350 (caliper and pads) so there would be no reason for you to have to upgrade them. Just the fronts are different.

Someone please correct me if i'm wrong

rear rotors of is350 has vents which is250 does not, also, i know the calipers are different. now the questions is do they all share same brake pads.

yeah the front and rears on the 250 and 350 are different

i dont think they share the same pads either. i could be wrong but i dont think they do

I double checked few sites and compared part numbers and indeed they use same part numbers.
so basically IS250 and IS350 use SAME REAR brake pads.

That's right. Same rear pads, but rotors are vented,wider, and calipers are wider to accommodate the wider rotors. Is250s are a solid non-vented rotor.
