Hello,



I’m starting to restore my Z3. However, I’ve noticed some rust in the battery tray, which I plan to treat. Do you have the part number for the primer used to match the original color?



Does anyone know what this unused connector is for?



Also, to make things easier, I’d like to remove the plastic tray: how do I take it off?



The lower Harman Kardon speaker is broken. While I’m at it, do you have a recommendation for one with better sound quality? Note that I believe the impedance is 2 ohms.



The rear stabilizer bar mounts are bent: is it worth installing reinforced ones?



Thanks for your help 🙂

The unused connector in your first photo is for the handbrake cable, there are additional holders for it on the bottom of the fuel tank
