I searched everywhere for a similar rattle and it goes away if I adjust the driver's side rear window just a bit.

Is the roof liner easy to pull back to inspect the structure?

If you're worried about braking performance on a track and using a convertible, you're doing it wrong
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Car is a 2004 911. When the top is up and you drive, there's a bit of a rattle in the top. At first I thought it was coming from the electric lock mechanism, but now I'm not sure. I feel around the roof while driving to see if I can put my hand over a spot and get the rattle to stop, but haven't found it yet.

It's my wife's car and she hasn't said anything about it...and I'm not going to say anything to her. But if I can find out where it's coming from and fix it, I will. It's one of those sounds the grates on my nerves just a bit.

Hello All,
Selling my 2015 BMW M4 Convertible as something else has caught my eye.
This M4 Convertible has every option available I believe as you can see from the window sticker.
Car also has a clear bra on the front of the car.
Exterior of the car is perfect. Interior is also in great shape as you would expect from a car with 4500 miles on it. Never been in an accident, clean carfax.
Please let me know if you have any other questions. I'll try to add some more pics tonight.
Thank you
I took the car out this morning and was paying closer attention. It doesn't seem as noticeable when I'm in the driver seat. Pretty weird.
Will keep hunting around to try to locate it.
Check where the top connects to the front by the sun visors. That piece can get loose and cause a rattle. I think there are two allen screws behind a plastic piece that pops out.
Lower the rear windows just a tiny bit and see if that makes any difference. I searched everywhere for a similar rattle and it goes away if I adjust the driver's side rear window just a bit.

Don't let the stock brakes scare you -- they're FANTASTIC. This is coming from someone who had a 911 Turbo S with the CCB's. I was hesitant, and drove both, and the CCB's on the BMW are not a huge step up from stock brakes. Absolutely not worth the extra cost.

Interesting... even on the track?
My previous E93 M3, i had to upgraded to StopTech Trophy BBK with Endless pads before it was trackable with no worries

That said, the CCB's will obviously perform better on the track. I still think you'd be perfectly fine with just some pads and fluid with the stock brakes, or at least, that's what most other M owners are finding. There is a MASSIVE MASSIVE difference in brakes from the E9X to the F8X. I own the F83 currently, and owned the E93 previously
Stop worrying and go buy OPs car!

How so?
Name a car that I can take for a cruise off PCH, enjoying the great top down breeze, and then, take that exact same car to the track the next day/weekend?
I'm not out for track times, I'm there to have fun. Brake fade and not being able to stop on a dime are not fun, especially on the heavier convertible. Now, if I cared about track times, then I would get a track specific car. But for someone who goes seldom (once a month tops), The M4 vert is the only car that I can do dual purpose.
SL63 out of price range. Ferrari T also out of price range.
I'd love to hear about any other amazing hardtop verts (like this BEAUTIFUL M4) if you have any other suggestions.
Haha, that's why I put the
after it
I own the F83 convertible, obviously we both get it
I still think stock brakes will be ok with proper fads and fluid in this car, and there's a company that makes vent ducts already.
I'm done replying here -- let's keep this focused on OP. GLWS!
