How To Install BMW Rear Spoiler?

In order to install the Competition CF spoiler and remove the lip spoiler off our cars, I was wondering if there was a DIY way doing so.

Spoiler removed:

1. Make the area tidy

2. Heat it up using a heat gun (make sure not to damage the paint; do it in sections, 3-5 inches at a time)

3. To detach the spoiler from the trunk, use fishing line.

4. To clean the trunk, use 3M adhesive remover.

Although I’ve seen it in person and it is one hell of a bling bling, in the real world, daily driven NO… just a bling bling… I’m contemplating purchasing one for myself.


I was just wondering whether there was a downforce boost with this spoiler that was published. It doesn’t seem to be really different from the OEM.

When compared to 3M heavy duty tape, Betalink is much harder to remove because it is so much stronger. A section of my friend’s spoiler, which was linked to his e90 via betalink, was broken in the attempt to take it, and the trunk was also damaged.

How to put in a CF spoiler:

1. Employ the BMW Betalink-K1 (BMW pn 82-69-9-408-866)

Read the instructions.

This is just what I needed! I appreciate you; I’ll print this out and give it to my men. My spoiler arrived today and will soon be painted.

Hey guys, I still have adhesive on the rear portion of the spoiler after installing my CF rear spoiler with the BetaLink. There isn’t much space to work. What is the safest method and tool for removing excess glue?

I believe I cleaned up any stains with some of the betalink’s included solvent.

Yes, I have used it, but I’m almost out. I’ll see if thinner works and doesn’t harm the rear lip.

due to the fact that this spoiler is “taller” than the OEM spoiler’s lower profile. If it were only secured with 3M tape, it would be simpler to remove.

Even with 3M tape, it is most obviously not being “popped off.” A person can end their relationship with betalink if they work hard enough. So what exactly is the difference?

Does the presence of a rear spoiler matter?

As automakers worked to enhance the aerodynamics (the control of air flowing around a vehicle) of racecars and performance automobiles, spoilers began to gain popularity in the 1960s. Federal fuel economy laws later compelled automakers to enhance all vehicles’ aerodynamics in order to produce higher mileage ratings. At highway speeds, a car with less wind resistance consumes less fuel.

However, spoilers are also employed at the front to deflect air to the sides so that less gets below. When you mention the word “spoiler,” most people will likely picture a wing-style spoiler sitting above the deck lid of a car. The rocker panels’ side “skirts” double as spoilers.

Aerodynamic drag rises as a vehicle’s speed rises, requiring the engine to work more to maintain speed. Additionally, more air enters underneath it, producing “lift,” which lowers grip and weakens the stability of the vehicle. Front spoilers limit the quantity of air that enters the vehicle’s undercarriage. Spoilers increase downforce to keep the car firmly planted on the road in the back, where airflow tends to be more turbulent and produce greater lift.

However, spoilers are only a small portion of the overall aerodynamic picture. The design of the roof, back window, trunk, front bumper, size of the grille, shape of the headlamps, and other elements all play a vital role in controlling airflow.

Prior to going on sale, automakers spend millions refining a vehicle’s aerodynamics to increase fuel efficiency, increase stability at high speeds, and lessen wind noise. Many cars just feature a little “lip” spoiler built into the trunk lid and an air dam beneath the front bumper as spoilers. Although some performance models have more pronounced rear spoilers or wings perched over the trunk, this doesn’t always imply that the vehicle is more aerodynamic or has a higher top speed.

Sticking any appendage to the exterior of a vehicle is bound to interfere with the aerodynamics that were built into it, but a well-designed rear wing will behave like an upside-down airplane wing to produce downforce rather than lift. A poorly made wing could even reduce peak speed, stability, or fuel efficiency.

It should be noted that with such performance versions, the producers frequently do not assert that they enhance downforce or aerodynamics. That may be a subliminal admission that they exist more for show than for action. Spoilers, wings, and other “aero” hardware are also sold by dealers and aftermarket businesses, but frequently they are primarily for aesthetic purposes. Consider how many Toyota Camrys—the ideal middle-of-the-road family car—have an aftermarket decklid spoiler.

Additionally, spoilers sometimes have unexpected results. For instance, even though it stands up and obstructs the airflow, a spoiler that extends upward from the trunk of a performance vehicle or NASCAR stock car reduces drag. Similar to this, tests on aerodynamics have shown that pickup trucks with the liftgate in place have less drag than those with it lowered or removed.

How much time does installing a spoiler take?

1) Put on safety glasses before beginning the installation.

