What spring rate should I run?
Springs should typically be compressed 25-30% of the free length when supporting the weight of the vehicle. Drag race cars will normally use a lighter rate spring (about 30%) to promote weight transfer while a street car will use a firmer rate spring (about 25%).
What is a good coilover spring rate?
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 is suspension spring rate calculated?
To calculate the amount of spring rate you will need on order to meet your working loads, simply divide the load you will be applying on your spring by the distance you expect your spring to travel or compress under that load. The equivalent to that formula will be your compression spring rate as shown below.
Does spring rate affect ride height?
You should increase the spring rate from the standard rate. (If you increase the spring rate, the ride height will also increase, so please lower the lower seat.) When driving at the circuit, it is ok to lower the car until the tires nearly touch, but if you drive to the circuit, please abide by your local regulations.
What is the formula for calculating spring rate?
The calculation of spring rate is linear on extension and compression springs; unlike torsion springs where the force is radial. Knowing your spring rate will determine if your spring will function correctly under your working loads….Formula Symbols:
- k = Spring Rate (Spring Constant)
- F = Force.
- x = Distance Traveled.
Is a higher spring rate stiffer?
In simple terms, a spring’s rate is the amount of weight required to compress itself a single inch. It’s a universal measurement, it applies to everything from lowering springs to valve springs, and it’ll look something like this: 500 lbs/in. The bigger the number, the stiffer the spring.
How does spring rate affect ride?
A lower rate spring that lowers the ride height of the chassis with no bumpstop trimming, making the bumpstop more active, would feel about as stiff as a higher rate lowering spring with the bumpstop trimmed, making the bumpstop less active. Also, the amount of ride height lowering also affects suspension rate.
