After some test drives I realize i deeply hate cars with big oversteering issues. Added two shark fins to the back of the car (on the rear wing) for vertical stabilization to fix the said oversteering issue, removed and shortened some unnecessary connectors for looks and maybe like 5 kilos of weight reduction, added back one carbon wing piece back to the front to tighten the turning circle but not on the same place as initial release because there it almost always smashed into the ground. The car now is still oversteering and sliding but doesn't spin out of control. Doesn't even spin out of control with handbrake turns. For me that's a big win.

reduced size of the front wing to reduce oversteer and the front wing smashing into the ground on more uneven ground

initial release
