2005 Z4 maintenance/upgrade recommendations? (I'm a complete noob)

Hey there! Just got a 2005 Z4 3.0i in pretty good shape and I'm trying to do ALL required maintenance/upgrades to make it last for another 200k miles. (Not literally, lol) Only mods are coilovers and wheels that I'm aware of.
I've been reading https://z4-forum.com/threads/back-to-my-old-z-time-for-an-overhaul.132861/ and it's been some really good advice. Haven't finished reading through all of it just yet, but I still wanted to ask if the forum had any recommendations on adding/subtracting things from my to do list?

This is what I have right now:
List of things to fix/replace/maintenance to do on the Bimmer:
HEAD UNIT (getting today)
Adjustable rear camber arm
Belts replaced
Fix top
Oil change+filter
Transmission fluid change
Diff fluid change
Replace Brake Rotors. (from another BMW?)
Replace upper radiator hose
Replace O ring on radiator temp sensor

Xenon headlight
Wrap
Clutch changed
Possibly forks if shifting doesn't crisp up with the clutch
Short throw?
Fix the center caps on the wheels
Exhaust upgrade (Valvetronic with x pipe and some resonator, not sure which yet)
Bushings replaced
Motor Mounts replaced
Speaker Upgrades, ofc
OEM wheels (getting today, probably)

Any brand's y'all would recommend? (especially for the camber arm and bushings/motor mounts) The top 10 things to do are items I'm getting fixed/replaced ASAP, and the bottom 11 are things I'm slowly getting to. They're in a rough order on the maintenance side, anything I should do earlier/later?
This is just for the street (I'm way too broke for a track, lol) and my goal is OEM+. I'm also on a tightish budget, as this is a 200k mile car I got for 3,500 USD, so not looking to spend a ton except on the sound system, which I will be taking with me when I do a supercharged Z4 M build this car is leading up to.
Thanks for the advice!
 
Welcome to the forum. :thumbsup:

That's a pretty comprehensive list already!

I think your car will have 300mm front rotors, but facelift 3 litre models had 325mm as did E46 330 models. I'm guessing you'd also need different caliper brackets, and possibly calipers.

Removing the Clutch Delay Valve can help with the shift quality, as does a shorter, heavier ZHP shift knob. If you buy one of those make sure it comes from BMW as there are plenty on Ebay, etc. that look right but aren't weighted which kind of misses the point!
