New Corvette Coilovers

Following in the footsteps of the recent launch of our premier Double Adjustable coilover the Feather Light Generation DAs, we are announcing the little brother with many of the same features: The Feather Light Generation SAs (Single Adjustable).

The Feather Light Generation SA coilovers are a completely new design for the Pfadt family of Corvette suspension. Most notably, this product separates itself from the competition in the following ways:

INVERTED DESIGN: Placing the majority of the mass on the sprung side of the chassis allows the control arms and outboard components to react quicker and easier without the additional weight of the coilover itself. The result is a suspension system that responds faster to changes in the road whether its highway, local roads, or track surfaces. The less weight that is on that outboard suspension, the better your car will behave – you’ll have a better connection between your Corvette chassis and the ground. Make sure your next set of coilovers are inverted.

LIGHTWEIGHT, HIGH STRENGTH MATERIALS: Gone are the days when coilovers need to be made of corrosive steel components. The Feather Light Generation SAs are an all aircraft aluminum body which boasts high strength and very low weight. With the body and spring perch being manufactured out of anodized high-strength aluminum, you no longer have to worry about corrosion locking the two together. The materials in the new SAs allow pain-free height adjustability with ease with our threaded body. All non-aluminum components (upper mounting stud, lower mount mono-ball) are treated with corrosion-eliminating processes such as chroming, heat treating or using stainless steel. Don’t settle for heavy steel components.

BOA MOUNT, THE NEW STANDARD IN CORVETTE SHOCK UPPER MOUNTING: An idea taken directly from its much more expensive bigger brother, the Feather Light Generation DA; the new BOA mount is a no-compromises solution to Corvette shock upper mounts. Our mount is a zero-maintenance, completely sealed design that allows the FULL articulation required for the Corvette suspension. A common problem in coilover mounting for the Corvette is how to effectively mount the upper shock to the chassis without losing much shock travel and articulation. Common solutions are a clevis design that severely limits shock travel and will effect ride quality, and a “pin top” design that relies on compliance in consumable rubber bushings to deflect and bind the shock, creating an unsealed mount needing eventual replacement. The BOA MOUNT suffers none of these shortcomings as it is a solid mount similar to a control arm ball joint (quiet, durable, maintenance free), that is locked in place and then articulates with the suspension utilizing a low friction internal monoball that is sealed from the exterior elements. On top of all of this, the installation procedure could not be any easier. A simple easy to torque washer and nut retain the whole assembly. If your coilover doesn’t have the BOA mount, be aware of the potential future problems. Take a look at the video to see the new BOA MOUNT in action!

THE CIRC SYSTEM, A REVOLUTION IN REMOTE CANISTERS: A premium feature on the SAs that is unique to Pfadt is the CIRC (Concentric Integrated Remote Canister) System. The idea behind this innovation is to implement a standard racing concept – the remote reservoir – in a lightweight, easy to install package. We integrate the remote reservoir with the shock to maximize suspension stroke for a very smooth ride on the street. The CIRC more than triples the gas volume over a standard coil over. Accomplishing this was no small feat because the remote canister is actual mounted radially AROUND the shock body itself. The result: a large gas volume that keeps the shock operation consistent over a wide temperature range and throughout the stroke. The bottom line: Consistency and performance over the life of the shock. This system permits the entire shaft/piston assembly to operate quickly, efficiently, and last a VERY long time as wear is at a minimum. Get the most advanced racing remote canister on the market for your street suspension. Anything less is a compromise in ride quality. Take a look at the following illustration to see how we package the upper BOA MOUNT and CIRC SYSTEM for maximum shock travel and extreme lowering.

EASY ONE-STEP RIDE HEIGHT ADJUSTMENT: We make ride height adjustments easy to give you the ultimate control in setting your ride height and corner balancing your car. Included in our coilover kit is the single tool that you need to adjust the perch and tighten the set screw to lock the perch in location. Very simple, strong, and reliable. This single perch adjustment is a result of having ALL of the suspension travel required for the Corvette built into the shock body, since features like the BOA MOUNT and CIRC SYSTEM are used to maximize travel and stroke. Any other design is forced to limit the travel range. Our design is the most optimum for the Corvette and will deliver repeatable results time and time again.

FLOATING PISTON INTERNAL DESIGN: The most effective internal design for a performance shock that needs to last a lifetime of street use is the floating piston design, or “non emulsion” design. This design separates the oil volume from the gas volume and allows each to operate consistently despite changes in external conditions. In a standard emulsion shock, the oil and gas are free to mix together and can result in inconsistent performance when operating at low speeds and high speeds respectively. This is not good for the operation of the shock, as inconsistent performance correlates to inconsistent control of your Corvette’s wheels and suspension. Enter the “floating piston” style that isolates the two volumes and moves freely within the shock cylinder. Our floating piston design utilized in the Feather Light Generation SAs will keep your Corvette’s suspension predicable and controllable for a precise feeling on the street and track. GM’s Z06 and Z51 shocks don’t have oil and gas compromises, neither should your coilovers. Be sure to run floating piston shocks on your Corvette. Take a look at the diagram to see how the designs differ.

SIMPLE AND ACCESSIBLE DAMPING ADJUSTMENT: Have you had a hard time adjusting your current dampers because the adjuster is at the top of the shock, hindering your ability to make quick changes from street to track? That will not be a concern for users of the Feather Light Generation SAs because of the inverted design, which places the adjuster on the bottom of the shock in an easy to access location. No special tools are required, and no “adapters” that can frequently break are necessary. All that is required is your hand to grasp the easy-touch rotary knob on the bottom of the shock and dial in your setting with a precise and repeatable feel. The shock adjuster will adjust compression and rebound in one device, so you will not need to be an expert to keep both dialed in at all times. Up front you will feel 40 distinguishable settings with the rear having 24. The adjustment range encompasses soft to stiff valving for customers wanting to fine tune their ride quality or race track set up. The valving in this system will allow you to run very comfortably on the street and then increase the damping for track use if needed, or even higher to accommodate custom spring rates that you spec for your specific Corvette. There will be no guesswork in where to dial in the suspension as we provide a comprehensive tuning guide with the coilovers.

DURABILITY: As part of Pfadt Race Engineering’s ongoing effort to support the Corvette community with the best and most advanced chassis and suspension products, the Feather Light Generation series of coilovers (SAs and DAs) are the pinnacle of street performance, track results, and unbelievable reliability. Part of our evaluation for these coilovers has been our in-house, Pfadt-designed, DAMPER DURABILITY RIG. We have run all versions of current coilovers through rigorous testing on this machine for weeks which simulates tens of thousands of miles and literally millions of cycles. Being able to control the testing allows us to test at worst case scenario forces and articulation angles. We’ve also track tested and street tested the SAs to cover the complete set of circumstances. Take a look at the video below and get and idea of what a Pfadt coilover goes through to qualify it as suitable for a Corvette installation. Overall, the idea of moving to a Corvette Coilover suspension is going to give you a huge leg up on other Corvettes in terms of handling and street drive-ability. Removing the transverse leaf spring and OEM shocks will yield a true independent suspension which eliminates any “crosstalk” and harsh ride that the OEM suspension is known for. Not only will this solve any unwanted driving characteristics, but it will also give you the ability to tailor your Corvette’s ride to your specific taste with a large range of ride height and damping adjustments. Whether you want a stiff ride that is nice and low, or a soft ride that is comfortable and at stock ride height, our Feather Lights will accommodate all of the possibilities. If you get a new set of wheels and need to adjust to accommodate the new sizes: no problem. Your new stance is just a quick turn of the spring perch away.
