The HKS Z33 350Z Hipermax R Coilovers represent the epitome of suspension excellence. These coilovers are the result of meticulous engineering, incorporating the latest suspension theories and harnessing the wealth of knowledge cultivated by HKS over the years. The goal? To elevate your Nissan 350Z's ride quality and handling to extraordinary levels, surpassing what conventional dampers can achieve.
At HKS, we leave no detail unchecked. Rigorous testing at iconic tracks like Fuji Speedway has shaped the evolution of the Hipermax R series. Comprehensive evaluations, including the impact of bonded bracket bushings on the front and rear stabilizers, have been conducted. When adjusting ride height from stock conditions, the stabilizer's ability to absorb bush reaction forces is crucial. We've tested various stabilizer settings to ensure optimal performance, giving you the flexibility to fine-tune your suspension setup.
For our testing, we used the "S Special Package" model and even adopted a strut tower bar from the "NR-A" model for additional evaluation. Fuji Speedway provided the perfect backdrop for making adjustments to your preference, with five notches available for both front and rear tightening sides.
Front and rear retainers have been included to minimize rate changes during spring compression, ensuring a smoother and more controlled ride. However, please note that while our testing was conducted at a specific vehicle height, interference with the inner fender may occur depending on factors such as tire size, model, or suspension alignment. Be sure to consider these factors during installation.
Elevate your Nissan 350Z's suspension to a new level of performance with the HKS Z33 350Z Hipermax R Coilovers. Order now and experience the evolution of HKS engineering!
