Guess I'll be looking at the Koni adjustables to go w/ the springs....I knew it was going to be expensive, but holy.....Ohh I understand that the car would understeer.... but imagine how flat the car would be through the corners and how god awful the ride would be...
Yeah I have seen it before... I actually watched it a while ago when I wasn't interested in the STi more about the other cars making no more HP on high octane...Well part of the car would be flat, the other part would be confused.
Pasting the suspension link twice. Weeeeeeeeez. Watch the 5th gear octane video yet wiggum? It's pretty good!
Those rates make no sense in the front. What is that, 350% stiffer than stock? I've never seen a street application that was that much stiffer than stock.Well now your car falls under the Sti example . Turbocharged for the !$&)!(& win!
Well, I don't believe it. In all the suspension theory I've read and the suspension experience I have, nothing would lead me to believe those spring rates would work.The spring rate was a result of the high mounting point of the double wishbone suspension and the characteristics are different over the strut type suspension. I will say that the roads in the Tokyo area are pretty nice compared to what we have locally and that probably has something to do with it as well.
As for the car understeer I am pretty sure they set the car up neutral or with a bit of oversteer. All of the guys there are into running track events and racing in one form or another. If they are happy with the way the car handles that is a good sign. You could always adjust the dampening a bit and get the back end to come out a bit quicker ( my type of driving style )
Stick with stock or spend the money to go to KW or HKS. KW may work better on the Mazdaspeed since they were made for the heavier V6 too, but HKS's coilovers are still fantastic. Your can probably run rear Koni shocks, but I don't know if the front inserts were still fit.
