RE: Maximizer Beadlocks
My buddy ended up going with the Axial bead lockers. I don't remember which model, but those things were pretty heavy too. Instead of 8 screws per wheel, the Axial's have 16 screws per wheel.
Even though they were heavy, they actually helped performance in his Revo. He's running a .26 Picco and that thing has more than enough power to move! With the heavier wheels, he managed to gain distance in our local neighborhood jump by another 3 feet or so.
So as long as you have the power to move them, heavier bead lockers are just fine!
