Questions about Roush rear valence

[MKYR]

So a local deal has came up and I like the idea of quad tips. However I've got the corsa extreme. What tips could I use that would work with the roush valence?

Also, I have reverse sensors and apparently it doesnt come with holes for it. Whats the process for that?
