More on Spring Rates real quick. 8K is the shortening metric measurement of the spring rate in this example 8 kg/mm (Pretty Common). What this means is that if you apply 8 kilograms of weight to the top of the spring it will compress 1mm. If you apply another 8 kilograms (16kg total) of weight it will compress another 1mm. The other spring is being measured in pounds per inch; in this case 500 lbs / inch. If you apply 500 lbs of weight to the top of the spring it will compress 1 inch. Now if you apply another 500 lbs of weight it will compress another 1 inch so (1000 lbs will = 2″ of compression). The Formula to calculate Spring rate Kilograms to Lbs, Kilograms x 56 = Spring rate in lbs/in, so 8k x 56lbs = 448lbs And do the opposite to go from Lbs to Kilograms, Lbs Spring Rate / 56 = Spring rate in KG/mm so 500lbs/56lbs = 8.9k

Very good video. excellent explanation of how coilovers work. I just changed out the Tein coilovers, which I never really liked, on my Z to Powetrix R/T's with Swift 7/5 springs. The Teins were quite harsh even at the softest setting. The Powertrix are perfect for the street. Haven't been on the track with them yet.

Are you saying 8 Kg equals 500 lbs and 6 Kg equals 336 lbs?
@BuildTheoryZ3 жыл бұрын
Thanks for watching! In this case 8 kg or 448lbs. What this means is that if you apply 8 kilograms (or 448lbs) of weight to the top of the spring it will compress 1mm. Same Thing for 6k or 336lbs. 8.9k would be equivalent to 500lbs. Easy way to calculate this is each Kilogram equals 56lbs, so 8k x 56lbs = 448lbs, same would work to divide, 500lbs/56lbs=8.9k. Hope this Helps! let me know if you have any other questions.

@@BuildTheoryZ a kg is only about 2.2 lbs. Not sure how you're calculating that.

The 000’s of pounds is for an inch maybe which is 25.5mm..?

@@SpeshulFX the important part missing is that the distance traveled is included in the calculations, so instead of (8kg = 448 lbs), it's (8kg/mm = 448 lbs/inch)
