  1. small update. cutting down the wing mounting to a minimal form. I need to choose whether to leave it bare aluminum or paint it black. Any opinions?
  2. this forum has really slowed down but I thought I'd make a brief update since it's been a while. I've been driving the car, slowly tuning the setup. You can imagine that a completely custom chassis is going to have it's own pros and cons to discover and tune. Right now just finishing up installing a new set of springs and 2-way adjustable shocks. We are adding some rock shielding to the engine back- the open wheel wells are cool looking but invite all kinds of rocks into the engine bay. Also working on adding a wing to the rear for better aero.
  3. I'm still working on that question. I spent the last few weeks tamping down a long list of NHV issues- so many panels that were rattling. It meant I haven't driven it enough. But what driving I've done is encouraging. It's frighteningly fast, so much so that I need to put in traction control asap or all that power will be a waste. There's a funny oscillation effect that happens with this P/W ratio- if the car hits a bump, your foot can tip into the throttle a bit, given the throttle responsiveness, the car takes off, so you back off the throttle, and the car slows, causing your foot to tip into the throttle again. back and forth. crazy. I need to create more of a ramping to the throttle input since it's an electronic map. That will dampen the sensitivity at mid-throttle. I've experienced the same with a FF Cobra with a Coyote in it. Afa handling, the springs are too soft so those need to be replaced. Otherwise it feels balanced and controllable. I've yet to see how it handles a hard day at the track.
  4. yes. you got it right. adjustability. and behavior under compression.
  5. Art Morrisson CNC bent. Wouldn't do it again. They did a great job but we ended up cutting them anyway to improve footwell space. Would have been easier just to start with raw steel. But they did fit the Z06 front end for me according to specs- so some convenience. Ha! rear suspension. yes. crazy. I did it for fun. Totally not necessary. But cool.
  6. Thanks. Only after making the dash and center console I found a vendor that is making them. It would be far cheaper to go with them ( https://retro-spec.myshopify.com/collections/datsun-240z-260z-280z-s30) The wheels are 18x11. The design is custom one-off. Boze wheels fabricated them. I've done a preliminary shakedown. It is wicked fast. Scary. at ~2200lbs it's easy to get moving. Handling is good but springs will need replacing as it's too soft.
  7. slow to post but a few weeks ago I took the car to Nismo Fiesta and the car won Best of Show. Pics from the show below. Warning- they are fuzzy. The camera lens was messed up. It also turns out red is hard to photograph. hmmm. I had only just picked the car up from the paint show the day before so it was a rush to get it there. For the last few weeks I've been working on finishing up the interior and lots of small bits of refinement. A final set of pics will be coming soon. Then I hope to call the project finished and just enjoy the thing. It's been a ten year project. https://farm1.staticflickr.com/943/40239399110_240591301f_h.jpg
  8. The paint has been sanded, cleared, sanded and polished. It looks beautiful. Next week we will clear the carbon parts and put the car back together.
  9. It's Audi's Masano Red- the color they use on the 2008/9 RS4, among others. It's a brilliant 5-layer red that has white underneath it.
  10. The car is very nearly finished. After nearly 10 years of work it's finally painted. The red is beautiful and is striking when you see the contrast between the painted parts and the naked carbon underneath. I plan to show the car for the first time at Nismo Fiesta in San Antonio in Mid April.
  11. The car is still at the paint shop. The body is almost prepped for paint. They did a fantastic job making everything fit nicely and straightening out all of the surfaces.
  12. The body prep for paint is coming along. It's taken a lot of work to take the subtle waves and kinks out of the CF body. But it's close and looking perfect. It will hopefully get painted next week.
  13. You're not the first to react that way. There's always the "you're painting over the carbon fiber??" reaction. So here's the logic: First, the CF work is ok, but we made no effort to ensure the weave ran consistently across the body. it's all over the place. And the molds have all kinds of small errors that reflect my original Z's body errors. It doesn't survive close inspection. It also seams against the few remaining steel elements like the doors and roof (safety!) And I wasn't into the idea of building some kind of raw naked-tech racer. The vision for the car is as a refined material and mechanical platform that reveals itself only upon close inspection. At first read it's just an old 1970s Z car, albeit shiny paint with flares. The magic will be in how all the materials and technology reveal themselves as you open the doors, lift the hood, etc. For example the hood is painted on the outside...relatively normal looking right?... but lift the hood and ...omfg... underneath is a custom chassis, motor, and naked carbon inner hood surface. I think it'll work.
  14. small update. big news. Car went to paint a few weeks ago. Starting the process of getting painted.
  15. FYI. I'm bringing the car, along with my RBZ, to the San Antonio Nismo Fiesta this coming Sunday, April 30th.
