The overall diameter of your tires are way bigger than stock. The tires you recommended sound good, but those rear wheels are pretty agressive.

Do you have to run spacers in the front to avoid hitting the struts? Would you say your drop is similar to the drop with RSR down springs? I wanted to stick with 18" wheels to keep the ride quality with 35 sidewall rear. Even with 19" wheels you can't run any tires with sidewalls bigger than 30 in the rear.

The reason the rears are a little agressive is cuz i had these on a infiniti g37 coupe, i dont want to get new wheels. They were a little expensive.
Thanks I appreciate the help.

I recommend you go with RSR Half Down instead of RSR Down Springs. There was a member on CL that had RSR Down Springs with 20x10.5 in the rear and it damaged his fender. If you run 255/30R20 in the rear it will slightly prevent rubbing, but your tires will be super stretched so chances of you damaging your wheels is very high. That's why the biggest wheel for the 3IS is 19inch and no wider than 9.5 in the rear. Your wheels are nice though don't get me wrong, it's just they designed the 3IS a little smaller.
Here's what I would run for 20 inch wheels.
225/30R20 - Front
255/30R20 - Rear

I had a similar wheel setup as you, but ended up selling my 20in wheels and going with 18in Niche Misano instead. I was rubbing like crazy and the ride quality was a nightmare. You will also require fender work because 10.5 in the rear is too wide for the 3IS.

It will rub if you are making a turn as I mentioned it will be touching the knuckle if you do not add any spacers. Even when I added 5mm spacers, I do touch the knuckle when backing up and making a full turn so I am assuming 5mm spacers is still not enough, may you need 7-8mm at least

Damn, I wanted to run Enkei Nt03 18x9.5 +40 all around but don't like the idea of spacers.
Thanks for the info though.
