HKS Hipermax IV SP Coilovers | 2009+ Nissan 370Z Z34 (80250-AN006)

As the Nissan 370Z (Fairlady Z Z34) heads into 10 years of production, many of the first models sold are being used more and more as dedicated race cars. Up to this point the Z34 has been seen to many as a weekend racecar that still needed to have street capabilities, but that's quickly changing.

In order to meet the growing race demand for the 370Z, HKS has released the SP-Series coilovers. These coilovers feature more aggressive track-mined dampening and spring rates. Even though the rear spring and damper still uses the OEM separate format, HKS redesigned the mounts for 65mm ID metric springs, allowing the track enthusiast to play around with spring rates if need be!

The HKS Hipermax IV SP coilovers are meant as coilovers designed for track and spirited street driving, if you are looking for something more comfortable on a daily basis you should consider the GT instead.
