Click & Collect . Semi active anti-roll bars. Anti-roll bars primarily influence suspension behaviour when driving over bumps in the road surface affecting only one side of the vehicle, as they transfer the forces to the other side. Anti-roll bars have a key role, as the are used to tune a car’s handling balance, bringing it closer to the understeer or oversteer zone. When the anti-roll bars are uncoupled, the axle can achieve an additional torsional twist of max. ARP system controls the wheel speed and quickly reduces the engine torque preventing your vehicle from rolling over. Weight: 4 kg: Dimensions: 35 × 25 × 25 cm: 1 in stock.
