Hi,
Was just wondering what crown and pinion ratio (and type of diff) is being run in a 2023 Z4
Can this be altered by changing crown and pinion, and is this possible for the axle setup ?
thank you
 
Don't know about the technical question, but the diff ratio will depend on which engine you have and what transmission.
So, what do you have?
 
Probably best if you tell us why you want to change the axle ratio, the HP8 automatic has direct drive in 6th gear 7th and 8th are both overdrive, so there is a wide range of driving styles covered already. It also depends which version of the B58 you have and the electronic control choices for the gearbox on your car.

Hi, it is a B58 (I think) 6 cylinder with an 8 speed auto.
Thanks
