We do not recommend using the 4056 2 with cargo coils or above stock height cars, as the bump stop may contact the cross brace. UMIs adjustable upper a arms with taller ball joints are designed to work with factory height spindles. UMI is not responsible for fitment issues which may arise from using incompatible components.
