Drilling CF splitter

JD3 · 01-07-2013, 03:45 PM

Hi guys, I've got CF splitters (the two that go on L and R) and they have depressions on the bottom where screws would go but no holes. No, these were not bought off eBay

.
Question is, do I drill pilot holes? If so, what size hole and what size screw? I know this stuff is strong but brittle and the last thing I want to do is to crack the CF obviously.
Thanks for any advice

Depending on the layout of the holes you may be able to reuse your OEM screws from under the bumper.

I ordered the OEM splitters and mine came with the holes pre-drilled. According to the directions, they mate up with the existing screws/pins under the bumper.

Ahh, I didn't know there were screws under there already. I don't plan on putting them on until spring so I haven't messed with it much. Good to know though, thanks.

Yeah, I'm surprised these didn't.

Vendor said that people are simply using the tape so they stopped having holes drilled. Suggested I just use the 3M tape so that's what I'm going to do.
Thanks.

Thanks.

Combo of tape and screws assuming you can re use the OEM ones will be simple and most effective for a secure fitment. 150 mph winds can do some weird things to loose fitting carbon

Mine came the same way... There's one screw underneath the bumper already.. instructions say to use 2 screws, but I might try just the one (and not drill into my bumper for the second hole), and some extra 3M tape.

I might try it this weekend in the cold haha. I'll let you know how it goes.
