Taller tires is the best way to go. It's what I did to get my Cervini kit off the ground a little bit. My car is lower with Steeda springs and I still make it over speed bumps and up driveways without scraping any part of the kit thanks to the taller tires. I'm running 245/40 tires up front on 20x9 rims and 295/35 tires on 20x10 rear rims.

 

do you have a picture that shows the tires and how far your bumper is off the ground?

 

Here's the best pic I have right now...



Here's measurements I took for someone else in another thread:

Side of the front bumper by wheel well - ~4.75"
Belly pan under front bumper - ~3.25"
Lowest point at the front of the bumper - ~4"
Lowest point of the side skirt around exhaust tips - ~4.75
Lowest point of the exhaust at the clamps - ~3.25
