You're pretty limited with options. There's the D-Max fibreglass rear quarters, I think they do them up to 50mm wider. You can couple those with either matching front wings, or GTR ones.
There's also the BN Sports kit, although that's not so much widebody as Wiiiiiiiiiiiiiiiiiidebody. It looks fat, swollen and bloated, I find.
Another option would be to graft in the rear quarters cut from a GTR shell and stick GTR front wings on.
