The accelerator and foot rest were easy to install since the provided self-tapping screws can go right through the plastic material. The brake part was kinda a pain cause the screws didn't do the job at all even if the holes were pre-drilled. The screws would require too big of a hole, i don't believe it can be done without going over the edge of the metal brake plate. I ended up buying some smaller #6 bolts and nuts to attach them. Its just as secure, so i'm happy with them.
