I had to trim mine as well. Its not hard and it does not detract from the external look of the VX (unless you do a major job like Billy (Triathlete) did .

I used a Dremel with a small cutoff wheel attachment to trim mine. It's quite simple. I can't imagine getting enough leverage with a hand tool to do it, unless you remove the front bumper cladding. I did mine in the parking lot of the the tire shop.
