Default Lightyear Carbon fibre fastback street/track car

Hi, I thought I might start doing a build thread on my Black 2001 MX5. I bought it pretty much stock a few months ago. It was cheap, very cheap. It did have issues, like it hardly ran, and it had a very loud clunk noise from underneath. Body is a little rough, but overall not a bad car.
First thing I did was find the clunk sound, turns out it was the front Uni joint. So I replaced the whole tailshaft, and no more clunk. The next job was to see why it would hardly run. I cleaned all the leads and coil packs as they had a lot of oxidation, installed new plugs, and it ran perfect. Sometimes you get lucky.
I only had it for a few days when I was invited to a track day, so I quickly prepped the car with new brake pads, discs, braided lines, wheels and tyres, steering wheel and seat. I also had a carbon fibre hardtop lying around that I made a few weeks earlier. So I threw that on and removed the soft top.
It had some old coilovers already in it, but still had the open 3.6 diff. So with "new" 7 year old R specs and an open diff, I had little hope of a quick lap time. But it managed to do a sub 2:00 minute lap time at Phillip Island. I was happy enough with that. My best is a 1:50 with Oem N/A 1.8 motor aero, weight loss, etc, etc.
I just dropped it off to get a half cage welded in, and should get it back early next week. Seeing as it is going to be a permanent Lightyear fastback MX5, I had to take the car with the roof on so he can build the cage to suit. These fastbacks should be available to buy in a couple of months. New moulds are being made at the end of the month. But I won't be here as I am going to Sema. When I get back I will continue with them.




I will be making carbon fibre doors, hood, roof, trunk, etc for this car. And use it for car shows, track days, etc. It will get a little IHI mazdaspeed turbo kit. I have it lying around, so may as well use it. Along with an MS3.

Here is a video of a pre production fastback.

and another..

The sump is getting drilled and tapped for the oil return line today. ��
I have everything here to turbo it. And would expect to have it done in half a day drive in NA, drive out with double the HP.

I will be interested to see what price point you will be able to hit with the fastback.

I will be keeping the price as low as I possibly can. Seeing as it's a roof, trunk, hinges, brackets, Windows, rubbers, etc,etc. it all adds up unfortunately. It should still come in under $2000. When I get back from California, the new moulds will be made, and a fastback will be waiting for me to pick up.

Today my 7 year old helped me remove the Mazdaspeed gear I had on another car. So when it gets back from the shop that's doing the half cage, I will get stuck into swapping all the turbo gear in. Should only take a couple of nights.

It's cool enough. With 6.2l of V8 under the hood it tows well.
The rollbar and oil return have been done. And my 15x9 Storm S2 wheels have arrived.

It's more than enough for me. 4630 pounds. The trailer weighs 750 pounds, and the car on it weighs 2250 pounds.

Towing capacity doesn't matter when you drive upside down.

Will the fastbacks be made in Aus? Are you selling to US customers?
