The Fortune Auto Air Piston Lift System offers the convenience of a conventional air bag system without the loss in performance. The air piston slips on the shaft of the coilover assembly and extends the shaft to lift a lowered vehicle two inches.
Once the air piston is fully purged of its air, the cup simply acts as a metal spacer; no loss in performance or ride quality is experienced since the air piston has no moving parts when purged.
Fortune Auto 510 Series coilovers feature “Ultra” Double Digressive Piston (UDDP) with revised shim stacks, this “Ultra” Digressive piston allows for massive amounts low speed rebound force that helps with driver inputs such as dive, pitch and roll. Furthermore, the rebound force greatly tapers off to provide the driver with a supple and compliant ride while maintaining superior mechanical grip over rough surfaces. To put things into perspective the 500 series has a very respectable 3k rate swing of rebound adjustment. The 510 has an unheard of 8k. The additional cost is worth it if it’s within your budget, but both are great coilover sets. You end up with more digression, more adjustment range and an overall better coilover set. The additional cost is mainly down to more expensive pistons and more dyno time.
Coilovers are not a one size fits all part. To get the results you are looking for it is mission critical to choose specifications and options that are appropriate for your personal goals and priorities. Only a truly custom product like Fortune Auto allows you to do this. Sometimes choosing the right options can seem overwhelming, but Cygnus Performance, LLC has been helping customers with custom coilovers on a daily basis since 2006. We will be happy to spend all the time needed to help you with your coilover purchase. We will get you results that exceed your expectations the first time.
Like all Fortune Auto coilovers the 510’s feature one of the best warranties in the business as well as quick, inexpensive rebuilds in the USA. Not everyone thinks about these things when they are researching coilovers, but buying coilovers made by a manufacturer that does not offer good US based support can come back to haunt you. Fortune Auto’s support is second to none, so you can rest assured knowing that this is a product that you will only have to buy once. Cygnus Performance, LLC was one of Fortune Auto’s original dealers and now we are their master distributor. When you purchase through us you also get a lifetime of industry leading suspension tech support that will be here both before and after the sale and the quickest custom FA lead time available from any dealer!
Aluminum Damper Body Upgrade
Only available on double wishbone suspension applications. This would include the rear suspension of any 2008 plus Subaru as well as many other applications. This changes the material of the shock insert from steel to aluminum which has three major advantages. The first is it is lighter weight, the second is aluminum is very corrosion resistant and the third is aluminum does a better job of dissipating heat. The heat dissipation is particularly beneficial with double wishbone suspension since double wishbone coilover assemblies are typically shorter in length and therefore lower oil capacity. A worthwhile upgrade if it is within your budget.
Heim Joint Upgrade
Replaces standard lower mount bushings with spherical heim joint bearings. This removes all unwanted play between the shock assembly and lower control arm. If you track your car this upgrade will give you noticeably better handling. It’s difficult to articulate the difference you feel from the driver’s seat, but essentially you feel more connected to the car. When you are driving at the limit it will be a more confidence inspiring experience.
On some applications it is not possible to reach the rear damping adjustment without removing the back seat. Rebound extenders extend this rebound adjustment and allow you to more easily access it. On most typical sedan applications the extenders allow you to access the adjustment via the trunk.
Swift or Hyperco Spring Upgrade
Upgrading to one of these two brands has many advantages. Swift and Hyperco make some of the highest quality coilover springs in the world. They offer more accuracy than generic springs which essentially means they match the advertised rate and do not deviate much from that rate throughout the range of compression. More accuracy and consistency will give you significantly better handling. They also have less rate distortion which means the spring rate does not increase as much as the spring is compressed. This gives you considerably smoother ride quality. Hyperco is our preferred brand for a couple of reasons. They cycle the springs five separate times at the factory. This blocking process eliminates the sagging issue that most brands have. They also give you an industry leading plus minus 2% tolerance guarantee and lifetime warranty which is something that Swift does not do. Finally, Hyperco uses a separate coil wire diameter for every single rate which makes them the most accurate and the most consistent spring on the market. Both are excellent springs. You will be happy with whatever you choose, but people often ask us what our preference is. The answer is Hyperco. Hyperco is almost always the brand you will find on coilovers that cost more than $10k, and there is a reason for that.
