Oh Gawd. Moar pics plz. I'm not too familiar with handling CF so I'm amazed at how light it is. I saw a Motortrend or C&D article about the Aventador and how the prototype was 300 lbs lighter than the production model. They hypothesized that it was due to the prototype having a hand-laid carbon monocoque where as the production models were machine injected carbon. Is this how your fastback is so light?

Actually, that fastback is done by hand. I didn't infuse it. If I infused it, it would be lighter again. About 5lbs. I have a boot with an NA g.v lip spoiler that I had to cut to fit the NB boot. I plan on using that, or making my own - longer and lower.

I just finished the new package on my red car. The rear wing is now 2 element (dont think it needs triple element for phillip island). I have a new front splitter/undertray, new side skirts, and a new carbon fibre fastback. I am hoping to get into the 1:53's at the island. The only other mods i want to do is remove the restrictive muffler, and put a stright thru one on. And an enclosed pod filter, instead of the factory airbox.

Do you have any details on how you did the Gurney flap (lip) on the front heat extractor vent? I am looking at the doing the same thing and yours is the cleanest DIY I've seen.

I am going back on the 11th of nov, then I will be back on the 17th nov. Same track. The fast one. It is a really good track for aero testing. Should YouTube it one day. You are doing 160+km/h leaving the last corner, then go down a 1 km straight before you have to brake and turn into a 180+km/h turn 1. That is with no aero. YouTube Phillip island lightyear, I have a few videos.

We did the on road wool tuft test. Here is the video. It shows good laminar attatched flow over the fastback. Speed was 50mph. Brendan got a bit carried away with the descrition. I might have to change the title, etc.
