What is that fitted to wozza? Looks one hell of a machine? Some kind of Ultima GTR at a guess?

That's looking to be the easiest option. Was just thinking about future if I want to make another I will have to figure out how to re-create them somehow. Baby steps first though :p
Looking on the easy composites site the regular unimold kit includes
Uni-Mould Tooling Gelcoat1kgUni-Mould Coupling Coat1kgUni-Mould Tooling Resin5kg80g Chopped Strand Mat2sqm450g Chopped Strand Mat2kgMEKP Catalyst200mlPlastic Finned Laminating Roller50mm WidthLaminating Brush2x 2"Nitrile Gloves10 pairs
I'm thinking this should be enough to do both halves.
Main issue here for me is location. While I would love to use the kit and support easy composites for the videos and help I'm not sure how economical it will be.
This kit is £80 and shipping to me would be an additional £97£177 = $236
With that being said, ill be hunting some US options for comparison. If its not cool to be talking prices let me know, I just like to have everything documented for others to reference later on.
Here is what I was able to find, I tried to locate items I think are a direct replacement. In this case I sourced all prices from us composites. I'm a Canadian living in the states, metric makes sense to me but have to do conversions so I could be off on amounts.
Uni-Mould Tooling Gelcoat 1kg - Orange tooling gel coat 1 Quart $ 22.50
Uni-Mould Coupling Coat 1kg - ???
Uni-Mould Tooling Resin 5kg - 404 Tooling Polyester Resin-Isophthalic 1 gallon $39
80g Chopped Strand Mat 2sqm - 3/4oz Chopped Strand Mat ~2sq yards $4.50
450g Chopped Strand Mat 2kg - 1-1/2oz Chopped Strand Mat ~5sq yards $13.75
MEKP Catalyst200ml - included with resins etc
Plastic Finned Laminating Roller 50mm Width - Fiberglass Detail Roller 2" $5.95
Laminating Brush 2x 2" - 2x Bristle Brushes Wood Handle $1.60
Nitrile Gloves10 pairs - Disposable Latex Exam Gloves (50) $10.00
The only thing I could not see a similar product for is the coupling coat. Is there something I should be able to find or is it a custom mixture? I figure its just resin but again I have no clue what I'm talking about. Is it maybe a vinyl estor resin?
With that and shipping I should save ~100 bucks so that would be nice. Thanks for the help/input as always

If you can afford to sacrifice the spoiler you have then I would use the Mounts off that. That way you know they are up to the job. Just lay up some extra layers of reinforcement around where the mounts will be.

wozza (19/02/2013)
This the Wing I manufacture, it can produce 258 kg of Downforce at 140 mph. The construction is 200grm 2/2 Twill, 190grm Plain Weave, 2mm Soric and 190grm Plain Weave. It is made in two halves (upper/lower) and bonded together. The mounts are eight layers of 200grm bonded together, left hand/right hand.Wow, that's on a whole other level right there. Very nice! Gives me confidence that the carbon should hold up just fine at my measly 80 pounds :p. I will have to think on how to do the brackets. I've not done any real metal work either (besides hack jobs) so I'm going to have some things to figure out either way. I suppose the first order of business will be the mould either way. Will start putting a supply list together. I basically need everything/anything that will need to be used. Thanks again guys, feeling good about this.

"Thanks for the help/suggestions all, this place is great! The spoiler produces 80 pounds of downforce in the back end once deployed. I am not sure how that translates to the forces that are placed on the spoiler itself. As far as adding to it, it would be primarily cosmetic (bout an inch lip or so) I would not really be increasing the angle or trying to purposefully add a lot more downforce. If it happened to make a little more It would just be a bonus side effect."
Uhm, that will put 40lbs per bracket. Not a lot, as you point out, but worth considering. You'll also get that same force spread evenly over the spoiler. Imagine 80lbs of sandbags stacked evenly along its length. That's the force you'd need to engineer for. I second the comments about using a core material for this. FYI, they work by increasing the thickness of the laminate and as a consequence adding a greater resistance to flexing. PS is the quote function on this forum broken?

Startech created a stick on part for the back, it would be a similar style design.Here is a shot of what it looks like deployed with the startech piece. This is another crossfire forum members ride, mine is black. And with it down
The little extra lip makes the back end a little more interesting. I was thinking of multiple sizes to try out if I can actually accomplish the task.
Thanks again for the input! I will take all the help I can get.

For a wing such as this if you are actually making it practical in a sense of actually making some downforce at some point i would definately look at something on the inside such as a hard styrofoam or ally honeycomb or more carbon even just to stop it from A) being bent/manipulated by the wind, B) also heavy-ish so that it dosnt just get blown off the mounts. Personally i would make metal brackets to attach them too. I had a go at making differant forms iof carbon bracket (U, 45 degree angles and such) and they all came out pants, and not strong enough for the job i intended them for, thus making me stick to metals.