Self Locking Lower Mount Collars
By default we include self-locking spring perches with every set free of charge. Upgrading the lower mount locking collar to self-locking will make things easier to adjust both during the initial installation and during any subsequent height adjustments. The standard locking rings require a hammer and a screwdriver for tightening. This is both less convenient than a cinch bolt and causes cosmetic damage to the lower mount locking ring. The self-locking version won’t slip, it will be easier to adjust if the threads are ever dirty and you won’t have to hammer away the finish every time you tighten them. This is not a must-have option, but it’s a worthwhile upgrade.
Remote Damper Controller
Also known as RDC this option gives you the ability to adjust all four dampers from the driver’s seat with the touch of a button. It features three separate user defined presets. This option can also be retrofitted in the future, so it’s a great option to be aware of whether you choose to add it to your initial coilover purchase or not. Being able to press a button and have all four shocks set to your preferred comfort, race or daily setup definitely beats getting out of the car and counting clicks. Very few of our competitors offer something similar.
There is no additional cost to customize spring rates, and unlike most other coilover brands Fortune Auto valves their shocks to match your desired spring rates. For most applications the Fortune Auto default rates are the most popular choice. Typically they do everything well. The default rates are soft enough that daily driving remains comfortable and stiff enough that the handling will be considerably better than stock with significantly less body roll. The default rates are also stiff enough to allow for a fairly aggressive drop in ride height. The default setup is a good compromise between all of these attributes, and it’s the most balanced setup. Coilovers are not a one size fits all product though, and that is why the custom rates are a no cost option.
Writing a spring rate technical article lengthy enough to address all possible scenarios is beyond the scope of this description. If you have specific questions that are not addressed here please feel free to send us a message. The president of our company, Geoff Parnum, who has nearly 20 years worth of custom coilover experience will personally help you determine the best possible rates for your goals and priorities. In short, if smooth ride quality for daily driving is a top priority you may want to consider softer spring rates than the default. How much softer to go is application dependent, but normally a 1k reduction in rate is sufficient. The downside of softening the rate is more body roll, but handling will still be considerably better than stock. If the best possible handling and minimal body roll are your top priorities you may want to consider going with a stiffer rate than the default. There are many factors involved in determining how much to increase rate for the best possible handling. The stiffer you go, the harsher the car will be on a bad road for daily driving. The final thing to consider is front to rear bias which affects the overall neutrality of the car and whether it is going to understeer or oversteer.
Choosing appropriate spring rates is absolutely mission critical to getting the results you are looking for with coilovers of any kind. Cygnus Performance takes the guesswork out of spring rates, and we even guarantee that you will be happy with our rate recommendation or we will sell you replacement springs at half cost anytime in the future. With just a few quick questions we will get you results that exceed your expectations. Don’t let a generic performance parts shop give you bad advice. Let Cygnus Performance, an industry leading suspension specialty shop, get you the results you’re looking for the first time.

Cygnus Performance purchases Fortune Auto coilovers 150 sets at a time in order to be able to offer you both quick lead times and custom colors. For aluminum parts we use exactly the same bright dip anodizer as Fortune themselves uses, and for steel parts we use the same high quality powder coat. Because Cygnus Performance uses the same quality finishes as standard color Fortune Auto coilovers Fortune Auto will fully warranty our custom color coilovers. There is no downside. You get the same great quality and support, and we don’t even charge extra for these custom colors. Our custom color options are just cosmetic, but they allow you to get coilovers that perfectly match your personal taste and build. The colors and finishes really are beautiful. Pictures don’t do our bright dip anodizing justice.
Radial Bearing Upgrade
Cygnus Performance includes a Koyo Japan radial bearing upgrade on all applicable applications for free (front McPherson strut applications). This radial bearing upper spring perch allows the shock insert and spring to rotate freely against the upper spring perch which both improves steering feel and eliminates spring bind popping noises.
Self-locking Lower Spring Perch
Cygnus Performance includes this upgrade both front and rear with every set. You no longer have to struggle with spanner wrenches and multiple collars. A simple allen head cinch bolt will quickly and easily lock preload in place.
