I just got some linear Suspension techniques 1" lowering springs and I was browesing the mazdatrix website and saw the spring rate
check this...

FRONT
Manufacturer Rate
Stock 95
Racing Beat 130
Suspension Techniques 120
Eibach 70/185

REAR
Manufacturer Rate
Stock 90
Racing Beat 80
Suspension Techniques 120
Eibach (non-Turbo) 85/165
Eibach (Turbo) 90/165

so is the same spring rate better to be the same all around or varied, I guess you can always adjust your strut braces.........

 

not necesarrily...if you're unsure about what you're doing then you prolly will not go wrong with a totally equal setup.

But the varying spring rates at the corners changes the driving characteristics of the car. For example...(keep in mind that I may be thinking about this backwards here) if you have a higher spring rate in the front and a softer rate in the back your car will tend to understeer when pushed. Has to how bad depends on the how soft the rear is. Now if you have a softer front and a high rate in the rear you will tend to oversteer. The rates you want really depend on what exactly your driving style is.


Note: Higher rate in the rear=good drifting

good way to get an idea of this is by playing Gran turismo in the same car with the spring rates adjusted.

 

whoa, im a third gen guy so call me ignorant when it comes to second gens but are those spring rates correct. seem really soft for stock. i think the third gens are three times that. could also be that i could care less about stock rates and always want more. ditch the cadilac ride ill take bulldozer feel.

Thanks direct from the Mazdatrix web site......but I always though 3rdgen had a better ride...

 

Shut up you know it eats us FC guys up inside.

You want it stagered. For example, k2rd's coilover setup uses 350f/225r.
