so wait, is it not a good idea to swap the rear springs to the front? and ksport doesnt have 5kg? cuz damn i was really gonna try what midnightmax did

It's okay to swap rear springs to the front unless you're super-slammed, in which case you might have to either raise your car or preload the spring to prevent contact between the lower spring perch collars and the lower mount collar.
It's not necessarily okay to swap front springs to the rear.
Come down to NY and ride in my car! 
Somebody should get in touch with k sport about this.. all of the springs on my D2s (9kg, 7kg, 5kg) were the same diameter and length...completely interchangable! I thought it would be the same case for the K sports...

Just a little chat I had with KSport. Thought I would share. I don't know if this information was already posted in the thread. I thought it was pretty cool.
ME: what the lowest spring rate you have for the KSports A32 Maxima?
ksportsupport: hmm, i would say 7/6
ME: oh i thought you had lower
ksportsupport: we do but the shock will blow, and it will drive like a boat
ksportsupport: a 4kg spring is not enought to hold the car up
ME: my stock is something like 2/4
ksportsupport: that is equal to 224lbs/inch
ksportsupport: stock is a progressive rate, which is totally different
ksportsupport: these are linear rate
ksportsupport: you cant compare these to a normal spring at all
ksportsupport: although yoru stock is 2kg possibly, with more pressure it increases up to 15kg
ksportsupport: so it will nto bottom out plus you can have the same amount of travel as you did with stock, otherwise when you lower it it will rub or bottom out
ksportsupport: when our spring is 224lbs/inch that means for evrery 224lbs. of weight the spring will compress one inch
ksportsupport: 9/7 is the best rate for handeling, and being able to lower the vehicle
ksportsupport: if you went with softer springs it will allow the spring to compress more, causing rubbing or bottoming out

Oops. Stock springs are linear rate, not progressive.
But the point is a good one anyway: if you lower your spring rates to near stock, you'll have to raise your ride height to near stock as well to prevent rubbing and keep your chassis from bottoming out. Since that's possible in the rear but not in the front, you're kind of limited in what you can do. Plus, you might have to add some preload since you might not have enough suspension travel to accommodate the lower spring rate.
In the end, why have coilovers if you're just going to have near-stock ride, ride height, and handling?

AFAIK, most kits were shipped with 9/6 but some people have said that their kits came with 9/7....
I wonder if there'd be a way to find out without having the original box.

Yes it will.
You'll basically have Tein basics, only with damping adjustment, front pillow ball mounts, separate height and preload adjustment, and different shock valving.
Compared to what you have now, expect better compliance in the front, no difference in the rear, slightly lower overall grip levels, and less understeer at the limit.

Is there a way to get money back for the slightly used 9kg springs? I'll have no use for them after buying 7kg.

It's not exactly night-and-day, but it is definitely noticeable.
Just remember, you might have to give up either your "Lowest in CT" title or your undercarriage if you lower your spring rate(s).

Hmmmm, I wonder. I shall contact k-sport to find out the spring rate my rear came with. If they are 7kg/mm, then going to 6kg/mm should make the ride in the rear a little more forgiving with the terrible roads here in Toronto. 
So after talking to ksport, I guess my set was one of the few that came 9/7 for the A32, so I grabbed a pair of 6kg/mm off them. How much of a difference in the rear do you think 1kg/mm will make? I didn't want to grab a pair of 5 and throw the 7 infront and all that cuz I am actually very satisfied with the way the 9 in front feel. I always found the rear to be a little to stiff, so hopefully this should smoothen it out a little 
Since I'm going with a softer spring, and that might rise the probability of bottoming out a little higher, do you think its a good idea to raise the dampening a little to compensate? Which will protect my struts better, stiffer dampening, or full soft?
If my experience is any indication, you won't have to worry about bottoming out with 6 kg/mm springs in the rear unless you're really really slammed. Even when I was dropped 4", I never ever bottomed out unless I drove over a hump or dip in the road that was too big for my approach/breakover/departure angles. Just set the damping to whatever you're comfortable with.
Not sure on the damping question though. Let me see if I can find out...

So has anyone ordered and then actually received a set of 8/6 springs with their Ksports? Cause I'm leaning towards that combination. A middle ground between 9/7 and 7/5.. 8/6 
Because of the normal crazy south dakota weather, i have been realizing how much temperature affect the ride quality. When moderate temps 50-60's degrees it takes a little for the shocks to warm up. But when the car has been sitting in 80 degree weather i take off and it rides soo much smoother.
I'm assumming its fluid inside the shock that causes it to expand contract in temp related environments has something to do with it. Part of it could be temp relation to the tire too, but i wouldn't think it would be to that big of a difference.
Anyone else exprience this? If it has been discussed before forgive me i have been trying to keep up with this thread as much as possible. Just giving a little of a review for midwestern weather. I can really see how people in hotter climates are very pleased with this setup.
