Chevrolet Performance Suspension Kits (not shown)It takes a tuned suspension to complement your Sonic’s performance oriented wheels and tires. The engineers at Chevrolet Performance have designed the Sonic suspension components to optimize vehicle handling performance, and improve the stance at the same time. This kit uses the “RS” fast-reacting shock valving but lowers the “RS” by 10mm, and the base model by 20mm. It utilizes the “RS” front struts assembled with a different spring and jounce bumper. The rear springs and shocks are redesigned to accommodate the new suspension travel. This package lowers the center of gravity of your vehicle, which results in improved handling.
