Really?

Eibach crossfire kit doesn't give you options for spring load rates, ground control allows switching the spring out because it uses a standard and very affordable common spring.(they have custom made race spec adapters top and bottom for all four corners to put in these other springs and the price is rediculous cheap for what you get and the quality) Eibach crossfire kit is also not an adjustable system. You get some lowering compared to stock but you can only fine tune with the OEM spring pads (not very much) and takes a lot more time and energy.

I thought most of this was already posted in these ground control posts.

If you are just looking to get a better look and don't care about getting exactly the way you want and are not concerned about fine tuning and switching out parts to dial in suspension performance then just get the Eibach crossfire kit and be done.
