Manufacturer specifications
Our EZII Series Coilover Kit for the RZ34 will convert the rear suspension from a spring and shock separated system to a “true” coilover. This not only simplifies suspension adjustment but also allows the usability of our rear adjustable toe arms which will replace the factory spring bucket. Considering the spring is now mounted much closer to the wheel and has a greater effect on the set-up, a softer spring rate has been selected in order to compensate for the now lower “lever ratio” retaining the factory balance and comfort.
Now the choice is yours. Our EZII Series coilover system for the Z 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 using rubber 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 EZII 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. 15-click damping force adjustability will also allow the user to fine tune the ride stiffness and response to his or her preference.
