I was thinking 18's in the back and 17's in front. Would that look alright?
Suggestions for rims welcome. car is black

 

Not for racing just looks but i do have a need for speed every once in awhile.

 

16's or 17's all the way around IMO.

 

^^i agree..those two sizes are the best for our cars..

 

Are 18's too big?

 

?

 

The largest rim possible to fit on a 01-05 is a 20', even 18's are pushing it though.

I personally have 17's and I wouldn't want to go larger, especially if your lowered.

 

Get four wheels that are the same size. That will let you rotate the tires. And there are NO advantages to different-diameter wheels on your car.

You can get 17" wheels with 215/45-17 tires, or 18" wheels with 215/40-18 tires. You'll have a whole lot more choices of good tires in 215/45-17 than in 215/40-18. And the 18" rims will be a lot more susceptible to damage from potholes. So those are two reasons why 17" are better. Looks are a matter of personal taste, but I think 17" looks better too.
