Installed these coilovers on my 370Z and the difference in handling and ride quality is significant .As a result of my tests, I determined that these coilovers provide a noticeable improvement in stability and cornering ability, while also lowering the car to give it a much more aggressive stance. The adjustability of the coilovers also allows for fine-tuning to suit personal preferences. The only downside is that installation can be a bit challenging for those without experience..
