Engineers design racings cars with low centre of mass and widely spaced wheels to improve their high speed cornering ability. Explain using moments, how this helps.

The weight times the distance is the moment. The moment increases with distance from ground on turning through a bend the possibility of toppling is then greater if the perpendicular line from the CG gets outside the area of the base of the vehicle. The same reason the wheels are spaced as far as possible and made as wide as possible so the projected vertical line is almost always inside the base projection on the ground!

cars that travel fast, over 180 mph, must have a low profile to reduce air drag. air resistance increases as a cubic function of speed. that is why cars that travel on oval circuits use low squat vehicles even though they don't have the tight turns of formula tracks. the relative wide spacing of the wheels actually reduces the tracking stability making going straight a problem let alone cornering. much like driving a military jeep.
