Does anyone have this setup. 05 sedan sport w/18s. Id like to be as flush as possilble w/out rolling fenders. What brand and size spacer btw relatively inexpensive if possible

 

I recommend rolling the fenders if you want to get flush as the fender lip is worth about 10mm or more.

Without rolling you'll be able to get a 15 or 20mm MAX. and the 20mm would be pushing it.

With rolled fenders you could go 25 or even 30 in a squeeze.

Tell me where you're located and I can recommend a local roller for you.
