Good to know that the KW's can hold up with those spring rates even though the clubsports are valved a little differently. I'm sure the V3's can take the spring rates I've gone with but not a big deal if I have to re-valve them in a couple seasons. I did not know KW offered linear springs. I contacted them last year and they never responded..
The swift kit is actually quite nice as they supply thrust sheets and vorshlag nylon spring locators. I've done a ton of reading on these springs and they hold up really well and offer some unsprung weight reduction (its not much but hey I'll take anything I can get as its difficult to shave unsprung weight.
How does your car perform in terms of oversteer/understeer? I did quite a bit of reading regarding this and was worried about going too stiff in the rear which would cause traction and oversteer issues. I guess its more important to find the sweet spot between front to rear spring ratio. With my setup its about 10% more stiff in the front based on my wheel rate calculations. This should keep the rear end a bit more planted while reducing understeera bit (which these cars are setup for from factory).

I went with an 800lb rear to go with the 675 lb front and so far so good (stock valving)!
