In 2018 we revolutionized Datsun S30Z suspension upgrades with our Techno Toy Tuning Evolved Coilovers—the first fully bolt-on coilover kit available for the 240Z, 260Z, and 280Z. Designed and fabricated in California, these coilovers use mild-steel housings with chromoly spindles, premium internal components, and shock valving tuned to your specific driving style. With over 25 years of Z-car experience, we confidently deliver the best Z-coilover solution available under $10,000.
We offer two strut casing configurations for your S30 coilover upgrade:
-
OEM-Modified Strut Casings – A cost-effective option using original 240Z/260Z/280Z housings. Send in your cores or request a set from our inventory.
-
All-New Evolved Casings – Brand-new, precision-engineered casings for maximum strength and long-term performance.
To fine-tune alignment, choose from our Solid Pillow Mounts, Bolt-In Camber Plates, or Weld-In Camber Plates. Our coilovers can also be adapted for use with OEM rubber mounts.
Every system includes Koni Sport Short-Stroke Shocks and HyperCo Springs for exceptional ride quality and predictable handling. We also offer Swift Springs for a JDM-focused setup and HyperCo Helper Springs for aggressive track or lowered applications.
Standard Sport spring rates begin at 200 lb/in front and 250 lb/in rear, with 50-lb increments available to match your street, canyon, autocross, or track goals.
All Coilovers are built to order; lead times vary.
