I decided to put together home made wind deflector for cheap instead of buying one from IAP for around $280.

I'll be using Tifosi's measurements but instead of plexiglas I'll be using PVC frame and mesh fabric.

I'm still figuring out the best way to attach the frame.

One of the options (the easiest) is headrest, being that the frame is lightweight.

Question is: Can headrests be pulled out on '91 Veloce?

It can only go up so far, so before I use the force and break something I thought maybe one of you knows how to pull them out.

I'll post pictures when I get it done.

 

[Tifosi]

AFAIK, they'll snatch right up out of there.
If you wanna be really sure, move the back panel down a bit and look for big 'hairpins' on the bottom of the headrest posts
(tilt seat forward, remove the couple phillips screws at the bottom, slide the whole panel down in the groove)

If present, remove them and the headrest will come right out.

another design

Here is my version FWIW.
I tried attaching it against the headrest but found it was starting to rub the surface off the vinyl , so decided a self supporting system was better .
I have replaced the 2 outer rubbing strips on the shelf with 1" steel brackets .
10mm tube bolted to the screen slots into 12mm welded to the brackets
Triangulation pieces are just held on with wing nuts - takes about 1 min to remove if I want a bit more wind in my hair .
I used Tifosi's measurements ( thanks ) but there is a slight asymmetry - as I found out when I tried to put it in the other way round !
Hood clears it just fine .

Hi David,

Nice design on triangle supports.

I also built Tifosi's desing out of plexiglass. Built 2 in fact with different heights.

My bottom rests on the rear parcel shelf and the top is attached to the headrest posts using Velcro.

With no support at the top, how does your design hold up at highway speeds? Does it rattle?

Mine rattles a bit with the wind even with the velcro straps.

Let us know.

Thanks,

Vin

Hi Vin
Its pretty solid at speed . The other day it was quite windy and when a cross wind got on it there was a bit of flexing - but no rattling .
And to answer paukfast's original question - the headrests on my 83 pull right out - 'cos I just tried it . Other years may differ .

final product

Here is my version of wind deflector.
It turned out just fine, doesn't look bad and it works pretty good.

The best thing is that I didn't drill a single hole to attach it.
Just lift headrest slide the thing through and pop back in to place.
The whole thing is only 1 lb.

Total cost: $20.00

All materials found at Lowe's.

Looks to low to work?

 

[paukfast]

Looks to low cause headrests are all the way up.
When I fold the roof it just clears it, few millimeters...

It just couldn't get any higher.
I could have only made it little longer... has maybe one inch left.

This is 36 inches exactly.

 

[msiert]

Ohh......didn't notice that, my bad.

Paukfast:
GREAT idea! Would you be so kind as to post the dimensions and tell us what materials you used? It would appear that you used PVC pipe and painted it. What diameter of PVC?
The screen itself is what material?

Thanks for any ideas/tips as it would save us from reinventing the wheel - or, the screen in this case.

My best,
Dean

The wheel is nothing without the axle

I agree. Measurements and drawings would be GREAT!

I'll third that motion...that's a great looking windscreen

Thanks for the comments.
I was surprised myself the way it turned out.
It actually looks better in person than in the picture.

I used next:

-Two 1/2 inch PVC pipes
-Four 1/2 elbows (see picture, you have them in black too)
-Four 1/2 inch tees
-Pet-D-Fence screen
-Some spray paint (I used Valspar no chip plastic paint)

All can be found at Lowe's, probably Home Depot too.

This screen material is actually fabric. Vinyl coated polyester and it is very tough staff that feels nice to the touch and it looks good at the same time.

It took me long time to decide what material to use and this was definitelly the best option.

Dimensions

I am European so I used metric, but I'll give you converted units and you can figure it out.

-Lenght 36 inches (91.5cm)
-Height 7.8 inches (20cm) don't make it higher or it will hit the roof
-Attachment Tees distance 29.5 inches (75cm)

By "Attachment tees distance" I mean the distance between outer headrests rods. You can see from the previously posted pictures that that is the place of attachement.

You just slide the headrests through the tees and stick the whole thing back in place (seats). The headrests will lock in the first available and the highest position and at the same time give the stability to the frame, now Wind Deflector.

I wrote earlier that the whole thing weighs around 1lb, but I would say reather around 2lb. Still, very light.

Note: Make sure to include the lenght of elbows and tees in total lenght and widht when you cut the pipes and put it together or you'll be off.

As far as putting the screen together you can use many diferent options.
I used the easyest: Superglue.

All you need to do is cut the fabric lenght and widht X2, tighten it and put just few drops on the seem.

Trust me, it won't go anywhere. Once it dries it's like same piece of fabric.
It may turn little white-ish but then you can just touch up with little black paint.

If you are really crafty (which I'm not) you can sow two ends together.

I'll post few pictures of the frame before I installed it so you can see what it looks like when you put all PVC pieces together.

Paukfast, thanks for the info. I assume there must be a short length of pipe between each "attachment tee" and the tee of the frame. How long is this length? Just enough to join the two tees (i.e., are the tees touching) or longer?

Here are few more pictures of the frame before I put the screen over it.
Unfortunately I didn't write down all measurements so I don't recall.

As far as little piece of pipe that goes out and attaches to the headrests it was matter of trial and error. It all depends on what your driving position is. In other words how much you recline your seat.

The more you recline the seat the sharper the angle (and longer the pipe) between the little attaching pipe and the rest of the frame being that you want your deflector straight up.

These pictures will give you better idea.

 

[alfaporsche]

Great info. Thanks!

Hello all,

I also have been messing about with mounting a winddeflector (or diffuser as some call it) and this is what I came up with.
Only thing is that you have to drill a small hole in the seatbeltguides and place a 5mm helicoil in it to make sure it is holding for years to come.
The small grey clamps ,called 'polfix' are normally being used for pvc pipes (electrical) and they do a superb job holding the frame,well at least the last 600 miles I drove with it,just filed them down a bit for estethic reasons.
The screen pops right out of the clamps if you need it to,the friction is enough to keep it in at any speed,is adjustable in height,goes together with the tonneau cover and has enough clearance to close or open the top without removing it.
I must add that this used to be a screen for a 916 that I narrowed down to clear the seatbelts, the seat belt on the picture is out of the guide because of the photo's
The cloth that is on it can be bought at any good convertable specialist for as little as 25 dollars and is easy to replace.
Some pictures:

grtz,
Frans

My deflector (which is much to your design - frame covered in black plastic and a net) came with four brackets. I only used two of them fitting the deflector using an union on the hood frame.
It very easy to fit, hood goes over the deflector going up and down and the deflector can lay flat backwards both hood up or down.
