Koni Adj Shocks - Another question

Postby avera01 » Fri Oct 11, 2019 2:20 pm

Hi Brian, I hate to beat a dead horse to death, but I have a followup question to the new Koni shocks.

I read of drivers utilizing Koni adjustable perch shocks with stock ND GT springs and been competitive on the track.

So at which perch height will the car remain at stock height using stock springs?

How much lower does the car get when on the next step/perch down?

Thanks for your patience.

Well after doing some more research, I came up with the following but conflicting answers:

1) Stock Springs top perch should give you stock height

2) RoadsterSport Springs should with top perch should drop the car around 1/2"

3) The confusion for me lies with the Progress springs. The the difference between the top and middle perch is 20/30mm depending whether its a Club or Sport version; i have a GT ST. If the middle perch was presumably the original standard height for the shock, then the combined affect of the old Koni and Progress springs should drop the car around 1.5 to 2". That leads me to conclude that with new Koni using the top perch and Progress springs, the drop is around 0.75 - 1".

So perhaps someone can verify/correct my math and thinking. I prefer not to lower the car more than 1/2", maintain same GT comfort and improve handling within these parameters. I find the stock shock (suspension) a bit too wavy like (up/down) motion, especially on concrete road/highways. I already have the RS sways which really makes a noticeable difference in body roll.
