I'm a little confused by choosing spring rates for my e91 touring.
I'm going to install coilovers but I have no rear springs.
So I'm going for custom made srings because it is cheaper for me to do that.
My rear setup is pretty flush, (10J et17 r19) and I am going to be low. (I mean really low not the usual -4cm e90post forum height.) I am not looking for comfort.
so my question is what spring rates should I go for e91 rear setup?
I'm thinking about 680 lb/in
