"*Aftermarket* sunroof" - words that seem to invite derision and
horror!

But I had an a/m sunroof many (many!!!) years ago and it never leaked
(10 years plus), wasn't used to break in, and it was marvellous - let
the heat out when parked in sun, gives wonderful open feeling to
driving, nice breezes, better air flow.

I don't want anything sophisticated, just a tilt/removable glass one.
Scary thought to do this to a brand new car, but it has a 3 year
warranty from the maker (Hollandia/Webasto), and... I really want
one.  There's no way I would pay the price of a factory fitted
electric monstrosity - I'm already offended by having to accept
electric windows & mirrors.

Any comments?  Feel free to insult my level of common sense!

If you want one, buy one. 3 Year warrentee? Is that including fitting? If it
comes with a fittment warrentee go for it. If your in FNQld get a blackened
out one, if your in Hobart, get a big one.  These days you should be able to
get a decent unit with good bonding glues etc.

So, you know the pros and cons, what ya gunna do?

Angle Grinder
cuting disk and flap disc
Broken Measure tape
Black window flex
screw driver
file
drill and bits
dusty back lawn

Lets fit it.
rain tomorrow night,we'll will do it in the mourning.

Whatr I can say is depending on what type of car and the strengh of the
roof metal,it could be very flimbsy and dodgy if a new car.
Thin sheet metal and lack of roof bracing beams could run a real issue.
Its advice.
That dose not mean somone charging $80 an hour can fit it and it look
and appear to work fine....

Why's that?

Every Ford, Holden or Mitsubishi made in Australia and sold with a "factory
fitted" sunroof has an after market one :)

Good point - and I think they are made by the same company...  But
there seem to be a fair few posts against them, and a number of folk I
have told about the idea have expressed deep concerns.  Guess I'll
just have to take'm for a drive on a nice hot day (or at night -
driving under the stars is cool, too..) and show them why I got
one...  And then in five years, take them again for a drive in the
rain.  (O:

Just to clarify, there is no way I would do this myself - authorised/
certified fitter only.

Website for Hollandia/Webasto is here if anyone interested.  No prices
though...?

I don't know why anyone would have anything against them to be honest, as
they're no more elaborate or problematic than power windows. In fact they're
usually a little better than power windows in that most have an emergency
manually operated means of closing the things if they stop working.

In all honesty they're not overly complicated to fit, and if you watched the
guys doing it you'd be quite amazed at the process :)

I've had a few, and if I had the choice I'd rather have one than not.
Whenever I owned a car with one I used it every single time I got in the
thing, and found them to be excellent devices. The only disadvantage is that
in having one fitted you lose around 40mm of head clearance depending on the
car, so if you sit in your car with your hair rubbing against the head
lining now then it may be a problem.

Figure on a couple of grand fitted for a good dual mode one.

All the Hollandia ones we have ever had fitted or were fitted factory have
been excellent.

Yep.  My mate got one fitted to his BA XR8 ute and it was done the same place
the dealers get them done.  Hollandia iirc.  It looks like it rolled out of the
factory with it.  Great job and no problems with it in the last year.

I think Holden actually does build Commodores with sunroofs 'on the
line' now - I'll have to check though.

I don't like sunroofs and wouldn't have a car that had one, every time I
drove my son's Prelude the first thing I did was make sure the stupid
sunroof was fully closed.
How anyone can put up the the wind noise and buffeting is beyond me.
What sort of car are you thinking about vandalizing?

Alt.baldspot ? :-)

Seriously, nope, don't want sun/moon roof stuff.

I can lay full length in the back of my pickup
and gaze at the stars and trees if I wanna (prolly
not legal, however have done at over 100 kph).

I don't like them either and would never have one. Just personal preference,
not because there is anything wrong with sunroofs perse.

If you actually want an argument against them: They are a big hole cut
in a structural member of the car.

Either your car is now much less stiff and crash resistant than before,
OR they've added enough reinforcing, which means the car is now heavier,
with a higher centre of gravity.

On a cruiser? Who cares. On a performance car? Going backwards.

Roof panels aren't structural members of car bodies, and any car maker that
claims they are should be on your "products to avoid at all costs"
shortlist.

They generally don't add anything other than the necessary bracketry to fit
the sunroof, which in most cases is bonded to the underside of the roof
panel.

All up weight difference might be 15kg at worst, and it that made any
measurable difference to a car's handling or safety you'd see roof racks
banned tomorrow.

The windscreen and roof are structural, however when the hole is cut
generally isn't unless they cut out the support brace (and I doubt they
would).

Roof sheetmetal is never a structural part of any car. The underlying
framework usually is though.

Yes, that's right. Sorry if I didn't convey that too well in my post.

