Rear Dust Deflector

[Chrisnussey]

Has anyone found an option to fit on the rear? I'm sick of the dust pile on the sill of the upper tailgate.

[Graeme]

I'm looking to replace my D4 with a late L322 but don't look forward to not having the rear kept clear of dust that the D4 does so well. I wouldn't like to return to the days of my 1st D2 that didn't have a dust deflector but worse due to the L322's split tailgate.

[CSBrisie]

Limited market I guess Chris, not many of us get them off road enough to get dusty - let alone cross the Simpson desert!:p

[Chrisnussey]

Looks like the old original universal alloy version it is then.

[CSBrisie]

Yep, I googled and checked UK etc etc - nothing. :(

[Graeme]

Perhaps there's an acrylic one for another vehicle that could be close enough or made to fit, eg the Pathfinder's.

[Graeme]

I'll have to find one from another vehicle because the back of mine gets totally covered in mud drawn-up from below when driving through slops and on wet unsealed roads. I had also previously spotted dust swirling around the top of the window.

Graeme, please keep me in the loop over this as I had that nice little layer of very fine silt that comes thru the tailgate on our cars after my recent trip away in the New England. Got the same thing with red dust in WA when I took the car over there. Gotta stop it somehow!

This is why I want a dust deflector - the D4 was never like this.

Mine looked like that in the New England as well. I had to keep washing the back with a hose when we got back to the lodge so I could open the tailgate and not fill the car with bull dust! Whilst that looks like crap, the worst part is what sits in the shut line gaps.........they just fill up and then shower the inside with a light coating of dust every time you open the rear end.......got very peeved with it whilst away this time. you can see it a little bit in the attached pic.

[Graeme]

How similar are the 02-09 rear spoilers to the 10-12? There is a part number for each of these model ranges so knowing if the difference is significant or not regarding shape would be of benefit if a single design dust deflector would fit all L322s. Do MY10-12 use a LED stop light whereas the earlier ones use incandescent? If so then the difference may only be the mounting for the light. The pictures in the parts catalogue look identical but they are only line drawings.

[Graeme]

Being utterly sick of dust going everywhere when the upper tailgate is opened, I had a fiddle trying to raise the spoiler so that it could catch air. It could be done with Z brackets to raise and move rearwards the leading edge and something similar for the rear locating grommets but concluded that it still would not intercept enough air to keep the dust off the window. I must get to an auto accessory outlet to look for a suitable deflector from some other vehicle - perhaps a task for next week.

[Graeme]

I've only had one half-hearted attempt to find a deflector from another vehicle so far but had to take action to prevent total loss of paint from the top corners of the lower tailgate where the seal on the top section was using dust to grind away the paint. The top corners of the lower tailgate are now covered with protective plastic film that is almost invisible but doing its job. My D4's whole top of its lower tailgate had been covered with film after a respray when the paint had worn away.

[p38arover]

I'm interested, too. I noticed the dust after a recent trip. I'm sure my P38A didn't get as much dust on it.

Graeme, I'd be interested in a pic showing the location of the clear film.

Maybe we need the defectors used on cars in the Sixties! :D

I did see an my12 shaped Autobiography L322 in Brisbane with an added section to the roof. It looked like a sun visor for the rear window but could have been to keep dust off. This looks like it

[Graeme]

Overfinch have an extra spoiler for the L405 but it looks more like one that provides a little down force at speed rather than a wind deflector for dust control but perhaps they also had one for the L322. My MY12 AB only has the standard spoiler which seems to cause dust to gather rather then keep it away.

I'll post a picture of the film tomorrow after I clean off the dust.

[rar110]

Does this look any good.

[Graeme]

Good find, but this QP Online version looks like a poor copy of the Overfinch version shown below. I note that the selling business has a picture of a vehicle fitted with an Overfinch one on their web-site. The Overfinch one looks to sit above the roof-line just enough. An inquiry to Overfinch has been made but they are closed until 11th.

https://www.aulro.com/afvb/images/imported/2016/01/878.jpg

The QP Online version appears to have a convex shape to catch the air whereas I would expect it to be concave in order to direct air downwards. It doesn't have the curved-down edges of the Overfinch and appears to be narrower.

[Graeme]

I think I'll buy one of these...delivery quote when they open on 6th. If it doesn't catch enough air then I'll fit a spacer under its mount.

Roof spoiler LAND ROVER Range Rover Mk3 L322 , only for Vogue (http://unqshop.com/land-rover-range-rover-roof-spoiler-vogue-,f,11,number,480168)

[p38arover]

But will it work as a dust deflector?

[Graeme]

It only has to direct some air down to reduce the lower pressure that causes the dusty air to rise. As it mounts in the stop-light mount, its height and angle could be adjusted although much of a change in angle would make the ends curl upwards and look strange. For 69 GBP plus postage (hopefully not to much) I'll give it a try.

Edit: Ouch! 99 GBP delivery. It might not be much more for 2 or 3 but then would need to distribute the other(s).

