Run on our Roehrig Shock Dyno, this chart shows a different color line for each of six damping settings. Unlike an engine dyno chart, shock dyno charts offer relative information and must be taken in context. For a full discussion of dyno charts, see our Dyno Chart educational piece:
Our innovative Delrin/Aluminum mounting system – standard on all coil overs since October 2008 - is the best solution for the challenges of properly fitting a coil over on the Corvette. Our coil over mounts offer:
- Type-III hard anodized aluminum cup for incredible hardness and wear resistance
- The combination of the hard anodized aluminum cup and the Delrin creates an incredibly quite, wear resistant, low friction pivot requiring no lubrication to allow the suspension to work smoothly.
- The mounting system was developed with the philosophy that no part should serve only one purpose. So what was once a bulky system comprised of a clevis, spherical bearing, bearing housing and associated hardware totaling nine parts is now an innovative, lightweight , compact, space saving, solution of only five parts.
- Because we were able to drastically reduce the number of components we were not only able to reduce the mass of the system but also gain valuable space that can now be used for increased shock travel and nitrogen volume leading to even higher shock performance.
The bottom line - you don't have to compromise friction for packaging space with our mounts.
The photo below shows our Pfadt Coil Overs on the left and a clevis style mount on the right that we tested and abandoned several years ago. Notice how our mount maximizes shock/spring travel while the clevis mount wastes valuable shock travel.
Some will tell you that if you've got 16 positions of damping adjustment, 15 of them will be wrong. We would argue that for 16 cars you need 16 unique settings, not to mention the needs of dual-purpose (street and track) cars. Our single damping adjuster controls both compression and rebound. The range of adjustment provides a wide range of damping to accommodate both daily drivers and dedicated track cars. For example, most people like to drive to and from work with our coils set around 8, while for track days they'll increase the damping to 12.
We supply recommended starting points that offer a well balanced, well engineered setup that we actually run on our own cars. It's the best of both worlds. Proven on our 2008 NASA National Championship race car, we race with success on our Pfadt Coil Overs.
One of the key advantages of our coil over kit is the flexibility with setting ride height. Our shock bodies are fully threaded and thread into (or out of) the lower mounting cup giving you the ability to adjust the overall shock length by about 3 inches. It's no problem to maintain stock ride height or slam it nice and low. The important thing about changing ride height by using our threaded body is that you don't have to sacrifice shock travel and spring pre-load to lower the car.
Innovating, engineering, and constantly moving forward, Pfadt will always blaze the path for new and improved suspension solutions for your Corvette.
And you don’t even have to take our word for it – take a school at Spring Mountain, Texas Driving Experience, or The Corvette School and test drive our suspension for yourself. These prominent schools look to Pfadt Race Engineering to provide their students a Corvette equipped with real track suspension.
