Z4 aftermarket performance options?

[TacticalSpeed]

I know the G29 Z4 has the same drivetrain as the Supra. I am not considering the Supra b/c I want a convertible.

Clearly, the Supra aftermarket is great. What about the performance, and even appearance, aftermarket for the Z4?

Also, while I am here, did the 2019-20 Z4 have all the same factory options that the 2022-23 has? If not, what are the differences?

I’ve seen a few remaps available and there is always the schnitzer upgrades.

Racechip do an add-on harness and control chip which gives the car up to 400ish HP and is easily removable and tunable within it's software.

That's only 18 more HP over stock...
