I would try to run a brick pack as close to minimum weight as possible.
Ok, so I just went back and threw a light weight 2s LiPo in 3.0 and it fit. The plastic parts that stick down from the battery are just long enough to provide some support to keep the battery in place. Obviously, you'll still need to put a foam spacer on the the brace to help keep everything tight. I also weighed my car at 1508g. This is with the 1mm axle spacer and the 22-4 front inner hinge pins.
