I have the 4 wheel drive upgrade installed, and want to increase torque/reduce speed. I bought the stage 2 upgrade kit and there are gears to increase torque. I will have to replace the gears in both the front and the rear, right? Does this kit contain the gears to change both the front and rear? Any help would be great
For the evo models, all you need to do is change out the big gear on the side, the pinion (small) gear on the motor, the corrisponding (sp?) spacer, and use the metal heat sink. You don't need to mess with the AWD/4WD at all.
are you talking about the gears on the ends of the axles for the 4 wheel drive and the orange gears for the s2 if so you cannot use the s2 gears on the awd kit no point in trying
