The solid rear lower suspension arms are compatible with the anti-roll bar system and feature two additional shock mounting holes to match the revised shock tower geometry. Molded from a hard composite mixture, the arms reduce flex for increased stability, improved response and more precise handling. They are particularly suitable for medium- to high-traction track conditions. The solid design provides high durability and a more direct handling feel while maintaining a balanced level of flex. Three different hardness options are available – medium, hard and graphite – to suit different track conditions.
