Ok, I have a 1999.5 1.8t with normal suspension and the 10" wheels LOL. I want to put 18" wheels on but I don't want it to be raised like a truck. People are telling me to get H&R race but Thats too low. I want it to be the height of an S4. What should I install? If I upgrade to audi sport suspension will that look good with 18"?

 

S-line suspension is basically what the S4 has, so going with that should drop your fenders down about an inch or so above the tires. The alternative is to get coilovers and set your ride height exactly where you want it, then leave it there or adjust height as desired. The pic of my car in my sig is with 18" wheels and OEM non-sport suspension, so that'll give you a little feel for how it looks. I now have S4 springs on my non-sport struts, but will be replacing the struts with s-line components in the near future, for exactly what you are looking for - the S4 stance. I don't want to go too low, but I'm not low enough yet.
