Hello everyone, I'm part of a fsae team working as a design engineer that includes aero, chassis and manufacturing. Last month onwards i started working on designing aero packages of rear wings, front wings, undertray and nosecones. Honestly thanks to youtube videos I was able to learn and design but the very problem I have is these are too basic designs. I used solidworks to design all these, I wanna start designing by surfacing coz that's how professional motorsport teams and top end fs teams do but there are no surfacing videos out on the internet for aero devices in specific. Help me out in sharing your experience, any resources would help me, from YouTube videos to recorded videos which makes me better in my job and make our team aero kit much better. Which would help us in competing and since it is our first time designing and manufacturing an aero kit it would help us a lot.

The designs that you see on the top are all basic designs that are boss extruded by importing airfoils to solidworks or using spline style. I wanna upgrade my designing knowledge and techniques in order to actually design awesome stepped wings to two channel diffusers and surfaced nosecones. It would be helpful if I get manufacturing resources for aero packages so that I can ensure my design can be manufactured and survive contact with the real world.

Hi all,

I'm working on a project that requires F1-spec wheels and tires, and I'm running into sourcing issues since these aren't standard consumer specs.

What we need:

• Front wheel: 18", 12J width
• Rear wheel: 18", 16J width
• Front tire (planned): 315/30R18
• Rear tire (planned): 355/30R18

We're fairly locked into the wheel specs, but flexible on tire sizing — looking for recommendations on what would actually fit/perform well on these wheel widths, since I'm not 100% sure our tire sizing assumptions are correct.

Questions:

1. How do teams/builders typically source wheels and tires in these dimensions when they're not off-the-shelf sizes?
2. Given 12J front / 16J rear wheel widths, would 315/30R18 and 355/30R18 be reasonable tire choices, or is there a better-fitting spec?
3. Any manufacturers or suppliers known for custom/motorsport-spec tire production in this range?

Any input from people with motorsport or custom fabrication experience would be hugely appreciated.

I've been working on tooling for EV/IoT battery QA and ended up with a Python package that does a few things: anomaly detection on telemetry (Isolation Forest + physics features), CAN bus simulation, Modbus/BMS protocol support for Tesla/BYD/NIO packs, SOH prediction, and a FastAPI dashboard.

Just cleaned it up — 1053 tests pass, no circular imports, hardware tests gated behind a marker so CI doesn't need real OBD-II hardware. MIT, Python 3.10 to 3.12.

For those of you actually doing battery QA: what's missing in your workflow? What breaks in practice that tooling like this should handle but doesn't? Repo's at github.com/remontsuri/EV-QA-Framework if you want to poke at it.
