Coilover Spring Rate Calculator
FAQs
How do I choose a coilover spring rate for drag racing? Choosing a coilover spring rate for drag racing depends on various factors like your vehicle’s weight, power, tire grip, and suspension geometry. Generally, stiffer springs can help with weight transfer during acceleration, reducing squat and improving traction.
Is higher spring rate better for coilovers? Not necessarily. The optimal spring rate depends on your vehicle’s characteristics and intended use. Too high a spring rate can lead to poor traction and a harsh ride.
What does 8K spring rate mean? The “8K” refers to an 8,000 pounds per inch spring rate. It means that for every inch the spring is compressed, it will exert a force of 8,000 pounds.
Does higher spring rate mean stiffer ride? Yes, a higher spring rate generally leads to a stiffer ride, as the suspension will be less able to absorb bumps and vibrations.
What is 10k spring rate? A 10k spring rate means the spring will exert 10,000 pounds of force per inch of compression.
What is a good preload for coilovers? A general rule is to set preload so that the suspension settles to around 60-70% of the total available travel when the vehicle is at rest.
Should rear suspension be stiff or soft for drag racing? In drag racing, a slightly stiffer rear suspension can help with weight transfer to the rear tires for better traction off the line.
How do I choose the right spring rate? Consider your vehicle weight, suspension design, tire grip, power, and intended use. Consulting with suspension experts or experienced racers can also help.
