Spring Rate Chart for Evo X

Postby PsyTrix » Sat Jan 22, 2011 12:43 pm

-- Saw this on another forum and thought it would be helpful here --

I think it's time to start a sticky on all the different Springs and Coilovers out there for the Evo X. I'm starting to add in a "Street Price" which is an approximate average of prices seen with a basic google search and may not be 100% accurate. Just keep in mind that sometimes you get what you pay for and the lowest price vendors may or may not include the same (or any) support after the sale when it comes to tuning your suspension.

Springs and Shocks:

Conversion Chart:
Quote:

Spring rate conversions kg/mm to lbs/in (Data from Vankuen in the Evo 1-9 forums)

1lb = 0.45359237 kg
1in = 25.4mm

.45359237 / 25.4 = .017857967322834645669291338582677

So now we know that 1lb/in = .01785 kg

kg/mm to lbs/in
-----------------------------
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
