For starters: Wheels

Those pneumatics look kinda heavy to me, so maybe switch them out for 8" plaction wheels, or maybe even 6" ones. You should be able to get away with going over the bump with them.

If you're really pressed for weight, and want a competable robot, I'd put serious thought into not going over the bump at all. Take out the lift kits, and replace the pneumatic wheels with smaller, light ones. Re-organize your strategy to work on one side of the field. There are so many successful strategies using only one side of the field, and that could be a major benefit to you (PM me for examples of such strategies, we can talk).

That's a nice turret you have there. Take it off. A stationary shooter has worked extremely well for us, and from what we've seen at our practice day worked way better than the turreted ones.

Like said above, double, if not triple check your weight. You don't look heavy, but if you are, these are some steps to follow.
