Installing 18" wheels on P400 caliper clearance and crash block fix

I wanted to swap out the wheels on my P400 for some 18" ones to give it a slicker appearance. However, the rear caliper fins got in the way, so I carefully ground them down. I used some paper to double-check the clearance and shifted the wheel weights to make sure there'd be no rubbing. The front wheels were hitting an aluminum crash block, which I was able to take off with just one bolt. Now everything fits perfectly, and the ride feels much better
 
Great job, just keep an eye on the calipers and crash block areas over time since grinding and removing parts can sometimes affect cooling or safety . As long as theres proper clearance and nothing rubs under load or full lock, you should be fine, but it's worth checking things regularly, especially after longer drives
