My Fastbacks have gone into production. It's a great piece to Miata aero efficiency. Lowers drag, allows perfect airflow to an airfoil so the laminar flow is undisturbed unlike a hardtop, or worse, no roof. Lowers the cod as it removes over 48lbs from high up on the car. Changes the look of the car for the better. And it's also weather proof. What more could you want?
And priced from $990 US plus shipping. Full kit is $1400 US.

I haven't tried too hard to get a good price on shipping. But the one quote I got was over half the price of a 20' container. So if I did a bulk ship in a container it would work out very cheap. If I sent a container to LA, and gave the dimensions of the shipping box, you can work out the shipping costs from there to your town. A container was about $2300, and a single box with pack and send was around $1400. I will get a couple of quotes from other places. Or if anyone has the time, and wants to try, I will give the dimensions.

And the splitter point just worked out that way. The plywood add ons are strips around a foot or less wide. See the straight edge that comes from the point on each side? Once on I was going to make the curve, but liked the point too much. 
It pierces the air as it breaks the sound barrier.

Sorry for the thread drift. Very hyped on this.

I didn't take a pic when I made the NA trunk. But this is my NA with a fastback roof sitting on it. This NA deserves to be in the forum. It's a fully built motor and proper turbo. And will have a huge dual element wing I am making.

I have not worked out how many would fit, but it would be a lot. The size is about 145x135x45cm from memory for the shipping box. But that's just my memory, could be different. I have the dimensions written down.

Well traditional uprights are not the best for downforce. I wouldn't do it unless it was in the rules. I do make wings, and this is an early non moulded wing I made with a vac bag and foam core. I have a proper dual element wing mould now. It's an SM183. The width on this wing is narrower than I would like as I was running an eBay wing originally, so made the uprights/endplates to suit. You can buy this set up when I make the new one 
It works well. I still hold the record for the fastest MX5 outright at the fastest track in Australia with this aero package. And that was in a basic road car with Oem Mazdaspeed turbo, manifold and downpipe running 225 R specs. Minimum speed at turn one was almost 130 mph. You can check out the video on my YouTube channel. LightyearMx5. It was around 2 years ago now.

There have been a few offers to help with shipping and distribution, so hopefully something works out before too long.
And since this is an aero thread, here is my dodgy front splitter/airdam. It's alcubond with plywood added to increase the area. Box alloy frame supported front, centre and rear. I found that at very high speed the undertray will get pulled down if it's not supported well or strong enough. A sheet of alcubond unsupported looked like a bowl after one session. There must be some real forces going on under the car.
