What is a good spring rate for coilovers?
With a typical street car, you’re looking for the weight of the vehicle to compress the springs 25- to 30-percent. For drag cars, you will typically want between 30- and 35-percent of the spring to compress.
How do you read spring rate on coilovers?
Most commonly seen is a spring rate given in KG/mm or LBS/in. This means the weighted force / the space traveled. For example, 700LB/in would mean 700 pounds will compress that spring 1”. This can also be read as 12.5K/mm (12.5kg to compress spring 25mm).
Is higher or lower spring rate better?
As you decrease the spring rate, the suspension is able to conform better to road irregularities, and thus grip improves. With a lower spring rate, the force pressing the tire down remains higher longer relative to the amount of travel it has, so it contacts the ground much sooner.
How does spring rate affect ride quality?
The advantage of a progressive spring is that it can provide a variable ride quality-softer when the suspension is at a normal ride height, and stiffer as the spring is compressed, such as when the suspension is being pushed hard through a corner.
Does spring rate affect ride quality?
What is a good spring rate for drifting?
Race car stiff is out—for drifting, you want to use spring rates that are only a little stiffer than typical high-performance street coilover spring rates. For the super-popular 240SX, something like an 8kg front and a 6kg rear are good.
What makes a spring stiffer?
The amount of coils on a spring also determines the stiffness of a spring. The less coils you have, the stiffer your spring will be. In the case of a torsion spring, less coils give you more torque but less travel. In the case of a compression spring, it is based on the pitch in between its coils.
How do I make my coilovers smooth?
For a smooth ride, you need to soften both the compression and rebound on your coilovers. Fortunately, this should not be that difficult. Coilovers that provide these adjustability will also include a knob that you can just turn for adjustment. Note that not all coilovers come with adjustable compression and rebound.
Why are my coilovers clunking?
Clunk – If there is a clunk and you have confirmed that installation was done correctly, there is play somewhere in the suspension or there may be suspension components coming in contact with other components.
