Hi. I run 17" rs7's on my 3 door and it's set pretty low on coilovers. You won't need to remove the splash guards but you will need to roll the arches at the minimum, I removed the front bodykit, cut the steel arches away, cut the lip off the plastic bodykit and then stuck it back on. My wheels haven't touched the arches since. You might need to trim the bumper a little as well, but it depends how low your car sits. Hope this helps.
