      I bolted the inner half of the carbon fibre doors on and took a quick video. There will be a few hours getting them finished with windows, frames, etc.

        I made a window frame and door "handles" for each door. You might need to zoom in to see the "handle". I will make a large ~50mm hole in the window so it can be used from the outside as well.

          After reading about your carbon stuff you make, I'm keen to start doing something like this to my ND
          No Power chips thanks

            Taking weight out is the best mod. And an ND would be an a great car with 50kg or more removed. I loose about 60kg's on my MX5 just from the 2 doors and roof. Actually even more because the boot gets swapped, and I unbolt the complete boot hinge assembly as well. More like 65-70kg's. This car even with aero should weigh under 900kg's, I hope. Not crazy light, but they are a heavy chassis, plus the full cage isn't light.

              This is exactly the skill set lacking in my project

                Youtube is your friend. There are more than enough YouTube videos on making carbon fibre parts. The trickiest part is imagining the resin flow and getting good vacuum. Once you have done a few different things you get pretty good at it.
                You can hand laminate parts, and if using epoxy resin instead of the cheap stuff, you can still get a good product. The trick is to use the least amount of resin possible. I made a carbon fibre hardtop using the hand laminated method to see the difference. It wasn't that much heavier, but didn't sound as tight when you tap on it. So less than half the work as you don't need to build up all the vac layers and seal it, with about 20% weight penalty. Also, with hand laminating, you can't get the cloth into every corner, so won't be a perfect finsh.
                I am actually going to make a carbon fibre fastback for myself soon, but doing it at the shop (couldn't be bothered bringing the pump and gear). I plan on painting it, so will get sandable primer gel coat applied to the mould, then use a bit of filler in the tight corners where air bubbles most likely will form, and hand laminate carbon fibre with a soric core. Will be a good compromise. Probably weigh 3-4 kg's, where a vac infused would weigh 2-3kg's.

                    I'm getting kind of tempted to buy a cheap Nb to throw some shocks and tyres on just so I can get some seat time without wasting cubic $ on race tyres for the sports sedan. What shocks do you tend to use?

                        Just buy a set of MCAs.
                        15x8 wheels with some 225 semis and probably slight guard roll.
                        And at least a off the shelf rollbar

                          yeah mate, 50kg's would make a massive differents, and now with the turbokit even better

                            MCAs are awesome and all, but more thinking BCs for such shenanigans and Nankang AR1s on original wheels, 195-50-15. The main use for the car would be "training" for want of a better word. So cheap and consistent rather than spending 3 times as much for a 10-15% better result. That's what the SS is for.

                              Yeah a set of BC V1's worked fine on my na6, I found the next step up was too stuff for what I wanted. But any if the bc's are good value for what you get.

                              Also throw a set of bushes at the suspension to get everything working again as it should. Most people don't and at 20 or so years old it won't hurt.

                                I'd go to yellowspeeds for about the same $$ as BCs if track is the focus..
