The DragRace Concepts Team Associated DR10 Anti Roll Bar "ARB" System is a must have upgrade for the DR10. The "ARB" system is a drop in option that requires no modifications. The design ties the rear suspension together, allowing the rear arms to work as a single unit rather than independently, helping to increase traction and stability under power compared to an independent suspension set up. Additionally, the rear shock tower alters the shock geometry, placing the shocks in a more vertical position to improve rear weight transfer at launch.Â
