Hi Vincent,
Sorry to hear you didn't like the position of our seat bracket! From your description it sounds like you are referring to the fact that the seat is not centered on the steering wheel. Instead it is shifted toward the door.
This is actually not a design flaw of our seat bracket. The OEM Z3 driver seat is also not centered on the steering wheel. BMW seats are often slightly offset from the steering wheel to optimize space for pedals and drivetrain components within the cabin, a common ergonomic design choice in many performance vehicles. This intentional 'cocked' or angled position maximizes legroom on the right side and ensures space for the transmission tunnel.
Common Reasons for the Offset:
Pedal Clearance: The transmission tunnel frequently crowds the pedal box, pushing the brake and gas pedals slightly to the left.
Drivetrain Constraints: Components behind the dash may dictate a slight angle for the steering column to fit, leaving it not perfectly aligned with the center of the seat.
Ergonomic Design: Many BMW models feature a 'pedal-and-seat' design that is slightly twisted toward the center console to improve driving comfort over long distances.
LHD vs RHD Compromise: Designing one chassis for both Left-Hand Drive (LHD) and Right-Hand Drive (RHD) vehicles can result in compromise, leading to minor misalignment.
While some owners find this design initially uncomfortable, others report that it becomes natural, or note that it's a common 'feature' in other luxury performance cars.
We designed our Z3 seat bracket to sit very close to the transmission tunnel to allow an aftermarket seat to be as centered as possible. However, how centered the seat can be depends on how wide the aftermarket seat is and the posiiton of the wheel compared to the transmission tunnel. If the seat is installed as close to the transmission tunnel as possible, and it still not centered, the only way to center it would be to modify the seat or the transmission tunnel, to allow the seat to be moved toward the center of the car.
We would love to make a seat bracket that allows an aftermarket seat to be centered on the wheel, but unfortunately we are limited by the physical space constraints in the vehicle.
We hope this information is helpful. If you have any additional questions or concerns please let us know.
Thank you!
