Ok I lowered my xB last week using Drop Zone springs and it looks great! I have had other lowered rides in the past so I expected a bad ride. Well I wasnt dissapointed! The ride on the interstate is great, in town though it is very choppy. It rebounds very quickly and Im not sure but it sometimes feels like the rear may be bottoming out on something.The only thing I can think of is maybe the rear shocks dont have enough travel? Any ideas? The springs are "progressive rate" whatever that means and I only have 2 coils on the rear that arent touching?
