i would like to know where on the splitter to drill holes for the mounting bolts on the underside. if someone could do a quick phone pic of the underside of their mounted splitter, i'd appreciate it. thanks

 

Check out pix in this for sale thread.

I have a stillen splitter, but I don't have it like how the pic is.
I have screws exactly under where the double sided tape is attached along.
The pic of the link has it below (closer to the car)
I have way more screws than the pic as well too.

 

Same here. But directly behind the tape line.
I also threw out the screws that came with it, and used 13 larger diameter hex head sheet metal screws that come with rubber and metal washers.
Also drilled out holes on the extreme ends to allow longer bumper mounting bolts to attach
through the splitter. That way if I ever have to take my bumper off the splitter stays with the bumper.
If you dont, you need to remove the splitter, and reinstall new 3M double sided tape.

That splitter is not going to fall off!!!

 

i cant seem to find the pics i had but i used bolts/nuts instead of the screws it came with except for a screw at each end. i have 6-8 bolts just behind the tape line where it is a flat mating with the bottom of the bumper.

 

Just hold it up to the bumper and drill pilot holes through both the splitter and bumper and then secure it with the double side tape and nuts and bolts. I just eyeballed it using about 15 nuts and bolts with washers on each side. Check out my garage for pics. It's very secure and been on there since march, withstanding some extreme speeds.

 

Everybody keeps mentioning washers and nuts... are you guys removing the bumper to secure the backside with nuts?

 

I used these with a washer on top and bottom. No need to remove bumper, just drop the skid plate and do it. Drill pilot holes.

 

I saw this first hand and it is on there really well!

 

Lol. If it hasn't fallen off yet I doubt it ever will. I made sure of that.
