Yaris wheel rate ratio (06+) ?

[dsc_pat]

Hello,

Does anyone know the approximative convertion ratio for spring rate / wheel rate on a yaris 2006+ ? motion ratio...

I would like to compare spring rates with the honda equivalent, in wich i have experience with. I don't know how to calculate it myself, and I am wondering if any of you guys knew about that ratio.

For those wondering what the hell I am talking about...here is a quick explanation :

Let's say you install 500lbs*inch springs on a SUBARU, It might feel very very very stiff driving the car.

If you install the same 500 lbs springs on a Honda Accord, it might feel pretty ok.

The difference here is in the suspension geometry design, wich result in a different wheel rate.

For those numbers people :

(**HYPOTHETIC NUMBERS, NOT REAL NUMBERS)

subaru : 500lbs * 1.0 motion ratio = 500 lbs wheel rate

accord : 500lbs * 0.7 motion ration = 350 lbs wheel rate...

The feeling won't be the same.

So, i would like to know the motion ratio of the Yaris, to know what I am buying and looking for as springrates for my yaris...

thanks
