```					Spring-Rate Calculator - Front Suspension

The steps below will help you to find an approximate spring rate for your coil-over
application. Enter your suspension measurements in the white boxes below.

*Yellow fields denote calculated cells, you do not have to enter values in them

Calculate the rear spring rate instead…

1 - Determine Sprung Weight
Corner Weight:                   0 lbs     Use an accurate racecar scale that will weigh each corner
(1/2 of the front weight)                           of your car. A trucking company scale meant to weight
80,000lbs may not be accurate enough for a 3000 car.
Make sure the vehicle is loaded with driver, passenger and
cargo just like you will drive it or race it. If your car is not
complete, use the approximate weights below, or click on
the chart to see actual vehicle weights from our project
cars.
Approximation of Curb Weights
Body Type               Avg Weight     Corner Weight
Street Rod              2500-4000      625-875
Coupe/Convertible       3000-4000      750-1000
Sedan                   3000-5000      875-1250
SUV                     5000-8000       1250-2000
Street Trucks           5000-8000       1250-2000

Unsprung Weight:                    0 lbs     “Unsprung weight” is vehicle weight not supported by the
(1/2 of the front weight)                           springs. Examples include: Tire/wheel assembly; brake
rotors and calipers (or brake drums and components);
wheel bearings; steering knuckle; hanging weight of the
control arm (or trailing arms on rear axles); differential
and axle weight; ½ of the spring and shock absorber
weights. Unsprung corner weight is usually around 70-
120 lbs. If in doubt about your front unsprung weight per
corner, use 100 lbs.

Sprung Weight:                    0 lbs/in Sprung weight = Corner weight – Unsprung weight. It is
the weight supported by the spring and is the only weight
used in calculating spring rates.
2 - Calculating Motion Ratio
The “motion ratio” is the mechanical advantage (lever ratio) that the wheel has over the spring in compressing it.

Dimension A:                           1 in         Dimension A - Measure the distance from the control arm
pivot point on the subframe (centerline of the bushing) to
the point on the control arm directly under the center of
the spring or the “coil-over assembly.”

Dimension B:                           1 in         Dimension B - Measure the distance from the control arm
pivot point on the subframe to the centerline of the ball
joint.

Motion Ratio                          1            Motion Ratio = Dimension A / Dimension B

3 - Coil Spring Angle
Spring Angle:                       80 deg.        Using a protractor or similar measuring device; measure
the angle of the centerline of the spring or “coil-over
assembly” from the horizontal of the control arm. In most
cases this will be somewhere between 75 degrees and 90
degrees. Most conventional springs and many strut
suspensions are very close to 90 degrees, and 90 degrees
can be used for the angle. This measurement helps
determine the “force angle” and resultant spring force
applied to the control arm.

Spring Rate:               0.00 lbs/in sticky tires
With a preload of:                     in
Spring Part Number:

Preload is the distance you will want to tighten the lower coilmount on the coilover to compress the spring, this
will put shock compression near 50% of its stroke when the car is resting at ride height. This should be done
before the coilover is installed. To do this you will need a spanner wrench. Adding more preload will raise the
vehicle.