2) Measure the trunk lid with a measuring tape.

3) If you haven’t already, purchase your spoiler.

4) Put the spoiler together. The wing brackets must be positioned so that they fit together correctly before being tightened with a wrench.

5) Mark the spot where the spoiler will be. To mark the precise location of the spoiler installation, you will need a marking tool.

6) Drill the holes in the trunk or the area where the spoiler will be installed.

7) Smooth the hole edges with sandpaper.

8) Put the spoiler in place. For this phase, you probably need a friend to help you. Before tightening the washers and nuts, the spoiler must be mounted on the trunk of the automobile.

You shouldn’t be able to move the spoiler at all once it is placed. Check the locations of attachment, if you can move it, for items like loose washers and bolts.

Make sure to have the proper tools on available and a professional to assist you if you are a novice and want to help install your spoiler.

Any automobile can fit a spoiler, right?

A spoiler is essentially an alteration you make to the car’s body that alters how air flows around it, which not only enhances aesthetics but also improves performance. Depending on the style of spoiler, it can be mounted on the front or the back of the vehicle. The three main types of spoilers—wing, lip, and pedestal—affect the air characteristics on the car body in different ways. Almost every type of vehicle can have an accessory attached, such as a universal lip spoiler.

Will my car actually drive differently if I spend more to have a spoiler put to it? Tim from Ottawa

Warning: The likelihood is that your sedan’s spoiler serves little use other than to make it look sporty.

According to Dr. Martin Agelin-Chaab, assistant professor of automotive engineering at the University of Ontario Institute of Technology (UOIT) in Oshawa, Ont., “the great majority of spoilers out there don’t do anything — you don’t get any bang for your buck.” They only function correctly when installed, and even then, only at speeds of at least 100 kilometers per hour.

Aerodynamic lift, the force that tries to lift your car off the ground, is supposed to be revealed by spoilers. Your car is supposed to be pushed onto the road by them.

Dr. Ron Miller, an engineering professor at Carleton University who has worked on race-car design, says that spoilers are typically used to improve downforce because they deflect air upward, creating a downward force on the car. “This aids in keeping the tires firmly planted to the pavement, improving the car’s grip and, consequently, its cornering ability.”

Agelin-Chaab claims that spoilers might help lessen drag. Additionally, you’ll use less petrol if your car has less air resistance. But unless you’re taking the freeway, you probably won’t notice the difference while you drive the kids to soccer.

At 120 km/h or above, 50% of fuel is used to reduce drag, according to him. Therefore, at high speeds, even a little reduction in drag can have a significant influence on fuel economy.

Agelin-Chaab continues, “But a spoiler only works if it’s cutting through the air at the right angle.”

“On more expensive sports vehicles, factory-installed spoilers are quite effective. There are likely many others out there that are less effective; some automakers even claim that their spoilers are merely for aesthetic purposes.”

According to Agelin-Chaab, fitting a spoiler correctly takes at least three hours in a wind tunnel (the UOIT’s costs $700 an hour). If you’re installing one yourself, you can perform a coastdown test to determine how much drag your car is experiencing.

Even while a spoiler might not improve the handling or fuel efficiency of your automobile, it can’t harm, right? I hate to be a spoilsport, but a spoiler that is improperly installed could disrupt the airflow surrounding your car. A spoiler may or may not interact correctly with the flow surrounding the vehicle to improve things because it was not incorporated into the car’s aerodynamic design, according to Miller. It might even make matters worse.

Understeer can be brought on by a poorly placed spoiler that gives the back wheels too much traction.

The straight rear wheels often take precedence over the twisted, less-grippy front ones, which might make the automobile more reluctant to turn, he says.

Do automobiles actually need spoilers?

You don’t need a spoiler unless you drive extremely fast vehicles. Spoilers only function at quite high speeds and do nothing at low speeds. Over 100 kmph is where the spoiler’s impacts can be felt, and you must constantly exceed this speed to notice any changes. If you don’t drive at this pace or higher, your car’s aerodynamics will be hampered, making rear spoilers all but useless. So just answer “no thanks” if you’re asked if you want to use spoilers on a car that you know you won’t be driving at speeds consistently above 100 km/h.

Can I use 3M adhesive to affix a spoiler?

It’ll keep. With 3M adhesive, I put trunk spoilers on both my e92 and previous vehicles without experiencing any problems. Make sure the trunk is spotless and clear of debris such as grease and oil. After I finish cleaning the trunk, I usually wash my hands just to be safe.
