The Ksport Circuit Pro 3-Way Coilover Kit offers extensive customization for your vehicle's suspension system. Built to order, these coilovers allow you to fine-tune your setup. You can choose from rubber, pillowball, or Ksport's advanced pillowball upper mounts, which provide integrated camber and caster adjustment capabilities. Each kit includes Ksport's 55mm Monotube shocks with remote reservoirs, ensuring robust performance. To guarantee optimal setup, every system is individually dyno tested. The results of these tests can be provided upon request at the time of purchase to assist with coilover tuning. This kit is specifically designed for the Mercedes-Benz C-Class models from 2008 to 2014. Please note that production and delivery typically take 2-3 weeks as these kits are built to order.
