I have a 2011 lexus is350 awd model, I am planning on buying coilovers for it and lowering it. I don't think lowering it can hurt my drivetrain in anyway, correct me if I am wrong. Now my main question is in regards of my tire and wheel setup. What route can I go to avoid any potential problem to my awd system. I'm assuming I would need to run a squared setup, not staggered. But can I have wheels that are the same size but different offset without potential damage? Example would I be about to run a setup like 18x9.0 +36 and 18x10 +38 without issues? Sorry if this is a commonly asked question or if I'm not making sense, would appreciate any opinions. My main concern is the awd system.

Thanks,
Tony

Offset doesn't matter, what matters with AWD is the same tire diameter on all 4 wheels. You could use staggered wheels and tires but make sure overall diameter stays very close, otherwise it could potentially drive the computer nuts. Usually an AWD systems likes to see similar diameter tolerences.

So I would be able to run 18x8 and 18x9 as long as I run the same size tires is what you're saying correct?

 

AWD lowering past 24.5 inches ground to fender = increased chance of tearing cv axle boots and eventual cv axle replacement.
