Default Wheel sizing question.

So I apologize as I’m sure this has been asked but I have a 15 is350 f sport awd. I am planning on doing Rsr coils and looking for the right rim setup. I have a seibon kit on the car so I’m already lower and live in CT where roads are bad so I don’t want to go too low. Would a 19x8.5/9.5 32/38 setup work without rubbing and what size tires? Thanks again guys, still getting into this and don’t want to destroy anything including my tires? I was thinking 225/35/19 and 265/30/19 but don’t know if that will mess with anything being awd

I'm running 19x8.5+35(235/35/19) and 19x9.5+38(255/30/19) on a awd. I wouldn't go any lower offset on the rears as it just clears when airing out. Front I would've gone 30 if it was in stock. So you should be good with that set up as far as I know.

Will I need camber arms with this setup. Only going modest drop with the coils. I really don’t want to burn through tires

You'll be fine with the rim and tire specs you quoted above.
As for camber arms, really depends on what your final drop will be.
To give you a reference, with RSR Downs the camber specs are usually right on the borderline of the spec range...that would be the point where camber arms would be a consideration.

thanks for the input! Gonna start very modest and see what looks best but still gives me some clearance
