no spoiler look

[REMUS]

What do you reckon on this, most GTE's seem to have the spoilers still on. I think this is quite a nice style, what do you guys think?




The Rear bumper isnt really to my taste but I do like the tail gate and the custom vauxhall lettering on the smoothed area, although the pic's are quite fuzzy.

id like da whole car if da bumper at the bakc didnt stick out so much from the tailgate!!!!

but yeah no spiler looks nice, but it makes me think of a bog standard astra

my gte has no spoiler

yeah rear spoilers actually really screw aero-dynamics.

yeah rear spoilers actually really screw aero-dynamics.

for a good reason ! the mk2 is shaped like a big plane wing, the gte aerofoil "spoils" the airflow going over the back of the car to stop the rear end lifting at high speed !

i think i read somewhere that the only road going cars with big enough wings to create positive downforce are the sierra and escort cosworths. all the rest of the cars fitted with spoilers are there to prevent UPLIFT !

Well I know the physic's in the operation of a performance rear spoiler.

A GTE spoiler isnt located in an area where is recieve's enough of an influx of high velocity air current to create a downforce in comparison to say the roof tip spoiler that is available or even better the whale tail even if it looks kinda funneh

[DarrenH]

but it doesnt create downforce, i already said that !

[REMUS]

and therefore it doesnt do anything worth taking into consideration... my point was that the spoiler only has one effect which is drag.

Ran mine for a while without the spoiler, only difference i noticed was it didn't look as good as it does with it on

[dethstar]

apparently the air flow isn't fast enough for the spoiler to have any affect (if any at all), until you are doing at least 100.

[REMUS]

depends on the position, surface area and angle of the spoiler, some of the chav'ed up saxo's you see flapping around have pretty decent down force at 20 mph lol

There will be high speed air flow over the spoiler. It will flow down the back of the tailgate.

Anyway, the rear spoiler is what make a GTE look like a GTE.

[REMUS]

I'm afriad like all hatch backs this isnt true, the only air that reachs the spoiler is the disturbance created by the contours of the body steamline.

If you don't believe me all you need to do next time your at a rolling road when they set up the big fan, is stand behind the car. Nearly all the air is deflected away.

The GTE spoiler is purely cosmetic. I think the front and rear bumpers make a car look like a gte imo.

[tomstickland]

Nah, when the air flows over the top of car then it also flows back down the rear of the tailgate. There is a low pressure area behind the boot of the car sure. Lowering the drag coefficient is all about trying to make the front and the rear of the car streamlined so that the air flows above and below can match up.

[REMUS]

And thus my rather simple/blunt point "yeah rear spoilers actually really screw aero-dynamics."

A rear spoiler is not steamlined. A car will go faster without one.
