Spring length and perch question

[Xit40]

I'm interested in Doing some suspension work on my car and have decided that I wanna put Hypercoils in, 375 in front and 450 in the rear. This should work well overall for what I want with my car being a daily driver. I'm just wondering if anyone has a place they would like to recommend? Also what length should I use? From what I've found on here 8" seems to be what people are using. With a adjustable perch will I be able to raise the ride height up back close to stock if I want to cause it snows here and well I like driving my car. I plan on using them with Ground Control perches and Koni Yellow struts is there anything else I need to complete the suspension? I remember reading the Ground Control upper mounts are junk and I should get something else can someone help me out here? Thanx a bunch.

are you sure that's not backwards?

RRE makes a nice front plate for $190/pr.

You'll need spacers for the rear upper control arms.

Your springrates are insane, as pointed out less gently above.

Thanx. Yeah I was kinda tired when I wrote it. I meant it the other way around. What can I use for spacers or where can I pick em up? Also wondering where is a good place to pick Hypercoils up and if they can be raised up to close to stock height while on perches?

I have Ground Controls with the ride height pretty close to stock.

Ok new plan unless someone can tell me where I can get Ground Control Perches. I talked to them and they said they only sell it as a full kit. They gave me some places I can pick up adjustable perches but I don't know what size they need to be to fit on Koni Yellows (I.D. and height). Or better yet where can I pick up some Koni Adjustable Perches. Would I need anything else to make them fit besides the perch? Oh do I want 2.5 I.D. or 2.25 I.D.? All help is appreciated. Thanx

I'm actually pretty surprised that they wouldn't sell you just the collars.
You could always just buy the kit and sell the springs.
