FPSpec Long-Stroke FPX CoilOver Kit (NA/NB Miata)

 We are proud to introduce our  FPX Long-Stroke Coilover Kit for the NA Miata and NB Miata Platform! The ultimate solution in customized suspension, specifically aimed at the Miata enthusiast.  A fantastic suspension option for those looking to maximize performance, ride quality, and price – our FPX Long-Stroke line of suspension offers great performance at a great value.

 You may notice that many components are similar / shared between our popular FPSpec line of products which utilize Ohlins DFV Dampers. This is not a coincidence. The years of R&D that went into our FPSpec Long-Stroke suspension kits was used as a starting point for our FPX Long-Stroke line. Utilizing many of those same hardware components, and reverse compatible with many of our FPSpec accessories, our new FPX suspension line offers amazing performance, and ride quality, at a competitive price point.  

 Hardware includes a custom-designed steel monotube shock body which allows us to reduce cost. We spec'd an industry-leading Nickel-chromium plating that is extremely durable in harsh environments. Matching gray 6061 Aircraft Grade Aluminum (mil-spec anodized in hard gray), and signature FPX Red springs (Swift Springs optional) compliment the entire shock package. High quality seals, shims, and pistons used throughout, as well as Amsoil shock oil, in conjunction with our proprietary custom valving.

We have built our FPX kits to utilize our "Long Stroke" damper length designs as standard, giving our FPX line of shocks an amazing advantage at a fantastic value.

 FPX Long-Stroke Spring Rates / Valving Options:

• FPX Long-Stroke Grand Touring (GT) Spec : A comfortable coilover for every day use, backroads, and (with a sway bar upgrade added) light track use.  VERY plush and comfortable for every day use and commutes when adjusted in the softer damping range, while very capable on backroads and for light track use when adjusted in the firmer damping range.
• FPX Long-Stroke Performance Street :  A well balanced mixed-use coilover setup, street oriented (for soft damping settings) yet track capable  (when adjusted to firmer damping settings).  A good balance between street and track use, with damping adjustment range for both scenarios.
