Gerrelt - surely on the front the Kamei does the job of this?

Yes, you are right. That's why I want to create a set for the rear.. :)

:) Just checking that I wasn't missing something!

Is it worth it going to flat taillights?

Possibly if you want it to look hideous... They ain't for me regardless of what they do!

I guess I asked the wrong question, I don't care about the style, etc. but along the lines of:

Does the taper of the taillights rolling off the back of the fender make an area of dead air? Would smoothing this out to follow the contour of the rear fenders be better for flow/drag or would it not matter? Plus it looks like the flat ones are a little bit lighter than the stock ones.

I think it doesn't matter anything. The rear lights are probably allready in a turbulent or low pressure area.

I don't like the look of the new beetle style rear lights.

I've grown quite fond of the elefants feet rear taillights. They have a really nice functional look.
I only wished they were a bit better build.

+1 'Scheisskwalität'...
I have one taillight reflector housing that has two seperate departments and is a cast/mold alu-like material and very nice quality. Never could find another one though...:(

+1 al kaholic...
I don't like the look of the new beetle style rear lights either. :rolleyes:

Ah, thanx for posting that. I never new there was a "metal" version of these lights.

I think they are from the late model VW thing (181).

Do they look like this?: Link to samba add

The Thing got them in metal for sturdiness for going off-road, is my theory..

I want a set! :D

Hi very interesting thread here.I would like some peoples views on the best way to dissperse air out under the car once its been through the front grill and through the rads.I do have a box section made up to cover the rads but I am sure that this could be better designed to creat downforce instead of lift and also channel air better under the floorpan.I have also been tinkering with some designs for the rear wings, apron and bumper set up I will post some sketches when I get time thanks.

Thanks for the link Gerrelt!.Think they are those.
Mystery solved!

Nice car Graham! I like some more ideas for backside front fender vents. I think you could make them so that the escaping 'high pressure' air adds a little in downforce.

Nice car. I think dispersing the air under the car from the front grill may create more lift by making a pocket of more air between the car and the road as you're trying to minimize the amount of air passing under the car. Sending the air up and over the hood through a scoop about 1/3 way up has been proved to create more downforce on the front end as seen on this Acura here:

...although I don't think you'd want to cut up that beautiful black hood of yours though?? Looks like your car is pretty sleek as it is. You could maybe install ducts from the grill to the backing plates of the front brakes to keep them cool. What kind of front bumper is that?

the aim is to get the air to flow quickly under the car, thus reduceing its presure. so as flat, leval and clean a underside as you can get will help. also deeper running boards to stop the air under the car spilling out at the sides.
the other option is to stop as much air as possable getting under the car but this can cause a lot of turbolance at the rear of the car creating a lot of drag.

Thanks for that Wally it means a lot coming from someone who owns a car like yours.:notworthy:

I will try and upload some pics of my sketches to show the ideas
