OK guys, this is the way I installed my splitters. I am sure there are other ways to do it, but I did it like this

I wanted to make it easy on my self, so I took my bumper off, you don't have to, but then again I wanted to be easy

Then assemble your tools...

Drill,
Drill bit,
Bolts,
Nuts,

I painted my splitters to match my body paint (Yes Alpine white, not just any white)

No DIY on "how to paint" sorry, I didn't see the point in making one for that, and honestly, if you need a DIY on how to paint, humm, please don't...

Any who, you need to position the splitters first...



Now by that I mean, EVERY corner needs to be aligned PERFECTLY with the bumper!







Then you need to mark your holes, I used like a yellow paint pen, something that stands out...



Then choose a drill bit that is slightly bigger than the bolt... then drill the holes away....


OK, my personal touch....

I used bolt that were round on one end and put them in with them facing the top part of the bumper....

WHY? So that you can tighten them by pushing down on the bolts while using a (In Example 13mm wrench) easily...

then slap them on and put bumper back on, and enjoy the new look!
