200# Rear Coil-Over Springs

The 200# Rear Coil-Over Springs from Competition Engineering are precision-engineered suspension components designed for street performance, road racing, and handling-focused builds where adjustable ride height and consistent spring rates matter. These coil-over springs deliver the stiffness and control needed to transform vehicle dynamics, replacing soft OEM springs with a tuned 200 lb/in rate that balances responsiveness with drivability. Whether you're building a track day machine, improving cornering performance, or dialing in a street rod suspension, these rear springs provide the foundation for serious handling upgrades.

Each pair features a 2.5-inch inner diameter and 12-inch compressed length, engineered to integrate seamlessly with coil-over shock kits commonly found in performance suspension systems. The 200 lb/in spring rate—stiffer than typical street springs but accessible without extreme ride harshness—provides measurable anti-squat characteristics during acceleration and reduces body roll in cornering while maintaining enough compliance for bump absorption. Black powder-coat steel construction ensures corrosion resistance and clean aesthetics; the durable finish protects against moisture and road salts over seasons of use. This rate is ideal for vehicles weighing 2,500–3,500 lbs per corner, making it suitable for compact performance cars, lightweight muscle cars, and modified imports.

Installation requires a coil-over shock platform or compatible adjustable shock absorber with matching 2.5-inch spring seating; these springs are sold as a pair and mount to the rear axle assembly. Proper spring rate selection—confirmed by vehicle weight and suspension geometry—is critical; overstretching or underloading a spring compromises both performance and safety. Competition Engineering's reputation for precision manufacturing means consistent rates across both springs, eliminating left-right imbalances that degrade handling. Builders upgrading from stock suspensions should verify their shock top hat diameter and seating style before ordering; pairing with quality rear shocks, bushings, and alignment work maximizes the benefit of these 9.35 lb springs.
