yeah, the suspensions on these are adjustable to an extent. Unlike a real charger that has torsion springs up front, this uses a more basic coil-over shock design. I replaced the springs with stiffer units and replaced the shock oil with a thicker oil. This is mostly to offset the extra weight of the upgrades, and it's not perfect, but once I get some more jumps in I can see how it looks. I think a thicker fluid would help more, but no matter what I do the suspension is going to bottom, so it's probably not going to gain me much.
