Hi there, I couldn't find information as to what the stock spring rates for a 545i are. I'm talking about the sport suspension spring rates. Also, if someone could find the spring rates for aftermarket springs like Eibach and H&R that would be great.

TIA

I'm pretty sure almost all aftermarket lowering springs are progressive. Meaning its spring rate changes as the spring compresses. It's not a set spring rate when the springs are progressive i.e. eibach...
