No, you can't use the IS350 wheels. An AWD vehicle has the same size wheels and tires on all four wheels, and the 350's are assymetrical. Putting different size wheels on the AWD will mess it up big time. Don't do it.

How do you know that putting different size wheels (staggered) will mess up the AWD system? Can you please provide more explanation and facts on what the effects are.

1. if the rear tires are larger in diameter, they will turn more slowy in relation to the fronts. The cars traction control system may see this as the front wheels slipping as they are spinning at a faster rate. It may then (depending on the type of AWD) cut power, transfer power, engage the brakes, etc., (or any combination of the above) to compensate.
2. Mechanically: Some 'AWD' systems have locking differentials (basically turning the car into a 4WD vehicle.) All of the wheels will want to spin at the same rate. If the rears are spinning slower than the fronts, the fronts will be skidding a certain amount as they can't spin any faster.
Hope I've made sense. Keeping zero stagger is very important in AWD cars. Some manufacturers recommend replacing all four tires if one needs to be replaced.

Think about it. An AWD system drives all four wheels at the same time on even, dry pavement at some set ratio. When it detects one or more wheels rotating at a different speed due to slippage it will compensate for the wheel spin by reducing drive to that wheel and shifting drive to the other wheels. To make this work all wheels/tires have to be the same size, otherwise the system will detect that two of the wheels are always rotating at a different speed and will try to perpetually correct it. Mechanically this is not a good situation and will put increased wear on the system, and if it is out of line with the design limitations you are looking for an early mechanical failure. I suppose a system could be designed from scratch to use a staggered setup in AWD mode, but they aren't. AWD systems are designed for all four wheels/tires to be the same size.

This fine example is one of my very favorite Lamborghinis. The R8 with 277 hp. A fine machine by any standard.
