Damn that’s pretty low. You must be rubbing all over the wheel well liners at that height which is not cool sinces there’s a wiring harness running along the drivers’ side liner. If you want to stay low you should re-locate it before you burn right through it.
Anyways, why not raise the car back up a little and see if you still get those noises. Like the others said it’s simple. You dont even need to remove the coilover. Just loosen the lower perch lock and rotate the coilover body. Let me know if you need a hand.
