Does the Öhlins Road & Track DFV coilover kit fit all 2015–2018 Ford Mustang S550 models?

The Öhlins Road & Track DFV coilover kit fits the 2015–2018 Ford Mustang S550 and uses the original top mounts front and rear. It is not compatible with MagneRide-equipped models. Buyers with a MagneRide Mustang should confirm their vehicle's suspension configuration before ordering.

How does the single 25-click knob adjust the Öhlins DFV damper on the S550 Mustang?

Turning the Öhlins DFV adjustment knob clockwise firms up the damper into race mode by changing all four areas at once: low-speed compression, high-speed compression, low-speed rebound, and high-speed rebound. Turning it counterclockwise returns the suspension to a softer road setting. No tools are needed, and the adjustment takes seconds.

Is ride height adjustment independent from the damping setting on this Mustang kit?

Yes. Front ride height is set via the spring preload adjuster, and the rear uses a dedicated ride height adjuster alongside its spring preload adjuster, both completely separate from the damping knob. Changing the ride height does not alter your damping setting. Both axles offer approximately 5 to 35mm of lowering range.

What are the spring rates on the Öhlins Road & Track coilovers for the 2015–2018 S550 Mustang?

The front spring rate is 90 N/mm, using McPherson monotube upside-down strut construction. The rear spring rate is 140 N/mm, using aluminum monotube shock absorbers. The higher rear rate reflects the rear-weight bias of the S550's solid rear axle platform and the demands of hard acceleration and high-speed cornering.

Are the Öhlins S550 Mustang dampers rebuildable, and what warranty is included?

Yes. The Öhlins Road & Track dampers for the 2015–2018 Ford Mustang S550 are fully rebuildable, which also allows for custom revalving to suit more specific track setups. The kit carries a 2-year warranty and TÜV approval. All units are corrosion salt spray tested to ISO 9227.

Description

Öhlins DFV Road & Track Coilovers for S550 Ford Mustang

The Ford Mustang S550 (2015-2018) arrived from the factory as one of the most well-rounded performance cars in its price range, but drivers who take it to the track consistently find the same ceiling: a suspension tuned to satisfy a wide audience rather than push the chassis to what it’s actually capable of. The Öhlins Road & Track DFV coilover kit for the 2015-2018 Ford Mustang S550 changes that equation without turning the car into a punishment to drive to work on Monday.

How the DFV System Works

The Öhlins Dual Flow Valve (DFV) is what separates this kit from a conventional adjustable coilover. When the damper encounters a sharp or severe input; a mid-corner bump, curbing, or rough pavement at speed; the DFV opens a secondary oil bypass that allows the suspension to absorb the hit without unsettling the chassis. This lets engineers tune the damper for the firm, planted response the Mustang needs at the limit, while the bypass handles the inputs that would otherwise kick a stiffer setup out of shape. The result is a coilover that runs motorsport-spec spring rates and damper behavior while still responding sensibly to the everyday road surface.

Damping and Height Adjustment

A single 25-click knob handles all damping adjustment simultaneously across all four areas; low-speed compression, high-speed compression, low-speed rebound, and high-speed rebound. Turning it clockwise at the track sets the damper into race mode; turning it back before leaving puts the S550 back into a more relaxed road tune. No tools required, no separate circuits to dial in, no complicated setup between sessions.
Height is adjusted independently from damping on both axles. The front uses a spring preload adjuster to set ride height, with approximately 5 to 35mm of lowering range. The rear uses a separate ride height adjustment alongside its own spring preload adjuster, also with approximately 5 to 35mm of range. Ride height changes have no effect on the damping setting.

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.