The roof _frame_ is certainly structural, and in a lot of cars the
perimeter of the roof is structural in so far as it effectively
gussets the corners of the frame.  The reality is that you could
cut the middle of the roof out with essentially no structural effect
as long as the hole you cut is rounded at the corners and isn't too
close to the edges...

And before someone says that the cross-braces in the middle of the
roof are structural, I'll mention that they are *anti-drumming* ribs
that are intended to stop the large sheetmetal area of the roof skin
from behaving like a wobbleboard as the vehicle drives down the road.

and if they were structural, they wouldn't be offering the cars with a
"factory" sunroof
but then, anything to sell cars

So which bit is the actual structural roof 'frame' that you
mentioned?  I always thought the cross-braces were part of the roof
structure - certainly at least the one linking the B pillars.

The structural bits are the pillars, and the outer "square" frame section
that goes around the periphery of the roof tying them all together. The roof
"skin" is just decorative, and as Athol said the cross-members mainly exist
to stop the skin from deforming and drumming. It's basically like a car
door. The outer skin serves very little purpose other than to make the car
look fancy and keep the weather out, while the frame it's attached to serves
as the structural member.

That's the general case, but there are the odd exception to the rule here
and there.

Ever looked at how small those ribs are?  On some cars such as older
holdens, the one between the B pillars is bigger than the rest - it
is where the interior light mounts!  On the older stretched cloth
hoodlinings, the ribs are also used to hold the hoodlining bows in
place (the bows are inserted through the hoodlining to give it shape).

Try looking at a Suzuki Hatch.  They skipped fitting the ribs and just
stuck a piece of wetsuit style foam backed trim on the inside of the
roof skin.

The roof frame is a perimeter frame consisting of the section across
the top of the windscreen, the side rails and the section across the
top of the rear window (or tailgate on wagons, hatches, etc).  That
perimeter frame ties to all of the structural pillars.

You either love them or hate them and I'm the later:-)
I just don't see the point of the things, too much of a compromise to be
useful, they are a poor substitute for real soft top and IMO ruin the
look of a any car.

Depends totally on the "look" in my opinion.

I'm totally against the "el cheapo" flip up glass types that cost a couple
hundred bucks as they look like absolute sh.t. However some of the more
expensive jobs look good, and those that have a sheetmetal top like a lot of
the Euro cars do are hard to pick from a standard roof from a distance.

What I like about them is that they let in a shitload of air & sun on a good
day without having to endure the problems normally associated with true
convertibles, like leaks and cold during winter, and shitful rear vision out
of the faded plastic rear window.

I drove a somewhat bomby old 4 runner in the US, and was giving a yank
friend a ride one day, and she started pressing buttons... the hard roof
slid away! Revealing a clear roof. And that could be made to slide away too.
Bloody fancy, and it was a standard boring release old 4 Runner.

Thing is, you tend not to notice the sunroof when driving (I rarely open
Vitey's, there's no point). but the sunroof on the Toyota was handy for
sticking my hand out of with the camera to take photos without stopping.

Urk no. Nor a moonroof either.
Catherine Jemma - 22 Jun 2007 05:29 GMT
Back in about 1985 I had one fitted

My car at the time was an immaculate as new condition green Skoda 1100 cc
approx 1977 vintage

Back in NZ, especially at that time, refridgerant airconditiong was found on
very few cars, yet often you'd get warm wet rainy days and usually it was
impossible for the normal heater-demister to keep the windows  of cars clear
of misting-up

SUN ROOF whooooh fantastic.  Just pop the tilting glass open to the first or
2nd click (could still drive in anything except belting rain with it so
opened) and the heater-demister worked soooo much better, kept windows
clear.

If the weather was anything like reasonable, I'd pop out the removable pins
and remove the glass entirely. With a wee bit of practice I got used to
doing this in about 5 seconds flat while sitting in the car with just a
couple of movements, and mostly in one hand, then reaching far enough to be
able to place the glass roof-plate gently on the back seat behind me

From the inside the glass looked very darkly tinted, but from the outside it
looked mirrored

Never got too much sun in the car (in Aust some kind of shutter or curtain'd
be nice)

Never leaked during torrential rain

Car often parked outside including frosts

Sunroof didn't take up any more headroom that a thin metal surround, just a
couple of mm thick

I remember at the time, the total price was about $300.  At the time, the
cost of just buying the sunroof itself at an auto parts store (and fitting
it yourself) was about $150

I can't remember whether I looked in the yellow pages or just went to a
motor-trimmer sorta place I saw located while driving along the road in
suburban Christchurch, but I's very happy with the installation service

I wish I still had that car, my mostly country use averaged 37 mpg !
Excellent grip on dirt etc with the motor weight over the rear driving
wheels and even the old fashioned worm peg steering was as light as power
steering !  Had a towbar, it even towed a car-transporter trailer ok (empty
! I wouldn't expect it to tow one with a car on ! )
