I'm running an B5m now and I had that same problem with it pushing I went with 3-hole 1.4 tapered Pistons taper sid down, kyosho springs gold in the front and white in the rear. I turned the rear camber mount to where the -2 is up then put 2mm washer under the ball stud. Then I have the aluminum rear hubs and put 3mm washers under that ball stud. Make sure the front axles are moved back and the rear hubs in the middle.
