Yeah mate exactly the same concept for all of them. Just take a look once it’s offered into place and check where the fins end up. If it’s a nice solid bit of plastic then send a little hole through.
When it comes to the front splitter just be aware of any wires or hose lines lurking about before drilling.
One thing I forgot to mention...the Maxton splitter comes with stupidly oversized fittings, I think they’re 8mm bolts and locking nuts...14 of them!! There’s no way in hell I was gonna drill 14 8mm holes through my bumper. What I did was keep all of the torx screws that’s came off of my OEM diffuser - 10 in total. I then used the torx screws Rieger provided to put the new diffuser on, then the old torx screws for the Maxton splitter up front. I just spaced them out equally - 3 on each curve, and 4 in the centre section.
Hope this helps, sorry to hear about the damage. Hopefully you’ll get a new one sent out ASAP!
