spring rates can not be compared car to car due to motion ratios. To say a spring rate works for certain situations is not always true due to valving of the dampers you are using as well.

1lb/in->kg/mm just divide by 56
kg/mm->1lb/in just multiply by 56

it is not completely accurate but majority of coilover springs have varying rates with compression anyway

 

I know its going to be off by a little bit. But at least you have something to gauge your spring rate when you start looking for a suspension.

 

owned!!

 

hows that being owned? its showing the general idea of what to look for.

 

Spring rate conversions kg/mm to lbs/in

This conversion rate is close as possible! It is just something for you guys to be able to gauge what spring rate is best for you style of driving and what suspension you should choose!

1lb = 0.45359237 kg
1in = 25.4mm

.45359237 / 25.4 = .017857967322834645669291338582677

1lb/in = .01785 kg

kg/mm to lbs/in

Green area: Street Use or Daily Driving only (Do not drive all the way slam down)
Purple area: Street and Track on weekend (You can slam car down)
Red area: Track only (Too stiff for daily driving)
-----------------------------
2.0 = 112
2.5 = 133
3.0 = 168
3.5 = 196
4.0 = 224
4.5 = 252
5.0 = 280
5.5 = 308
6.0 = 336
6.5 = 364
7.0 = 392
7.5 = 420
8.0 = 448
8.5 = 476
9.0 = 504
9.5 = 532
10.0 = 560
11.0 = 616
12.0 = 672
13.0 = 728
14.0 = 784
15.0 = 840
16.0 = 896

I found this on another forum. I hope this will help you guys choose what spring rate is best for you style of driving!

Fixed*

those bright ass colors lol

 

lol i dont know i just always wanted to say that..:fu:

 

Good post, just make the colors a little easier to read.

 

good info and owned? not quite loluke:

 

ninja edit.

 

I know I wrote the threat for people who needs to know about spring rates. Is this worth sticking this threat? I am not saying that you should just because I wrote it. It is just my opinion that this will help a lot of people looking into buy suspension and what spring rate they should look into get for their driving style.

I think we need a COMPLETE suspension FAQ (that would include this) instead

 

yes but it will probably take a week to go from camber to instant centers lol It would really need to be organized before hand

 

Any progress report on this? :x:

On a side note, does 7k front/8k rear sound about right for the monthly autoX and daily driven otherwise? on the chart it seems like a good tradeoff between comfort and stiffness.
