I have seen a number of install videos and posts. But does anyone have any pics to use as a guide on where the best place is to install the tape on the spoiler is? Ideally for an F33.
A couple of close ups of where OEM or other high-quality 3rd party spoiler manufacturers have positioned the tape would be helpful.

Thanks!

All through out the edge.... the entire spoiler surface that touch the car surface.

While we are in on the topic....

Does anyone know the proper thickness of tape that should be used?

Im installing an F80 spoiler soon and was wondering what mm thickness the factory would have used to originally apply it.

I just bought 3m vhb.... it say 45 mils thickness.

We will see soon enough...in just clean an OEM F36 spoiler. It does have a lip on it where the tape is... I'm also worried, but the tape that was there originally is not thick either.

I don't see any other tape thicker than 45 mil. Maybe non 3m tape.... but I have a few disappointment using those.

VHB is good, held up on my F30 2013 just fine. I just wanted to add...

PREP WORK IS EVERYTHING

Clean everything with alcohol, do not assume surfaces are clean out of the box.

I've seen shit explode on itself because people just "stuck it on".

Like the homies said, "it's all in the prep."

I highly recommend purchasing 3M adhesion promotor specifically meant for their acrylic foam tapes. Don't use the clear VHB tape. You want the gray acrylic foam tape as these are incredibly strong once stuck down in place. Definitely figure out what correct mil (thickness) you need for attaching your spoiler.

One last tip, once you have the 3M tape affixed to the spoiler undo about an inch or so of the liner from the ends, just enough for you to pull away. The purpose of this is to give one the ability to 'dry' mount for a precise fit with the tape in place. Once you are happy with the location, hold the spoiler in place and pull away the double-sided tape liner for a perfect fit. You basically have one shot to get it right so this would prevent any curse words or objects from flying. I learned this pro-tip from the official BMW mudflap install instructions.

Sspade is worried about thickness because the OEM spoiler have a lip (CURVE out EDGE) not flat where the tape is placed...I guess so the spoiler sit on the trunk flush with no space between the metal trunk and spoiler.

Of course good prep is needed

There are a few 62mil thicknesses available and lots of automotive specific products for badge application. 3M 5962 would be a good option if you ever plan to remove it and keep the lip intact. 3M CV62F is a commercial vehicle tape that would be more permanent.

Thanks....

I already bought the vhb 5952... I'll find out soon enough.

There is also this 3m RP62... its 62mil. I don't know the difference but it is acrylic foam too

That would also be a good option.

Be sure you get the original 3m double-sided tape in the original 3m package since the imitation tape does not last and falls apart in the heat.

This is the original 3m tape I got for my spoiler and other trims. This bonds really well and have had no issues. https://amzn.to/2SLn2Nt

I got the cheap spoiler for my 2013, it came with knock off tape. I used my own, and it held at near sub-sonic speeds, ok maybe triple digits just fine.

PREP WORK

Yay

Grey over clear of course. I'm going to have to buy some of this adhesion promotor, new to me and never know when you might need some.

Per the OPs question - heres some pics of the M Performance front splitter for the 4-series M Sport as it ships. It’s an amazing piece — the finish, weight and fab precision are aerospace quality.

Each side of the splitter only has 4 pre-installed automotive tapes - with the very useful ‘flag ends’ on each one to facilitate easy removal of the tape backing once the splitter is located in place during installation.

It’s unmarked tape (no 3M branding) and it’s actually thinner than the standard 3M foam tape. (BMW can likely go thinner due to above mentioned fab precision as everything is exact dimensionally and surface-wise.)

As you can see, BMW has the tapes installed just in critical additional spots, complementary to the splitter’s built-in structural mechanical fastening locations which match up to the cars bumper/underbody points. They apply the tape approx. 3/8” to 1/2“ from the part edges.

Hope this is useful!

OP, if it is a trunk spoiler the double side tape should be close to the edge... 1- 2mm close, not like this front lip

I guess for some reason alot of people call the front lip as a spoiler.

Front lip aka splitter... aka spoiler... aka air dam.. so much damn names. So not to confuse .m.i said trunk spoiler

[visionaut]

Since the OP said he had an F33 vert I assumed he meant front vs rear ‘spoiler’. I didn’t think there was an OEM F33 rear ‘spoiler’. ??

I don’t disagree that you’d want tape near the edges on a rear ‘spoiler’ that’s hanging off your rear deck having no mechanical attachment.

Last time I used 3M 06397 (1.52 mm thick - 3M recommends it for spoilers), I used it instead of 1.1 mm thick tape as the latter wasn't sitting too well on the edges and it looked like there wasn't enough elevation for the tape past the brim to form a snug bond with the trunk surface, only on the extreme edges on the front end though. I wonder how it compares with CV62F? After 2 days it started lifting on the edges, very minor but noticeable on closeup, my OCD kicked in and I removed it. It was really hard to remove. I did use the adhesive promoter on the spoiler side and 90% isopropyl alcohol to clean the trunk surface. Maybe I should have clayed it too?

Now I recently bought Betalink to do the job permanently and not waste another 2-3 hours removing and clearing the spoiler in case the edges don't stick perfectly. Then I started reading some threads mentioning Betalink a nightmare to work with so I don't know what to do.

If anyone wants OEM CF M Perf spoiler and Betalink let me know Or maybe I'll just do it

Mines taped. Previous owner of my car beta linked the last spoiler and it appears to have messed up my paint. screw that stuff & a pain to take off.

Betalink is supposed to be permanent, he shouldn't have removed it. Is it OEM M Perf CF Spoiler? It's a bit tricky on the edges.

It was the OEM M Perf spoiler. If you betalink, i'd expect to be happy with how you place it and never expect that shit to ever come off. Strong stuff.

I mean is your present spoiler the M Perf CF spoiler? Curious to know how it's holding on the edges with the tape. Mine started lifting on the edges that's why got Betalink. I don't plan to remove it after install and don't want the edges sticking up 😭
