A90 Supra / BMW ZF 8HP Shifter Square Interface Plate Trim

If you’ve ever used the A90 Supra / BMW ZF 8HP shifter, you already know the problem.

The factory top interface is an awkward, angled shape that isn’t square to the shifter body. That single design choice turns custom console fabrication into a headache and makes clean installs harder than they need to be. 

This replacement interface plate fixes that.

Designed in Fusion 360 and 3D printed in carbon-reinforced nylon, this plate replaces the factory top section and gives you a perfectly square, uniform, straight-to-body mounting surface. The result is a cleaner shifter footprint, easier console design, and a far more professional finished install. 

What this solves

• Eliminates the factory angled and irregular shifter top

• Creates a square, uniform profile for easier fabrication

• Simplifies custom console and trim work

• Improves alignment and visual finish in custom builds

Features 

• Direct replacement for the factory A90 Supra / BMW 8HP shifter interface

• Carbon-reinforced nylon construction for strength and heat resistance

• Square, straight-to-body top surface

• Designed for fabrication-friendly installs

• Ideal for ZF 8HP70, 8HP75, 8HP90 and DCT / auto conversions

Applications

• A90 Supra shifter

• BMW ZF 8HP shifter assemblies

• ZF 8-speed swaps

• Custom consoles and interior conversions

• Motorsport and restomod builds
