Theres also such a thing as "different sized tyres" 
Theres a reasonably big difference between 215/45/17 & 205/40/17.
In fact, 205/40 is 1.16" shorter! That could sovle the problem!
The other thing is if you increase the height of the car, and then install bumper extensions and side skirts, it looks like the car is really low...
