Point
A new ride suspension kit made specially for NISMO! Lowering the ride height brings your car more stylish! We refined more ride quality based on running quality analysis of the factory suspension.
Rear ride height adjuster Assy utilizes new design. Achieve both raising and lowering height.
If the vehicle height is low and the shock body length is shortened, it may interfere the vehicle body and ride height adjuster. We changed the ride height adjuster assy at the lower arm side can extend downward for preventing the interference between the body and ride height screw. Please be sure to read the instruction manual before adjustments.
We verify the steering response improvement and stiffer ride comfort with 7K spring load testing however, the product adopts 6K as a standard considering the balance of city riding occasions.
Please try stiffer spring rate when you enjoy the car just a sport driving or hobby use.
The default height set equivalent to standard vehicle height to compliant with the safety standard and considering the rear fog lamp height. Please adjust according to the test dimension and be aware of the rear fog light when you lower the vehicle. (Rear fog light height: 228 mm at the test)
Inner fender may interfere with the tire when full steer damping or the front shock body length set shorter than the test under the condition of the factory tire-wheel setting. Further, interference may occur between factory over fender and the tire under the condition of the shock body length at the rear side is shorter than 378 mm when full steer damping. In any case, there is no interfering with the upper and lower arm.
