Has anybody made one or has one fitted
It fits under the back of the car and has fins to direct airflow.
I have seen one fitted to an MK but i cannot remember where
I think Hellfire has a diffuser on their MK
ive got plans to make one for my striker but its a way down the upgrades list at the moment.m.
dont you have to have a completely flat floor (inc engine bay) for it to do much? most (but not all) cars on here will have the engine below the chassis rails I'd guess.
i have one fitted to the back of my rush

Hellfire have one fitted I believe
Steve Keenan had one fitted to his Indy at Oulton park last weekend.

Here's a pic of Danny's at Oulton last week!
I thought I had a better pic than this, but maybe not!

I've made one up out of aluminium sheet - not difficult but can be fiddly. See :- http://www.locostbuilders.co.uk/viewthread.php?tid=82829
It's now so efficient on the highway that I have to turn the engine off - otherwise it just gets away from me!! In truth, running it with a
front undertray as well certainly smooths the airflow under the car - but any differences in "feel" seem to be very subtle
Who cares if it does anything, it looks very cool. That's enough for most of us.

Hi
It has to be said though that a majority of the ones fitted and sold do nothing at all and actualy slow the car down.
It would seem that the Kitcar scene is slowly becoming like the boy racers scene where it doesnt matter as long as it's got enough BS to go with
it. 
Cheers Matt
what about on a fisher fury, do these things work ?.
Made a couple of these....
Marc at MNR is making one specifically for the VortX. Ordered mine when I placed my order. According to Marc's last post on it it should be ready
around now (but may be delayed while they put up their new workshop building).

im on with making one at the mo but havent got any pics just yet. remember not to leave any sharp edges if you havent passed SVA yet.
Please explain how on earth blocking a great big space, under the car slows it down? Obviously, that space is creating drag by reducing the flow of
air. All we want is an increase in smooth airflow.
I have a background in aviation and know full well the implications of lift (or downforce) vs. drag, angles of attack etc. so that argument is not
valid here. We know that there is no downforce without corresponding drag. We are not talking about large wings.
But to be accused of being a boy racer? Sure, whatever. Better than being an old racer.
This might be more effective....

Hi
As Rob has said the way in which most are attached and the angles that most get mounted at and the fact that most have not panneled the other areas on
the floor of the car. Means they do nothing for actual performance. I shall not try to tread on Robs Toes in the Aero department and actual wind
tunnel testing. But in actual driving 7 type cars round circuits at speeds up to around 135 mph. What you start to find out is that when adding such
things as diffusers rear wings front splitters is that in a majority of cases they do little to increase actual performance / handling but do take a
significant amount of speed off the car. For instance on this pic below the rear spoiler dropped the speed by a whole 6 mph whith no noticeable gain
in handling etc.

And although the front spoiler did add a little grip at the front on the fast corners it also took a significant chunk of speed off the car hence the
prototype snout to try and do somthing to regain some of the speed.

All in all if diffusers etc are done with some research and thought they can be of benefit. But the majority of them fitted are doing nothing for
actual performance gains and in some cases will actualy be a deficit to performance. But on a road car at road speeds they are fitted purely for there
looks.
