Don't take out the wind deflectors it bends anyway so it won't really hurt if you scrape.
You can't have it all in life...You lowered it so expect the worst.
It would be really hard to drive it if its your DD.
I do have an ARK grip but never scrape it yet.
I usually plan my route if Im using the Z to avoid high speed bumps.
Its really a PAIN but thats the price you pay for looking good.
