Cables
Why Bullet has flat bar stock for splitter supports instead of cables and also why none of our cars have cables anywhere.

I need to ditch my cables ASAP

Nothing 15 seconds with some side cuts won't fix.

I'm working on a full Under Aero for my daily, so here is some work on the front diffuser and the rear diffuser is right behind it.

Theres a reason I added side support to my wing the way I did and refused to use cable.

Here is one we are preparing for the ClubSprint (street) class at the World time Attack Challenge. Dann |
Looks good. Are the indicator intakes necessary?
FYI - I had to go bigger on the splitter for balance and the bigger we went the faster we went.https://cimg7.ibsrv.net/gimg/www.mia...9775dd95c6.jpg |
Actually I ran the same size splitter as you have made and ran it at Pukekohe with the usual wing for a lower downforce setup and had a scary lose of the front at turn 1 which is near flat in 6th! (Hankook Z214's notorious for no feedback letting go)
I honestly thought the suspension had broken it was so sudden. So I vowed to never run that small again! :) |
The rules force this size. I think i will add some canards.
Lights just happen to be uninstalled. Dann |

Any of you guys who have built your own floor, I'm currently making some test composite sandwich panels and wondering what you see in terms of load deflection? With my first off sample, an 11mm (7/16”) thick 300mm (12") wide strip, I clamped it to the bench hanging off 500mm (20") and put 2.3kg (5lb ish) on the end and saw 17mm (11/16") of deflection. This was very lightweight as I will continue to build the skin thickness, but just wondering if anyone else had made similar measurements?In case anyone's interested this was 600g/m² (18oz) fiberglass skins either side of 10mm blue modeling foam (polystyrene), weight is about 2.7kg/m² (5lb/yrd²). Comparisons are being made with carbon skins and different core materials, will see how I get on. |

Just curious if anything ever came of this. Didn't see anything in the other old composites thread. Am contemplating attempting a fiberglass/foam core sandwich for flat floor/diffuser. I do not have the time/money/patience for vacuum bagged CF, and am looking for cheap experimental alternatives to the dibond I have now, which is heavy and requires a lot of additional bracing for rigidity (I have to mount below the "frame rails" in my RX7 due to exhaust, trans, diff, and bellhousing clearance issues.) There are some shapes in the back I'd like to play with that rule out other flat/plate materials like alumalite.
Remember that with a core, what ever side the load is on is the side you make sure its stronger. If you put weight on your laminate from the top, the top will most likely fail withe carbon skin buckling and over lapping itself and not the other side ripping the CF. https://compositeenvisions.com/carbo...z-50-1115.html What I've figured after years of working with composites is that what ever the thickness of your composite CF/Core/CF is going to be as stiff (not as strong) at the same thickness of T6 Aluminum. |

I build CF panels for Military OEM C-17 Air Craft. I would go CF because the cost is lower than ever.

I just question whether its worth the price difference since I won't be vacuum bagging. Seems impossible to tell if you've got voids/unsaturated areas like you can with glass, which negates the whole purpose.

Epoxy resin is a definite since I'd be using a foam core. Made that mistake before!

Rear Wing on my '91 car for the German Solo Championship
https://cimg5.ibsrv.net/gimg/www.mia...c07c1fc30e.jpgView from behind, You can see the two wing-profiles, mounted on aluminium recks.
https://cimg9.ibsrv.net/gimg/www.mia...4202409fce.jpgWith aluminium endplates, the upper wing is adjustable. https://cimg1.ibsrv.net/gimg/www.mia...8663706c95.jpg Price approx 600Euro, made from Aluminium and Carbonfibre. The size is in compliance to the rules in the German Championship, that means that all aeroparts should not to be seem in the front projection plane. After one year of driving with this wing I'll found that I will need (only a little bit!) more downforce on the front axle. I started the work on a splitter splitter these days and give fotos to this platform. Jan |
^Nice work

Indeed. What are your mirrors? I like the shape.

I found these: https://global.rakuten.com/en/store/...item/10000025/ Need to do some more digging but probably something difficult to source in the US. |
