steering wheel and braking issue

[dodospor]

hey guys , i have bmw m4 2016 , stock suspension and not lowered or anything , the issue i have is the car pulling to right on high way checked two diff shops and they said its because the crowns , i have tune on the car , i heard software will fix the issue . can i just update the steering wheel without whole software update so it wont affect my tune

second issue is the car shaking under-braking when my speed is around 75 mph , checked if the rotors are wraped and check all the suspension competent and everything is good , also my steering wheel vibrate little bit around 45 mph that happen when i left my hand of the steering for few seconds.

if someone help me and give me advice , i been trying to solve these problems for the past month and cant figure out whats wrong with the car
went to different shops and they find my car drive normal but to me is not.

Note: changed wheels and tires and did alignment couple of times and road force balance also tried cs and gts steering wheel and still no luck , also no spacers

thanks

Check if vibration is related to specific speed. Very often is an unbalanced wheel.

Related to brake sometimes is just uneven pad material deposit on the rotors. I would try to bed in the pads again. Just search online for the procedure
