This sound drives me nuts and is almost painful. I've seen some diffuser to combat this. Suncoast have some that are screw on and another company (Blackstone?) has some that attach with sticky tape. I'm leaning toward the former, as they seem more secure.

Any feedback or comments from anyone who's installed these?



Thanks

Bothers me to, but with Cayman, not an issue with windows up. Enjoy the journey!

The AWE Wind Diffuser that's mentioned in the thread that @MLJJ linked to was the third mod I made to my car. First was an invisible rear license-plate bracket, and the second was the clear front side markers -- then the diffusers, all within 30 minutes of each other.

The AWE pieces work phenomenally. (Porsche really should design the A-pillar triangles that way). Well worth the price, and installation is very simple.

I'm wondering if this buffeting issue is limited to the Cayman, or if it's just that I rarely drive w/ the windows down and the top up. Going to have to experiment some.

My Boxster did it a bit with the top up. I fixed it with two bits of kydex bent into shape and slid behind the 'triangles' on the door.

Has anyone actually installed the AWE trim?
- Does it really eliminate the buffeting with the (Cayman) window lowered a little or do you still have to lower both windows to equalise the pressure in-and-outside the car?

- Is the install really as simple as they make outon the website? I have never removed trim, safe the cover for the soundactuator fuse.

I can confirm they make a huge difference, installation takes less than 5 minutes and is very easy. I also experienced the same buffeting in my previous 911 (991.2) and used the same wind deflectors.
The plastic also blends well with the window trim, assuming you don't have gloss black.

Thank you. Is the install really as simple as removing the top end of the door trim nearest the plastic triangle? These items are super expensive in the UK (shipping from the USA is $40 alone on top of the $79 for the item) and I don't want to end up buying this and bottling out.



Thanks again.

Unless you've got the "Hidden Screw", which is then a more involved process.

You guys must be really good if this is only a 5 minute job!

You need to check on the 'AWE Tuning' UK website, they have a store near Manchester and online facility. My knowledge is that they are easy to fit on the Boxster/Cayman 981 and the 911 991.2. For the 991.1, different story, you have to strip out the door panel and air bag cover to get to the retaining screw. For the 718, I don't know but I would be pretty sure you have the simple not complicated access to the retaining screw. I bought mine online for a 991.2 from the UK AWE store. There should be a little fat black triangle thing on the inside (see first photo) behind the bigger flat triangle on the outside which you are replacing. You just prise off easily the inner triangle (from the bottom up as per instructions included) to reveal the one retaining screw.

They do make a difference but don't completely eliminate buffeting with roof up but one window or both down or half way down. The Blackmill ones just stick over the top and according to posts on the Rennlist 911 site they work better (have a bigger lip) but don't look so neat. They're also dearer at $130 online especially when you then factor in delivery cost from the US as not available anywhere in UK. The AWE ones are about $79 online from the US but then delivery on top and you can get hit for import duty too. So the UK AWE ones are our only real option. Mine were £90 (rip off Britain as usual) plus £8 delivery from their website, the only supplier available.

I must say I don't think I would bother again. They are much thinner, flimsier and cheaper looking than the bits they replace although not noticeably so when fitted. Close to £98 is ridiculous but I guess they are low volume plastic pressings so no economies of scale. Come in a nice box though with instructions and a free lollipop.

Thank you @Peter.

I finally had the AWE diffusers installed a couple of days ago. I haven't had the car much over 75mph since then, but they've made a big difference on my C. My build date is 12/17 and I assume it was an easy install because they charged me the minimum service charge (1 hour).

Yeah. Looks like a lot of work for a simple diffuser. That being said driving at speed with the windows down rattles the brain!

The first one is fiddly to figure out, maybe 10 min tops including opening the box and checking instructions.
The second one went on in less than 60 seconds


On the road at freeway speeds they made a big difference.
I'm on the track next week I'll update on the effectiveness when I get back.

I must admit that I have yet to drive with the windows open. I've never liked getting buffeted by the wind in any of my cars. Maybe I should try it though as I would expect the aural experience to be totally different!

It’s pretty bad imo. Last time it happened while I was accelerating onto the highway. I was like WTF is going on!

Blackmill has another option that sticks on with durable double sided tape. The fins are more pronounced than AWE and will perform better.
