Well, in every street/track project, comes the time when we have to decide between street usability vs performance.

This is specialy evident when we think in aero mods.

I'm thinking in how to generate more downforce, and for the rear i have a big wing...

Others options to me are: gtr32 oem wing, or something like this...

but i don't think downforce on this last ones be enough... ?

For the front spliter, i'm looking for honeycomb centre aluminium panels, but it seems to be hard to find here...

So i'm thinking to make it from plywood (easy way) or aluminium sheet core (1mm or so) with fibreglass layers, but i can't find anyone did it in this way and i'm a really noob in fiberglass...

I've found other aluminium composites here, like with polyethylene, but density is so high that i think this can be too much weight to get similar properties as plywood or honeycomb panels...

Anyway i'll do some experiments with aluminium and FRP to see how they behave together. And try to figure out how much overhang can go unsupported before it start to flex...

Any input will be very welcome...

That last wing you posted is mainly for high speed stability in drag racing and won't work as well on the track as the 1st wing you posted.

For front end down force, I'd have a go at making a ply wood splitter and see how that turns out.

    • Just checked in first post and you should be able to bring it home November this year, right? I'm amazed you made it through four years of this. As hard as it feels now the rest will go by in a breeze in hindsight, I'm sure.
    • Realized I haven't been back here in a while. Still here, still alive, still waiting for the car.  I went back again the only time last year from Oct-Nov for R's Meeting and drove it around some more, including a few laps on Fuji Speedway(in the wet, sadly). The car still feels good, but have a couple small things to address. I've been getting more parts but have slowed down still, and most of the bigger purchases are now out of the way. I find myself getting impatient more and more when it comes to getting started on this project; it's quite hard for me not being able to really dive in and start making this car my own because it's halfway across the world. At times it doesn't even really feel like I own one of these. Haven't really been motivated or had the desire to document the last trip on here or social media for, well, reasons... but here's some pics...it's also still alive and well as you can see: I've narrowed down to the last large part purchases(anything over $2k) before the engine build to be: 1) Ohlins Road & Tracks 2) ATS Twin Carbon clutch 3) Endless BBK with some custom options and 4) Kansai Service carbon driveshaft I don't think the budget exists for all of these this year, but I'll try for one or two items I think. Though, every time I look at my spreadsheet I sigh, shake my head, and get depressed just that little bit more.  'til later.
    • It's a stunning location!  I've been to NZ twice but haven't made it to the North Island yet.  Definitely on the cards but the South Island is hard to tear yourself away from too... Looking forward to see what you can wring out of it once you can get it to hold together!  Be awesome to get a low 11 or even sneaking into the high 10's pass out of it.  That's a bloody quick car that most people will never experience in their life.  Enjoy!
    • Nominally yes but I’m not really at that stage yet. Outsourcing to Japan is also a relatively good deal at the moment because their currency has devalued much more against the USD.  You would assume this but a lot has changed from the pandemic. Mechanics are in short supply and demand for fixing old cars has gone up from the cost of new cars. 250-300 USD/hr is not an unusual shop labor rate in California and you’re paying that regardless of whether the guy is competent or not. Coworkers have been quoted 3000 USD for a water pump and thermostat at a dealer on an N54. Oil changes went from ~75 USD to 150 on fairly normal cars like Civics. The cost of the oil and filter hasn’t even kept up with inflation.
    • The downside to that is that the cost of everything, particularly labour, is significantly higher here than it is over there in the Disunited States of Slavery. You can hire 3 tradesmen over there for just the Ranger Raptor allowance of a single 3rd year apprentice over here.
