| 43 | + |
| 44 | +- **Suspension System Modifications:** |
| 45 | + |
| 46 | + - Suspension beams are now drilled and secured to the rover body with long |
| 47 | + screws and torque-prevailing nuts instead of t-nuts. |
| 48 | + - Removed slotted holes from motor mounts. |
| 49 | + - Updated suspension beam fasteners. |
| 50 | + |
| 51 | +- **Wheel Enhancements:** |
| 52 | + |
