front and rear springs... different.

[nnobody825]

My car is original stock. (non-pp)
I found something strange.



left: front spring label.
right: rear spring label.

Why is the rear spring with a pp label?
What do you think? normal? problem??
Again, stock and non-pp

I have no idea what springs they should come with but I think I read somewhere that the PP was set up be to more neutral so it may be they have the same rear springs and firmer front springs?
