Spring rate calculator

Postby Midlana1 » 12 Jan 2011, 18:32

If you buy some springs sight-unseen, and the seller doesn't know the rate, ask him for the wire diameter, OD, and the number of turns, then use this tool to get a good idea: http://www.proshocks.com/calcs/coilsprate.htm

Another way, if you have them in-hand, is to simply stand on them and measure the compression.

Spring rate = Your weight / Amount spring is compressed.

What spring rates have you chosen for your car? At a guess I would say 350lb/in rear and about 200lb/in front... but I know it depends on lever ratios etc....

Can you confirm these rates are ball park? Summit is having a fall spring sale. :lol: I will need to adjust the front rates for the outboard setup...
