Wind deflectors behind headrests

However, making your own can be costly, and very time consuming. By hand you must measure out each hole, mark them, and then comes the drilling. You can't use just any old drill, no sir. You must use a Dremel tool, and with the expensive diamond-dust carbide-aluminum tip. Then, meticulously you must drill out each hole and... here's where it can get really expensive: one drill-bit per hole. Further each hole diameter must be measured with a micrometer and, again, not just any off-the-shelf-micrometer... for it must be able to meaure hole diameter down to .000000000000000000000000000000001 of an inch for, if just one of those holes isn't perfectly drilled, well, you can imagine the shame and ridicule by fellow Porsche owners. Finally, the rubber edging must be sourced from Indonesia, as it is made from a special "Rubbercone", a hybrid material from the rubber tree and hard-to-find silicone tree.

That is why many people just break down and spend the money for the set.

1. Ordering a set from the Internet will take ~10 minutes, and ~$325 brand new.

2. Making your own will take ~375 man hours and $3K-$4K in tools. It's all those ****************ing holes.

You obviously have not tried it yourself.

A Dremel leaves the edges too rough even with the diamond tip. I used a flat bed CNC with a Co2 Laser, available here: https://www.bosslaser.com/boss-lsr-hybrid.html

The Indonesian rubber is too sensitive to UV radiation and fades to a grey after a few months of full sun. The Melanesian rubber is the one to go with.

I sourced the uncut titanium hyper-alloy aluminum sheet here: https://www.customcargrills.com/Perforated-Grill-Mesh.asp

And the carbon fiber infused UV resistant rubber edge here: https://www.customcargrills.com/Grill-Trim.asp

I have lots of extra material and I will not share.

There may be cheaper sources, but if you were looking for the cheapest source, you'd be driving a 1990 Miata, not a Porsche Boxster.

Starter986 is right. Matter of fact you didn't even notice/mention the zip ties used in the picture of the person you quoted.

Well I thought it a bit rude to... manners and all that. I'm British after all ;-)

Those look great! Especially with your color.

With mine (Seal Gray)? I still like the black.

Mine came with them, I installed them a few times and used zip ties to keep them from blowing out or being easily stolen. However, I found the passenger side screen blocked my blind spot, sounds stupid in a convertible with the top down, but combined with them being too fragile and expensive I decided to quit using them, no difference in wind noise, just looks. Maybe I will build a pair like 78F350, I would be using zip ties anyway.

The center windscreen on the other hand makes a noticeable difference in cockpit turbulence and noise and is definitely worth having.

ooops, im repeating myself LOL

yeah i was talking about the perforated alu within the rollbars. have bought some sheets and rubber and going to attempt to make my own when they get delivered.
great news about being able to prise them off.. that makes matters a bit easier

thankyou

This vid will help. If the little black plastic anchors come off with the pad, simply unscrew them off the pad and push them onto the roll bar before you put the pad back on.

Yes, if you make your own they probably won't have tabs

Here's what the OE screens look like and the 3 tabs:

Here's a pic that shows the tabs on the original wind deflectors:

I do not recommend allowing an elephant to sit on the original deflectors.

When I first made mine, I was going to have a folded edge to fit inside the rollbar. It was unnecessarily complicated.



My recommendation is to just use a flat sheet cut from the perforated aluminum. Make a cardboard template that rests against the rollbar slightly within the curvature of the back. I didn't have to remove the padding to apply the zip-tie, but just slid it underneath. A thin strip of 3M tape applied to the rubber edge will secure them and be less visible than the zip-tie - I may do that later.

I sold every set I had and never missed them. Free money. Just saying

I wasn’t happy with the amount of air coming thru the stock units so I added curved plexiglass sheets I found online. They fasten to the stock units.

I, too, have purchased and installed the plexiglass wind blockers into my OEM mesh inserts.

Works great.

look ok tbh, they'll do instead of spending £150 on them (cost about £20 all in)

in retrospect i think i should have maybe gone with less metal between the holes (not sure of terminology of that)
ended up painting it black since it looked a bit weird being aluminium coloured when the car is dark gray and nothing really alu coloured anywhere on the car.

They look great! And the zip-ties blend in nicely!

They do look good as well as the 'fuzzy dice' hanging from the mirror
