Spring rate calculation

^I see what you’re saying I think. But let me make sure I’m doing the right thing here.

I am on Sportline springs now, the Koni yellows are on their top perch in the rear, and bottom perch in the front. Getting GC’s with 10k front and 8k rear will allow me to lower both the front and rear another ½” to ¾”. Am I correct in that assumption?

I thought I had this all squared away, but maybe I’m taking what you’re saying out of context.

I don't think it'd be that bad. With our multi link suspebsion we can use stiffer springs due to how much movement there is in the suspension. That red sedan with the white bay is running 20k/18. I asked him and he said its stiff but not horrible.

You should be fine, I was just saying so you can get some more info.

Your front end is a lot heavier than our 4cyl so I'm sure 10kg will atleast get you to 23.5" all around on the lowest settings.

Rears for some reason can go a lot lower than the front.

Don't let my last post confuse you too much, I'm sure with 10kg front your car will look perfect wity your current setup.

^What about 10.7k? I basically have to choose between 9.8 and 10.7 for the front.

Wow....so, when we ask for custom rates from Eibach, do they automatically use the Swift springs?

About spring length, I can tell you how low I am looking to go, but how would I know what spring length to go with in the F/R?
