Hey everyone, new member, but I have been following on G35driver since acquiring my '05 last year. I look forward to getting acquainted with everyone, but for now I'm looking into the diff gear. I've decided to build my G35 as a weekend warrior and I think a 4.11 would a great help in lowering my quarter mile time. Can't seem to find any info anywhere on where to contact about getting a 4.11 to fit the diff do if anyone can help me out it would be GREATLY appreciated!
