These race ready springs were designed for one thing in mind, cornering . These springs will lower the car 1” which is a much needed drop to get rid of that factory nose high look. These springs are a straight rate which makes the car very predictable in cornering, while giving the car a stable and tight ride. These springs work great for most racing conditions, and are rated at 640 lbs. A nice upgrade to these springs would be double adjustable front shock to really dial in your front end.
