so what is exactly needed to do this upgrade for an is250 awd? calipers off a 350 rwd will fit an is250 awd but rotors for the front will not fit the is250awd but will fit if you trim the dust shield? am i right? or missing something. thanks

...it's the wheel hubs. They're completly different. Because the hubs are different its now the cost of the hubs, plus the cost of knew steering knuckles plus the ancillary parts associated with the knuckle. Now, you'd be changing the entire suspension just to achieve a 4-piston caliper set-up.
We have not attempted as with the information above it not worth trying.

i didnt said that it will "bolt" right on. I asked if i trim the dust shield of the is250 awd will the rotors fit. However, he was talking about the calipers. So technically your telling me to read the wrong thing. Thanks though.

Jeff, would you be able to find out how much of the brake pads cover the rotors on a IS350 AWD?
I'm asking because when my mechanic installed the IS350 AWD rotors on my IS250 AWD and then fit IS350 RWD calipers over, he told me the brake pads aren't 100% covering the rotor. This didn't seem very safe to me so I didn't go through with the retrofit.
However, if you can confirm that the pads aren't used 100% on a IS350 AWD as well, then I might give it another shot.
Thanks!

Define not 100% used? Like a gap between the top and bottom of the pad and the rotor edge and center? How much didn't it cover?
I'm a bit confused.
EDIT: This should give you a bit of an idea how much of the rotor's surface is swept by the pad:
