Call Omni and check to make sure yours aren't on their recall list... I know a few years ago (like maybe late 06/09), they were having problems because they milled the tophat (I believe) too thin and the full coilovers were breaking. Pretty sure they recalled the ones that were made, and I know they fixed the problem. Just might want to check.

But aside from that slight problem, I have heard nothing but good things about them. Comparable with Teins in quality.
