dsimonl I was VERY hesitant to go 18", fearing a decline in ride quality. I finally took the plunge and do NOT regret it. The car rides just a touch rougher and stiffer, but WOW the turns and handling are amazing.

I would recommend FACTORY 18" with no hesitation whatsoever. My 1991 has aftermarket 18" and I see a HUGE difference. Don't think you are smarter than AMG, go with the OEM.
