Wrong forum, I know, but more likely to get a response on here

Has anyone done this with a factory fitted part?

Made a mess of my 435d when I took the old aftermarket spoiler off before vt

I have a oem cf lip to replace the std one on the m340

I am worried it’s installed using beta link and the paintwork will get damaged removing

Watched some videos, hairdryer, fishing line etc, what to use to remove adhesive?

I used strimmer wire last time, it was too think and left hundreds of saw lines that I had to get machine polished out

Any experiences appreciated

I agree that factory ones are a little harder to remove. Definitely same approach though just more care.

Warm day
Tape all around the body work nearby
Do everything slower
Take breaks
Have a little swear in the garage
When you have some sections lifted, try flowing a little warm soapy water into the next section, walk away and leave for 30 mins


You want to do it in 10 minutes but it's a better result doing small sections.

The residue removal is the worst part though. Would say a machine polish at the ready might be advisable but not always necessary.

Are factory ones fitted with Betalink?

Don’t know, seems strange they would as you couldn’t get it off to fit a mp one

Had one fitted at a BMW dealer body shop last month, he made a point of telling me they always glue them due to the risk of them coming off with tape (yes I know it's ass-covering) as he wanted to confirm that I'd likely never be able to take it off again. So with that in mind I'd assume they do the same in the factory for similar reasons?

If it’s glued then they can never fit an aftermarket m performance one through?

They probably have some 'special' BMW tool for taking them off that would cost any mortal more than a car to buy

So the spoiler arrived with no tape, 3m vhb? I only need 6 mm for the back edge, trying to understand the top edge, there’s no rebate, so the spoiler will lift by tape thickness ?

All the G20 spoilers are stuck on with tape.
Have fitted half a dozen M Perf kits to them now.
I will say that they are very well held
On however.I use heat gun and windscreen Cutting wire ,then afterwards remove the residue with tar and glue remover.If you’re careful it will leave no damage.
The M Perf spoiler is beta linked on.

Would Molybdenum wire, 0.08mm do? It’s that thin it’s hard to see if I’m careful that it can damage the paint

Probably, or fishing line or dental floss. Just make sure to heat up the tape well first.

Going to use my steamer

Steamer tomorrow, with floss, doubled or tripled and no rushing this time lol

Then I need to find some 70% ipa and tape
