Packaging is cited as both an advantage and disadvantage of the transverse FRP leaf spring, as compared to coil springs, depending on the application. The FRP spring is typically set low in the suspension, resulting in a low center of gravity. It also allows manufacturers to avoid tall spring mounts, thus resulting in a flatter load floor about the suspension. James Schefter reports that, as used on the C5 and later Corvettes, the use of OEM coilover damper springs would have forced the chassis engineers to either vertically raise the shock towers or move them inward. In the rear this would have reduced trunk space. In the front this would have interfered with engine packaging. The use of the leaf spring allowed the spring to be placed under the chassis, out of the way, while keeping the diameter of the shock-absorber assembly to that of just the damper, rather than damper and spring. However, in other applications, such as race car designs, the need to span the width of the vehicle resulted in significant design limitations. Coil and torsion springs present better packaging options for racing applications. FRP springs also have limited availability and selection as compared to coil springs. Higher cost has also been cited as a disadvantage, when comparing FRP springs to coil springs on production road cars.
