DYI CF front splitters

Guys, anyone knows how to place the front CF splitters?

You will notice that they will only fit right one way. Just play with them until you have them lined up right, then get yourself some double sided tape and put on the inside where the splitters will contact the bumper. Expose the adhesive and then line them back up as carefully as possible and attach to bumper.

Do you have to drill them in?

Nope.

Does the 3M tape really hold the splitters when you are driving 100mph??

It is SUPER SOLID! There is also one factory screw you use as well as one you have the option of drilling.

step 1: use painter tape and tape your car 1st before dry fit to avoid scratching the paint.
step 2: dry fit and move around until you find the desired position. 1 hole should line up to the existing screw.
step 3: put 3M tape on, preferably 1 long one instead of a lot of short ones.
step 4: remove the painter tape on the car, clean the surface well, use alcohol and let dry if you have it.
step 5: put on a glove to avoid letting your sweat touch the surface. unscrew the screw, fit the splitter, screw it in, just a little bit, not too tight so you can move the splitter around. position to the desired position you had before. remove 3M tape, and use pressure to push down. when secured, screw the screw in tightly.
step 6: enjoy and drink a beer

Thanks guys. Got today and ill try without drilling another whole in. BMW wanted to sell me their adhesive stuff but they told me if I use it I cannot remove it so I went with the M3.

Now does anyone know where to get the instructions from. Not that I can't so it looking at the you tube video, but I thought it came with instructions. Does any one have it?

you shouldn't need instructions, you can only put em on one way. Use 3m tape on edges, (i would use a simple self tapping screw underneath) and you're done. Really like 30 min worth of work

Get the splitters on further.

Its really hard to beleive that doubble sided tape and one screw will hold the splitter at over 100 miles per hour.
This is the only thing thats holding me back from putting it on my car.
But i have to say that our cars look great with front CF splitters.

Tested mine going 150 plus mph and they are all intact...no issues.

100 mph runs will push the lips onto the car more, now 100mph in reverse would be a different situation.

Thats good to know. Very interesting, race cars rarely go over that speed on most race tracks, but they still use supporting rods for splitters.
Anyone knows what is the real purpose for those rods?

135mph on the back straight at Mosport. No issues.

He is right. I placed these long ago and they are fine with 1 screw and tape as indicated above. One thing to know is that these are super super light, it's almost like holding a paper file.

The OEM side splitters really do not provide much downforce as an actual splitter (flat bottom panel lip). It is mostly cosmetic. Tape and 1 screw is fine.

As speed increases, pressure on the splitter increases. The rods keep the Splitter from distorting from aero, and additionally distorting from impacts with the road when the suspension and aero compress the front. Some regulations require the splitters to be in a fixed postion as well.
