I don't now if these wheels I'm using for my car is legal or not, but I have a pair of Ofna black five spoke wheels 26mm (I think they're 2.0 too instead of the usual 1.9). I mounted sorex 20Rs (I race nights and the weather up here is usually pretty cold) 24mm and it fits like a grip...except..for the gap.
Just on the "looks" standpoint, these wheels to me add the aggressiveness to any of my car. To see it perform (it's a -3 offset wheels too) and constantly took a beating without major damage both on my electric car and my old stolen nitro car is awesome.
They usually sell these at a hobby shop for $8.95 for a set of 8.
well..that's my $0.02
