That'll add thousands to ya cars value for sure, very nice look.

Bahahahahahahahahahahahahahaha- hahahahahaha *takes a breath* hahahahahahahahahahahahahahaah- a
Is that auction serious! Really! What a bargain too lmao
"Significantly improves road safety in wet or dusty conditions by reducing the size of the cloud of spray or dust following in the wake" .it just gets better the further you read
No doubt, there will be at least one muppet that buys into that. as they say - a fool and his money are easily parted

Mitsubishi added them to the FQ series of the Evo. It does make a positive difference to the air flow over the rear of the car, preventing it from becoming as turbulent. Yes it will decrease drag slightly but their objective was to make the rear wing more effective by being in a smoother airflow.
Vortex generators on an aircraft are to move the separation point rearward and delay the stall, allowing the aircraft to stall at a higher angle of attack. Great for getting strip jumpers off the ground in short distances.
I dont think their fuel saving will be noticeable, I did consider putting them on the race car to help reduce drag but am in two minds about it still. They will be easy enough to make so might be worth the experiment.

Wow amazing that the car manufacturers haven't thought of it.
This shows their effect. Yes they work, Yes they will probably save fuel but No I dont think it will be significant.
More effective is closing up all the unnecessary vents at the front of the car, they cause about 10% of total drag and that was tested on an audi A2 I think it was, modern and sleek car from the factory.
It was to make the rear wing more effective, less drag was just a bonus

Those things on the Mitsi are a totally different shape.

Oh I don't doubt the concept works to some degree. But I simply can't see those "things" that are advertised making any difference (if any at all) that's beyond negligible. There are a LOT of claims with zero proof. and from a brand new user too. Are they even the right shape! Again, no evidence of any testing is provided. A wrong shape could even be detrimental to economy! The angle they're set on could also affect things. Lots of claims, massive price. no proof In my books, that equals a scam.

They may or may not work but look what they want for them. $150 for sweet F A lol

And he can work out the savings from how many km per 100km! Whne I went to school it was always 100

probably just folded alloy, about $5 worth of material haha.
The vortex generators used on aircraft are a similar style to those in the auction, but they are often split into separate tabs for the left and right angles rather than on the same tag.
I did think they looked metallic, but thought it might be just a grey plastic. If they are alloy, would that not make them illegal to fix to an on-road vehicle such as they are! Sharp edges and all that. Those look like they'd cut a bouncing pedestrian to bits.

Is that you Sheldon! Grab one of Peter Brock's fuel polarisers for the race car too, couldn't hurt ;)

oh ffs, Im going to take the bait. This product is genuine, but the claims that the seller promises are not. A vortex generator on a light aircraft can reduce stalling speed by around 15 knots, that is hugely significant.
Read my link, mitsi claim 0.006 reduction in Cd, which although seems a small number, is really about 2% decrease in drag, and it also mentions that lift is decrease by approximately the same value which is good for sticking to the road.
For once one of these products has science working for it, but the marketers are getting a bit over-zealous with their promises. After reading that mitsi document I do definitely want to try them on the race car because a 2% decrease in drag may mean for me an extra 3-4km/h at the end of the straight, and when you don't have power to play with, being slippery is very important.

Agreed. On the face of whats been presented, it looks correct in principal. Total effect is a different matter & what that Trader is presenting as fact, is very likely grossly exaggerated

It's probably a bit like what I have just done with my Surf. I have swapped my factory steel rims for alloy mags. Yes, good. The Surf "feels" different but I can't define what "IT" is yet. You ask.whats the difference in the wheels! Thats easy to answer, those alloy rimes are 6kg lighter then the std factory rims Approx weights are . Factory rims = 13.2kg Alloy rims = 7kg
Now . for what the driver will notice about those gadgets, is probably about the same as I am noticing about the different rims. hard to define, but it IS there.
