technically, you could install them with 3M double sided tape on the rears without drilling. Just follow the factory tape that is already there, add some to the inner side of the wheel well in the splash guards.

That is an option if you don't have an electric drill or don't want to drill holes on your bumper. Took 30 minutes tops to install without drilling or having to take the wheels off. Will it hold you asking, more than plenty and more then secure. Just clean off the area where the 3M tape is going to lay down on with some dishwashing soap to strip any wax you might have around the area.

 

Just thought I'd add my two cents, here; I installed my complete set last night in about 30 minutes- that included the time taken to get the car up on the lift and pull all 4 wheels off. I had a friend helping me so he could drill while I had the guard pressed firmly in place, so that helped- but all-in-all a very easy job.

Yikes - that's rich.

I put mine on without much bother, or special tools.
I don't see why you couldn't. It's really no biggie, and certainly not worth $100!.
