I'm running bead locks but they are not Maximizes, they are Axial. I haven’t weighted them up, but I don’t think they are much heaver than stock wheels. They are holding up great (so far) and yes I’ve put them to the test on both my GR3 and G3 builds as well as my Duel V Twin 3905 E-Maxx. Here is the link to them..

I’ve got Proline Bow-Tie in the front and Crime fighters in the rear (40 series).
Hope that helps??
Have a great one..
