Need some feedback on those who have bought Stillen bumpers
 

How is the fitment? Do they guarantee it? I'm about to purchase one and don't want to get stuck with a costly piece of gappy plastic.

My first one wasn't so great, but it was production number 1 off the assembly line.

second one fits much better, it comes loose on one side occassionally during track days, but I bolted it on myself with no adjusting or work on it. If the body shop had done it, I'm sure it would be perfect.
