Okay, I know this has come up before...
What is the proper orientation for rear springs of a progressive nature?
Right now, my Teins are set with the dead coil on the bottom, I'm pretty sure they're in upside down. However, will I see any change in the ride characteristics with the dead coils up top? Does it matter? I know it takes 5 minutes to flip them and find out, I just want your opinions on the dead coil thing. Thanks.

Mine went up.. You might possibly feel the dead coils overlap eachother during a bump, if in upside down.. not that i know for sure, but I think there has to be a difference, my springs were very specifically marked to put them in the one way.

Yea, I'm wondering if flipping it might change the ride characteristics at all.

if it has any normal lettering make sure you can read right side up

my dead coils are down

its so easy to change, just test fit them for looks and performance. thats what i did when i had drop springs. I forgot which way i ended up, im on coilovers now.

My dead ones are down also, i have tanabe df210.

It might depend on who makes them, not sure if they are all the same.
