What does "progressive rate" mean for these springs?

A progressive spring's rate isn't fixed; it stays softer under light load for everyday comfort, then firms up as load increases under hard cornering or track driving. That's different from a linear spring, which applies the same rate throughout its travel regardless of how hard the car is being pushed.

How much does this lower the car?

Approximately 20mm at both the front and rear, which lowers the car's center of gravity and reduces body roll without the extreme drop of a dedicated track-only spring.

What are the spring rates?

5.5kgf/mm at the front and 5.0kgf/mm at the rear, roughly 10% stiffer than the stock FL5 setup. Spoon Sports paired that increase with more rebound stroke and a redesigned coil geometry to keep street compliance rather than making the car harsh.

Why did Spoon Sports develop this instead of a standard lowering spring?

Testing on the stock Civic Type R showed high roll rigidity but a slight delay in roll initiation on track, which made it harder to trace the intended cornering line on corner entry, and the stock ride felt too stiff for everyday street driving. This spring set was developed specifically to fix both issues at once rather than trading one for the other.

How does the barrel-shaped coil design improve ride comfort?

Spoon Sports increased the coil count and spring length, and used an irregular-pitched, barrel-shaped cross-section to lower the load needed to get the spring moving. That makes the ride more compliant over small road irregularities at low load, while the progressive rate still firms up for higher speed and spirited driving.

How many springs come in the set?

Four: two front and two rear, enough for a complete spring change on one car. There's no need to order twice.

Description

Spoon Sports Progressive Spring Set for FL5 Honda Civic Type R

The Spoon Sports Progressive Spring Set for the FL5 Honda Civic Type R is designed to enhance both handling and ride comfort, offering a refined driving experience without sacrificing performance. These springs feature a progressive rate design, meaning they provide a softer, more comfortable ride during normal driving conditions, while firming up under load for improved stability and cornering performance. Engineered with precision, the Spoon Sports springs lower the car’s center of gravity, reducing body roll and improving overall handling dynamics. Perfect for street or track use, this spring set optimizes the performance of the FL5 Civic Type R while maintaining everyday drivability.

Testing

To fully understand the potential of the world’s fastest front-wheel-drive sports car, Spoon Sports tested the stock Civic Type R on race tracks, winding roads, and city streets across Japan. It was immediately evident that the stock suspension setup featured high roll rigidity. However, on the track, the slight delay in roll initiation prevented the driver from smoothly tracing the intended cornering line during entry. Additionally, the ride felt too stiff for comfortable street driving. Spoon Sports set a clear goal: to develop progressive springs that would enhance performance driving at all stages, allowing the driver to follow the ideal cornering line while providing comfort on regular streets.
To enhance sports driving performance, Spoon Sports increased the spring rate by 10% compared to the stock setup. Additionally, more rebound stroke was secured to improve compliance over road irregularities. These springs lower the car by approximately 20mm, resulting in a lower center of gravity for improved handling.

Development

Spoon Sports’ development team also focused on improving ride comfort. By increasing the number of coils and extending the spring length, they reduced the load required to initiate the spring’s response. The response rate was finely tuned with the use of an irregular-pitched spring featuring a barrel-shaped cross-section profile. This design improvement lowers the load needed to activate the spring, enhancing street ride comfort, while the progressive spring rate maintains traction for higher speeds and spirited driving.

For over 40 years, a deep admiration for Honda sports cars has driven the company’s progress, leading to the development of groundbreaking tuning parts such as the carbon hood, monocoque aluminum opposed atypical calipers, and throttle bodies. This philosophy, or “Spoon-ism,” is what gave birth to the brand, Spoon Sports. It is the brand that transforms revolutionary ideas and philosophies into tangible, high-performance products.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
