Need some help for 2014 F15 X5 M PKG Lower Spring

[Sam.W]

I just installed the H&R Lower Spring for my new F15 X5 M PKG. But I don't know why for the front, the height of my car doesn't change, and for the rear, it has been lowered. The parts come from E70/E71 X5/X6 H&R Lower Spring. They said the suspension system of F15 X5 M PKG are the same as E70/E71 X5/X6, so the lower spring can be fitted on F15 X5 M PKG. But now, front still looks like original height, and rear was lowered already. Who can tell me what is the problem? And how to fix that?

Thanks!