[p38arover]

And then you have to paint it. Why do they say Vogue only?

The problem is also finding something that looks OK.

It probably wouldn't be hard to make something that looks reasonable and could be fitted for trips. Perhaps a couple of fibreglass mouldings that fit each side and direct air down and diagonally across the window.

Vogue as opposed to RR Sport

[Graeme]

It also appears that "Vogue" is synonymous with L322s rather than P38s or L405s and even though lots of L322s didn't wear a Vogue badge, including mine that I refer to as a RRV.

[p38arover]

If one fits a deflector, I wonder what the effect of a loaded roof rack might be?

[Graeme]

Probably upset the airflow so that it no longer works!

[Graeme]

Here's the clear film. Perhaps better if not so wide to avoid the raised section although I wanted protection along the bottom for a little further. The cover strip was removed during fitment.

[Blade74]

Mine doesn't have film but you can see the start of wear marks. Maybe I should use some film.

[Graeme]

Below are top and underneath pictures of a JSP spoiler sold in the USA that appears to be identical to the Overfinch one. The top has a rounded leading lip that looks to send air over the top and the underneath is flat. Hence I suspect that its not going to divert air to have any effect on dust-filled rising air even if angled up at the front / down at the rear.

JSP have been made aware of the desire to have a deflector for dust reduction and have been asked to what extent their spoiler might be useful for this purpose.

It was from the PowerfulUK site to show tail pipe ends I think.

There was this design which might have better design qualities.

It was from the below site.

[Graeme]

Your picture and link are Overfinch which look identical to my close-ups - no good for redirecting air downwards.

Edit: I found the rear spoiler pic on PowerfulUK and another there showing 2 RRs back to back, with one having a very dirty rear window.

[p38arover]

one having a very dirty rear window.

Which one? :angel:

[Graeme]

https://www.aulro.com/afvb/images/imported/2016/01/835.jpg

However the clean one is also clean behind the rear wheels so hasn't seen dirt or road grime since it was washed. The other one is typical - clean everywhere except the tailgate and a little dirt behind the rear wheels.

[rar110]

Here's another, slightly different to your last pic.

[Graeme]

That one looks to be the Overfinch/JSP version.

I hope to hear back from PowerfulUK when they re-open to find out if the round-ended one is theirs and whether it deflects air downwards or not. My contact with JSP did not elicit any comments regarding their spoiler's ability to deflect air downwards.

[Graeme]

The PowerfulUK version was a prototype that wont be produced, instead soon to produce one very similar to the Overfinch version. It wont be a deflector for dust reduction.

[p38arover]

My lower tailgate has the same wear patterns as others here. I think I'll add the clear film.

[Graeme]

The metallic gloss on mine had already gone so I thought it would not be long before bare metal was showing, as happened with my quite new D4.

Interesting comparison Jerry. I wouldn't have thought the LC design would have directed any air south. It clearly does.

[Graeme]

The LC's works because it catches air on its leading edge and directs it down below the spoiler through the big gap between the roof edge and the spoiler, not above. All the L322 add-on spoilers are designed to send the air over the top.

The drawback of a centre-stoplight mounted L322 dust deflector spoiler would be that the centre would be blocked from directing air and therefore its unlikely to direct enough air to keep the area under the stop-light clean. A clip-on acrylic purpose-designed deflector as made for various other vehicles would be ideal.

Here's what the LC200 looks like underneath..

[Graeme]

PowerfulUK have advised that they will consider my request for a dust deflector version when designing their new spoiler, but no promises.
A follow-up inquiry to PowerfulUK a couple of days ago has prompted a request for pictures of dust deflector spoilers, which is the most encouraging response yet to any of my inquiries. The current LC200 deflector/spoiler was provided as an example.

I trialled moving the OE spoiler rearwards and tilted up at the front to direct air beneath it. Existing dust was totally removed at speed on bitumen but still accumulated enough on the ledge at slow speed to deem it not worthwhile, especially as the spoiler gave the appearance of falling off. A deflector wing mounted in the upper stop-light position is unlikely to keep the window totally clear but would hopefully at least keep the ends clear enough to prevent dust falling inside when opened.

If PowerfulUK don't proceed with a deflector spoiler then I'm likely to purchase the cheapest spoiler and fit horizontal perspex or similar panels on top of the forward edges of its wings unless I find a Pathfinder with an acrylic one fitted that looks like it could be made to fit.

[Graeme]

PowerfulUK have sent their design for a rear spoiler incorporating a dust deflector to the model makers.

[Road Stone]

Hi,


Thought I'd put another piccie of dust. This one after 17klms off road.

Dust sealing is excellent, virtually nothing came in.


Cheers, Jerry

[Graeme]

PowerfulUK have scrapped their 2nd attempt at a rear spoiler that included an attempt at a dust deflector in favour of a design similar to the L405 spoiler. They didn't state if they would still attempt to include a dust deflector capability.

