When you make your moulds, how many layers of FG do you use? Also, what's the green stuff on the mould - is that the gel coat for better releasing of the CF? Going back and finding more info

When you make a mold you first brush on a couple of coats of tooling resin, then as many layers as you can of fg. Till it is at least 5 layers thick. The more layers, the stronger the mold will be.

A friend gave me a set of digital fish type scales to weigh my parts. I tried it on the hood, and it weighs 6.8lbs with the frame on before trimming. I will be trimming both the hoods in the morning, and see the final weight.

Engine mounts arrived today-


I weighed the hood finished 6.2lbs, and the doors finished weigh 4.0lbs. That order is finished, and all the panels are in my ute/truck ready to take down to be packaged for shipping.

Just sand them. If you clearcoat the parts,the edge gets sealed.

I went to the local track that i crashed the silver nb at with the crap tires. This is a video comparison of the old kumhos vs the new nittos. The nittos are a very good tire, can't believe the grip. I set a new class record by almost 4 seconds and beat every under 2l car out of a field of over 40.

I am going to make a fastback like autokonexions, but with the look and function i want.

I was at the local track today, and in between sessions i designed the window shapes. The rear window will have square corners at the bottom edge. What do you guys think??





I wanted to get some data to show any improvement with a fastback, but the weather didnt want to play the game.

Man that looks so freakin awesome..... I have been gearing up for a Autokonexion fastback roof but now I am intrigued to try and make one like you (one day). I just finshished painting the roll bar and slowly putting things back together.

How thick is that sign material you used, I got some for an undertray but I think mine is the thicker version, might be too hard to try and shape...

I like that. But I doubt you would be interested in making them for others

And the material is 3mm i think.

Holy crap, what a build thread!

I am thoroughly in awe, keep up the amazing work man!

What durometer did you get on those motor mounts? I was so close to getting the lowest duro ones a few months back but I chickened out and got Mazda Comp ones instead since I was afraid the poly would be too much.

I particularly love that fast back version you made over the autokonexion's.

They are the hardest durometer. I don't want any movement due to the intercooler having basically no pipe work.
I prefer the fastback to have a more incorporated side window. The others look like a porthole in the side. I think that is what makes it look better.

And I was only 1 sec of my best time in this car on Sunday. And that is with the track drying, but very slippery on the last corner, meaning you couldn't get the power down to get a good run onto the straight. Plus turn 2 was slippery. On a fully dry track, It would have gone quicker.

Vid of me chasing a worked lotus elise on sunday.


The memory card ran out, so didnt get the whole session. Pity, as it was an awesome battle with some very close "racing", especially under brakes at the end of the back straight going down the hill into the left corner.
