John,
Not sure about the 45 offset. Most of the guys here are using smaller wheels (17" or 16") and MT or Hoosiers for the DR setup. I have the 17x8 Voxx MG's and put MT P275/40R17 DR's. These are a 5 spoke and would look similar to your Nogaro's. The smaller combination should give you a little less rolling mass to deal with.

Another option would be to find a set of the light MB wheels for you DR's..... that is my next quest..
