Whats the difference. I just ordered some and the ones i got are more of a gold color then chrome and didn't come with the spanner wrenches. How do i tell the production date. It also looks like the rear springs are compressed all the way but from further reading it seems thats ok. The company i bought them from already said i could swap them out for another set, but thats a pretty big hassle. So doesn anyone know the difference between generation 1 vs generation 2.
