"Q.What are the benefits of switching to a coil-over front suspension?
A. Better handling and better ride quality! When the spring is in the stock location on the control arm, the minimum spring rate for performance handling is 700 lbs/in. Better handling can be had with higher spring rates, but ride quality begins to suffer with rates over 850 lbs/in. A coil-over kit allows the use of wheel rates that are much higher than those obtained with an 850 lbs/in spring in the stock location. This will dramatically reduce body roll and brake dive. Other benefits include easily adjustable ride height, the ability to fine tune corner weights, ease of bumpsteer measurement, less weight, and a wide selection of available spring rates."
