try the .075 fiberglass T bar with the center screw out.put 5000 wt 1/8th scale diff oil on the king pins and also 7000 wt diff oil on the washers.run your rear tires at 1.800 and your fronts at 1.700 and use the double pink front jaco wraps with yellow rear wraps.i like the wraps better than the high rollers and standard tires.run 3.5mm ride height front and rear.this should help alot.no rear damping sounds like what is making your car push.
