Spring Rate Chart for Evo X

[PsyTrix]

-- 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.

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

i'd love to know where you can pick up a set of hypermax's for under $2500?

[PsyTrix]

From the states you can - are you after Hipermax III street or the sport version? think Ive seen them for around 1650 (Street version) somewhere - will post again if i find the link!

[bye2u]

this is taken from evoM.. so the prices are USD...

[arutha]

oh ok that makes more sense. cheers guys

[PYLee]

yeap those prices are indeed in USD but the Hipermax III (non sport version) can be gotten for just under $2000 USD delivered
