My IC sits about an inch lower then my front bumper. I just went out and looked. And I noticed my stock chin guard or whatever you call it is beat to hell. I haven't really had a chance to see if I'm going to have problems cause my KB developed a problem right away so I haven't driven it much since I installed it. On the upside, it goes into the shop on Tuesday to fix this thing once and for all. I plan on replacing my front facia so I'll probably hear that go as I rip out my IC. Not much room under there. Good thing it's no longer my daily driver.
I also looked at my front wheel well and it doesn't look like my 70lb SC lowered my front end anymore. But I have a very stiff set of springs.
MM has some great urethane isolators.
