I'm lowered on Novitec. I never scrape when lifted and I'm dialed down pretty low. Here is an easy way to ensure you won't scrape:

1) Lift your car, approach the spot in question at angle (which you should always do)

2) Have a friend measure your nose clearance. Add 1/4 inch if you want for any approach variance.

Boom! Now you know the maximum you can lower on Novitec before you scrape.
