On the front of the block, there is actually a counter bore so the shoulder of the screw can go into the caster block some for wheel clearance, etc.



There is nothing designed in to change the height of the battery strap. Ultimately, you want to run the highest capacity battery as you can at minimum weight, since a larger capacity battery will improve your voltage throughout a run. Since the 3.0 is pretty light, it should be VERY easy to get under minimum with a standard size shorty pack, and if I was going to race stock... I would try to run a brick pack as close to minimum weight as possible.



I really like the Orion motors, I don't think you can get better although they do cost a little more. I'd probably get a 7.5T myself.
