Tried to make a car with functioning suspension and aero, while trying to make it as compact and small as possible.
This is the result, it has functioning wishbone suspension including anti-rollbars (though it doesn't look all that great) and underbody aero. It's still way too portly for my liking, but it's as small as I could manage for now.

Use WASD to control (ctrl works best to slow down), E for push-to-pass/ DRS, and Q for increased downforce.

Power was upped to 2000HP, it couldn't get past 140 otherwise.

UPDATE: Thanks for the upvotes so far. I've since discovered that for some reason, cambering the wheels makes the car quite a bit slower.
To rectify, just remove the wheels and add new ones. Alternatively, I can upload a fixed version if anyone wants.
