Building A Drag / Street Ve8 Buggy Need Advice !

You can use Jammin and Kyosho spurs with your HotBodies center diff, so you could use a 48T, 46T, or 44T. That's enough to squeeze out a bit of extra speed, and if you keep the 4.3:1 F/R diffs there still should be plenty of torque with a quality 4-pole motor on 6S.

Most options for increasing speed will reduce overall torque (higher rollout from either bigger tires or lower gear reduction, higher kv motor). The other main option is increase the voltage, but along with that come a few other things to consider.

I have a 44T Jammin spur that is too small for my gearing, like new, if you want to give it a try let me know.
