SL55/63/65/R230 AMG: 20" Auto Couture Insignia's on my 06 SL55?
put it this way ......the stock wheels are the best if u want pure proformance out of this car . 20z will make it feel like somethings holding it back abit . After getting used to it ... it will feel just as powerful again .
goodluck and enjoy the mod
If you go with performance forged wheels like HRE, you'll be better off then stock.
