Do the Sport S Coilovers for FK8 also fit the FL5?

Yes. Cusco USA lists part number 3C4 64S CN for both the FK8 and the FL5 Civic Type R. The two generations share the suspension layout this kit bolts to, so the same Sport S Coilovers for FK8 and FL5 cars fit either car with the same springs and mounts.

Are these coilovers comfortable enough for daily driving?

They are the softer of the two Cusco Sport kits for this car. The 8 kg/mm springs and 24-step dampers are tuned for street radials, and the dampers can be set soft for commuting. Pillowball front mounts do pass a little more road noise into the cabin.

What is the difference between the Sport S and the Sport R?

Both kits share the monotube dampers, 24-step adjusters and pillowball front mounts. The Sport S runs 8 kg/mm springs front and rear for UTQG 200 to 350 street tires. The Sport R steps up to 14 kg/mm front and 16 kg/mm rear for UTQG 100 to 200 track tires.

Will the drive modes still change the suspension?

No. The Cusco dampers replace the factory adaptive units, and the supplied cancellers take the place of their electronic valves, so the drive mode selector no longer alters damping. The 24-step adjusters set it by hand instead, and the setting stays where it was left.

Can I take the car to a track day on this kit?

Yes. Cusco rates the Sport S for street driving through HPDE use on UTQG 200 to 350 tires, so a road-driven Type R on 200 treadwear tires is what the kit was designed for. Drivers who move to 100 treadwear tires and run regular sessions will get more from the Sport R.

Description

Cusco Sport S Coilovers for FK8 / FL5 Honda Civic Type R

Cusco’s Sport S Coilovers for FK8 / FL5 Honda Civic Type R are built for the tires most Type R owners drive on: street radials rated UTQG 200 to 350. The kit shares its monotube dampers, 24-step adjusters and pillowball front mounts with Cusco’s track-focused Sport R, but runs 8 kg/mm springs front and rear, so the car sits lower and rolls less without a track-car ride. Choose it for a Type R driven on the road and taken to the odd HPDE day; a car on track tires suits the Sport R.

Design and Performance

Each damper is a monotube design, with oil and gas kept apart by a floating piston so it stays consistent as it heats up. The case is threaded for its full length, so height is set at the lower mount without changing spring preload or stroke. Pillowball front mounts let camber be set for even tire wear on a lowered road car, the use the Sport S Coilovers for FK8 and FL5 cars were built for.

24-step damping through Cusco’s patented needle valve

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.
