More out of curiosity than anything else. I live in the AWD market and was wanting to know which parts from the RWD would not be compatible with the AWD. As was the problem with the 3GS. Everything is factory made now though.

I run a staggered set up on my AWD, although my rolling diameters are almost equal. No problems so far in about 6k miles of driving

What tire sizes are you running?

225/40/19 front
255/35/19 back

so there like a 1/16 of an inch difference in diameters.

This is factory packaged F-Sport currently available for 2nd Gen IS, 1st Gen CT and upcoming 4th Gen GS, these packages are available in all world markets for Lexus. This is how Lexus will be branding their "Sport" model variants. Instead of loosely calling it a "Sport Package", its now officially an "F-Sport Package. Expect to see this expand into future Lexus models:




This is F-Sport Accessories are Lexus backed "aftermarket" accessory parts available for the current 2nd Gen IS, 3rd Gen GS, 2nd Gen LX by TRD USA. These parts are exported to Canada and Australia:

There is more to compensating for staggered wheels on an AWD model. Yes you can put staggered wheels on an AWD car. The reason why Lexus does not recommend it is because the safety systems (VDIM, VSC, TRAC, ABS) and gearing are calibrated specifically for non staggered tires. Because the AWD gearing is very precise, throwing the wheel rotation off by just a few rotations will damage the front and rear transaxles. The AWD setup is a lot more complicated than just throwing on parts and calling it a day. Subaru is a great example...it's not recommended by the factory to just replace one tire, the tire replacement should be replaced in pairs because its important for the front set or rear set of wheels to turn at the same rate, same goes for many AWD setups out there.
But they do have to have enough leeway front to rear to compensate for the fact that the tires could easily wear different front to rear by at least 1/8". That is not at all uncommon especially if you can't rotate the tires due to different sizes front to rear such as the new F-Sport has.

care to explain? if the diameters are the same I dont see how it can cause problems? General tolerances from tire to tire can be off as much as .06" anyhow, also tires that are more worn in the back than the front can be off by more than .06".
