where the bumper didn't meet the fenders correctly. The only way to fix it was to shave and or build up the bumper with filler. The Jspec is temperamental, but if you leave it in the sun and let it get warm/take your time installing it right, it's 99% of the time correct looking. I can't speak on the fender liners because I haven't installed the front portions on my car.
