These GMPP FeatherLight Generation coilovers differ from Pfadt's standard coilovers in spring rate. The springs chosen for this GMPP package is specially optimized for track only use. These are the rates that were developed exclusively for the Corvette Z06x, and are exactly what you are looking for if you need a track specific package.
Damping rates were designed and carefully chosen to work superbly for the c5 and c6 chassis, based on years in the Corvette racing community. From the independent rebound and compression adjustment, to the proprietary BOA low friction upper mount system, this package is engineered to drop lap times and put more Corvettes on the podium.
Taking a closer look at the entire design process sheds some light as to what separates the FeatherLight Doubles from the pack. There are key points of adjustability into this system that will allow Corvette owners to tailor their cars to any track situation and driving style. A few of these keys include:
-Independent Rebound and Compression adjustment
-Ride height adjustment
-Custom spring rates available
While these adjustments aren't new to the Corvette world, what is new is the Corvette specific optimization and durable material selection to reliably put distance between you and the rest of the field. BOA (Ball On Axis) upper shock mount system is an example of this commitment to reliability. The BOA upper mount is engineered
to smoothly articulate across a wider range of motion with minimal deflection and to minimize dead length. Extra articulation in the upper mount reduces bind along the shock shaft, and the reduction in dead length allows for the maximization of available shock stroke that would normally be encroached by a traditional clevis-style mount. Threaded shock bodies are notorious for collecting road debris and jamming spring perches, the ACME threaded shock bodies alleviate some of the stubborn lock ring syndrome that are common on traditionally cut threaded bodies. The inverted design of the shock it's self offers lower sprung weight than it's standard counterpart, but thanks to the use of an outer dust seal and inner oil seal you can rest assured that particulates will not make their way into the shock it's self. The entire package is capped off by a hard anodized 16mm shock shaft for low friction and extra strength, this is 3mm larger than the stock shaft.
The remote canisters not only move compression adjustment to where it can be quickly accessed without removing the wheel, but they provide extra gas volume to prevent pressure buildup in the gas volume under large shock stroke events.The increase in gas volume and the subsequent decrease of pressure in the gas volume versus a conventional designed shock means more consistent performance over the service life of the FeatherLight. Manufactured from high strength aluminum and connected to the shock via sealed braided stainless steel line, the canister it's self will perform flawlessly time and time again.
