Our EU Series coilover system for the W207/C207 has been developed prioritizing ride comfort for those who are seeking to increase the vehicle's exterior aesthetics while still retaining a nice ride. By re-using the OEM front and rear top mounts, road noise is further insulated and kept away from the interior cabin. However with a slight increase of spring rates over stock and sport tuned shock valving, our kit is still more than capable enough for spirited driving or dare we even say track use. Megan Racing EU Series Suspension Systems are fully adjustable coilover systems which do not break the bank. With it's full length adjustable design, the vehicle's ride height can be adjusted without affecting the shock stroke ensuring a retained ride quality at nearly any height. Monotube internal shock construction separates the oil and hi pressured Nitrogen gas chamber preventing aeration. This allows for immediate shock response and damping consistency. 30-click damping force adjustability will also allow the user to fine tune the ride stiffness and response to his or her preference. NOTE: This system will delete the vehicle's "Electronic Damper System" if it is equipped and will cause a error notice on the dashboard. However no other systems will be affected.
