  • Direct bolt-on installation for FC3S chassis
  • Reduces unwanted body roll and chassis distortion
  • Improves steering precision and suspension feedback
  • Durable powder-coated finish for long-lasting corrosion resistance

This front lower arm bar is designed to withstand the rigors of performance driving while maintaining a lightweight profile. It is a must-have for any RX-7 enthusiast looking to tighten up their chassis and improve overall driving dynamics.
