All New for the Nissan 300zx Z31 Coilovers line are the following upgrade of anti-corrosive zinc coated shock/dampers and PPI (Polymer Plastic Injected) Damper Dust boost for further longevity.

The Z31 R/T Coilovers feature a robust grade inverted mono tube strut piston. Which is valved for the serious competitor and features aluminum pillow ball upper mounts to transfer more suspension energy through the strut piston shaft increasing the efficiency of the overall suspension duty.

Full forged steel threaded shock bodies for independent ride height, spring preload adjustability and liner springs make the RT Coilover System an “All Business” tool for Auto crossing and Road Racing.

For best results, we recommend upgrading to the Swift Springs.

SWIFT spring composition is manufactured using their own proprietary steel alloy “HS5.TW”. This material was formulated in order to maintain the 4 major performance factors listed below, as well as achieving the fastest reaction speed possible to get compliance on road surface conditions.

“SWIFT springs are created with proprietary winding methods, as well as some other trade secrets focused on ensuring the their product separates them from the standard market.”

 The 4 Factors that separate Swift from the rest of the spring industry: 

  1. Consistent spring rate throughout the stroke = more consistent performance
  2. The largest amount of stroke to maximize suspension motion.
  3. The highest durability against loss of spring height = excellent material memory prevents springs sag over.
  4. Extremely light weight to reduce sprung weight increasing over all agility.
