Hi, I'm back. I don't know if you remember that my 2013 black rt was rear ended and totaled. Well I just got a new 2014 SRT8 Charcoal grey w/black stripes. As you know there is no spare tire on the Srt, But I still want one. Can a use a regular 18in spare from a RT? I ask because the Brembo calipers are larger. Thanks
