Does anyone know if its a good drop and how the ridability of it is?

 

Which one? The sportlines or the pro kit?

I have an xB2 dropped on Eibach sportlines and it rides awesome. The drop is so low, too, so I have my wheel wells nice and stuffed. I rub a lot though.

If you don't want to rub, I'd suggest the Pro Kit, as they'll keep you close to stock setup, plus give you somewhat of a lowered stance.

Granted, I don't know the drops on these springs for the xB1 (and I don't feel like looking for them), but on the xB2, they handle very well.

Eibach is a great brand and you'll do well to use either of them.
