Swift Metric Coilover Assist Springs 65mm (2.50") ID 68mm Length Each. Swift Springs have been coined to be one of the best springs in the world! Widely used in many famous racing series such as GT and F1 series. With the backing of 80 years of racing and industrial spring experience, Swift have created top-notch springs from hundreds of engineering concepts and theories. The end product results in the lightest, most durable, and most linear spring rate on the market. Swift springs not only can change the spring rate, but can offer other advantages such as noticeably lighter unsprung mass, smoother weight transfer, better ride quality, lower tire temperature, and increased ability to predict vehicle reaction.
Assist springs feature two major advantages. It provide a dynamic progressive-linear spring rate which adds a progressive feel to the initial portion of the stroke. The progression can increase ride comfort for a daily driver on the streets and highways. Once the assist springs are fully crushed, it transfer the rest of the job to the main spring. The second advantage is the ability to keep the main spring from coming loose during rebound and extreme cornering to prevent loss of traction. Assist springs are designed to be fully crushed at all times and always crush to the same height.
