Well, that is a wide open question, but let me try. There is 18x7,18x7.5,18x8, and I think 18x8.5 Hell maybe even 18x9. I have 18x7.5 with a +45 offset (very important when purchasing rims) Now, if you go with a wider rim such as 18x8 or higher I recommend you look into purchasing a rim with a higher offset like +48. Have you seen cars with the rims sticking out from under the fender? Well, that is due to improper offset.
Here is my 2 cents:
18x7 +42
18x7.5 +45
18x8 +48
Not sure what thr RS2's specs are.
Lets see what the other members have to say.
