The XRAY 303182-M rear lower suspension arm is a precision replacement for the X4 series. Manufactured with Carbon Fiber Fusion (CFF), this arm balances controlled flex and durability to help your car perform consistently on asphalt circuits.
The medium hardness construction is tuned for paved surfaces, delivering extra traction and steadier cornering. With the shock mounted in the middle of the arm, load distribution is evened out to improve mechanical grip and steering response.
Medium arms work well in hotter track conditions when additional traction is needed. They provide more compliance than hard arms, making the car more forgiving and simpler to tune for lap time gains.
