04 Sedan - Rubbing with coupe 18s

Tirerack also has the section widths spec'd for each tire.
That 0.3" is a big difference when you have very aggressive offsets. It could mean the difference of rubbing and no rubbing.
Also, you can take some painter's tape and tape the fender, drive around, and look at where it is hitting the fender (on the tape). It could be just a wee bit of rubbing. If that is the case you could take a dremel wheel and cut off just a little (if you are comfortable in doing that).
Otherwise just roll the fender, drop the car, and call it a day.

BTW, your lack of a drop doesn't necesarily help you much since the stock susp compresses more. I say try to get a roll and then go from there. When it comes time for new tires, just do some research and be careful with the choices.

so are you saying that dropping my car with Z suspension could actually help? From what i read it also improves your ride quality and are not heavy on the pocket book so I might give this a try.
Should should I change shocks and springs? or will changing springs will suffice?

Droppng on the Z susp will not necessarily help. Rolling the fenders will.
I'm not sure I would say the Z susp improves the ride quality, but it did improve my handling greatly along with some other susp mods I did at the same time. I'm no expert, I did a lot of research here before moving forward, but from what I recall you should be able to do just springs (preferably revised) if your sedan has the sport susp. However if you have many miles on them you'd might be better off getting a whole new (lightly used) setup like I did. Not to mention I recall reading that the shock housings are a bit shorter on the Z reducing the chance of a clunking sound when they compress to their limits. Not sure how much of a problem that really is tho.

Thanks for all your input guys.
Problem solved - Went to a local shop and they actually used dremel to cut the inside of the fender. They did a great job and unless you are looking under the fender you can't tell anything was done to it.
According to the shop my problem was beefy tires (245/45/18s in the rear). He recommends i go with the 40 series in the future for better fit and looks on 18s.

Everyone with coupe 18s or 19s will have rubbing issues with stock tire size.
The reason most of the people are claiming they did not have issues is because
1. they did not notice it
2. they did not have 3 people in the back.
3. they were not cornering hard enough for the suspension to compresss enough
4. they have slightly more agressive camber in the back
Solution is to roll/shave the fenders.

Klubb, I have *never* been accused of being a granny driver so are you telling me I am just unaware of what is going on around me?

You can either:
1) Roll the fender in, very easy to do with a fender roller or some hand tools but with a lot of patience
2) Run lower profile tire like a 245/40/18 instead of 245/45/18 at the rear
3) Run more -ve camber .. but not good for tire life
4) Pretend nothing happens and call it a day
I personally run 255/35/19 on Coupe 19s in the rear and had to have my fender rolled in.

If the car was *loaded* down and I took a curve pretty hard it would rub slightly on occasion. The OP made it sound as if this was a constant problem in daily driving and I had nothing like that.

Then after him telling me that i confirmed that the tire had some wear on the outer lip of the tire because it was hitting the fender and making almost no noise. There a good possibility that most of the people never even noticed this happening.
