I recently got z4 m40i as loaner when my 3 series is in shop, but I feel z4 is not that stable on city roads when taking quick turns with b58 engine. Could you please explain why I feel 330i drive is more stable than z4? Is it because of rear wheel drive and b58 engine?
If the rear wheels are slipping going around the corner that’s called oversteer. That’s actually want you want to be fast on a racetrack. It helps the rear of the car rotate around so you can get it pointed in the straight direction and under full throttle sooner. Unfortunately, it can get away from you and you can wind up in the weeds.