I am not surprised they gave up. The spoiler on my L405 is no better than my previous L322. Gets plenty of dust on rear window and the more complex shape of the body surrounding the rear tailgate makes cleaning a lot harder. No dust inside yet, however only short trips on dirt so far.

[rar110]

I wonder if a vertical spoiler attached to each rear pillar would work? Very 70s. It wouldn't be hard to make them from alloy.

[Graeme]

Vertical scoops/deflectors home-made from carbon fibre fitted to the sides of a particular L494 seem to work quite well and don't look obvious either.

[Graeme]

I suspect the L405 style is only to make the L322 look more modern, not in an attempt to deflect dust better. I also think they would have to be considering replacing the existing spoiler rather than mounting in place of the top stop-light.

Any pics?

[Graeme]

I thought I had a pic but it's eluding me atm.

[Graeme]

I'm thinking again of getting the 69 GBP spoiler below. I think that the combination of ensuring that its mounted high enough to catch air and by adding a layer underneath the front that it stands a good chance of working. Unqshop's freight cost has come down from 99 to 59 GBP so that helps. If I get one then I'll first try it without modification.

[Road Stone]

Hi Graeme,


Did you go a-head with this?


Cheers

[Graeme]

No I didn't because when I was confirming the order the freight cost jumped back up to the same that I baulked at late last year. The price given on an on-line chat session wasn't upheld. I'm still pondering my next step but am really sick of the dust/mud on the window and hip.

[Graeme]

Having spotted the large slots in the top and underneath of the D5's spoiler, I have procured a used spoiler from an earlier L322 at a good enough price to warrant a test of similar holes. Whilst the airflow wont be as direct through the spoiler as the D5's, hopefully it will be sufficient to cause a worthwhile reduction in accumulated dust.

[Graeme]

Large slots in the spoiler keep the dust pretty much down at 80-90 kph on my lane but failed to make much difference at 50 kph on my 2km driveway, both made extra dusty by many semi-loads of grain over the last several days, although stopping to open a gate allowed the dust to catch-up and smother the back of the RR making it worse than when driving. I'll trial it for a while but suspect that some low scoops will be required to catch the air.

G'day Graeme,

How did this end up going? It has been some time now, did the scoops end up improving the dust deflection?
Pictures would be good if you can.
Cheers
John

[Graeme]

The scoops were very low so didn't catch enough air to make enough of a difference.

I have recently cut a 3rd, centre slot and have today acquired a low, dark-tinted sun-roof wind deflector that will be attached facing forwards. My 2 original slots are too wide for the deflector so will be filled in to the width of the deflector. The deflector sits within the lower section of the spoiler so is not much higher than the spoiler ends. I think it will look OK, much like a vehicle-specific dust deflector except that it isn't full width. If it tests OK then I'll paint my test spoiler black which will probably go unnoticed on my Bournville (dark metallic brown) vehicle although the dark tint might be acceptable on any colour vehicle. I'll post pictures when I've tested it.

Here is a link to the deflector.

95cm wide may have been better but the wider 105cm version would sit up on the raised ends so is unsuitable.

[Graeme]

Cautiously testing the new deflector: 100 kph into a strong headwind without it flying off and the dust keeping low then 100 kph with strong tailwind saw a little dust swirling on the windy corner, all without any noise. I'll probably fit a brace in the centre to help keep it tied down at higher speeds.

142998142999143000143001143002

The leading edge of the deflector needed to be trimmed by about 25 mm because it fouled the roof when the tailgate was opened. Mounting it further back wasn't really an option as it would have overlapped the stoplight preventing removal of the stoplight and because I wanted to fit clips over the front of the spoiler. Besides, it was already stuck to the spoiler.
The rear edges of the 2 outer openings could be sloped to align with the centre opening to gain a little more airflow.

[rar110]

Graeme,
Do you think this would fit/work?

[Graeme]

Those are half the width of the deflector that I used but something that could be hung over the back edge like it would be my preferred design.

[RSW Vogue 2004]

G'day Graeme,
That's looking the goods, now does it do the job at low speed as well? I'm taking it that you had some of that strong wind out your way yesterday as well. Maybe today will be a little better for a test run.

On another note, have you sent my dual battery set up yet? If not I would like to have the Anderson Plug attachment as well.

Cheers

[Graeme]

I'll try again tomorrow although having had 4 mm of rain last night the dust wont be very indicative.

You probably should be talking to Drivesafe about your dual battery kit.

[RSW Vogue 2004]

Probably not much dust around your place at the moment then.

Yes, crossed wires on that one, thanks, I'll get onto him .

I couldn't see how an 80 Series version could be mounted and the GU Patrol's is too wide. A universal one quite probably could be mounted and work well too but I didn't like the thought of one on the RR, perhaps reminding me too much of a similar one on my father's Morris Marshall wagon many years ago.

This one by Startech looks good but was part of a very expensive body kit and IIRC isn't available anymore.
