In a moment of itchy finger, I somehow ended up with this. I had a 2004 Z4 3.0i about 20 years ago as a 20 year old and I absolutely loved it. Was sorry to see it go then when I needed more space.
Bought unseen without even speaking to the seller so today's the first time I've clapped eyes on it.


It's now insured and taxed and I've transferred one of my registrations over to it which I'll put on once it's home. I've 'owned it' for a week but haven't had a chance until now to collect.
I plan to bring it back to as new condition and I'm 99.9% set on supercharging it.
Already has -10mm springs on it, genuine CSL wheels and an Eventuri carbon intake. So I'm not totally sure where to start. But will document it here.

Wish I never sold mine, but the first car I ever sold and got more than I paid for it 3 years later.
You can drive over 120 and not get too much wind in the cabin and that engine loves to be reved to the red line. Our MK3 TT is rubbish in comparison for wind, anything over 60 and you feel like you're getting a blow dry 😉.

Having the underside powder coated, needed a new battery and wipers, new engine mounts, ZHP gear knob ordered, new rear 3rd brake light as it was a bit untidy, service and MOT, new headlight washer jet bracket and cover to be painted and fitted. Will probably respray the front bumper at the same time. Put a reg plate I had on retention on it. It also needs a new window switch.
Headlight washers on these are a PITA!
The covers are prone to flying off, jets often leak or escape completely, and even when they work properly you get streaks on the paint that really stand out on dark colours.
Once I got my leaky one fixed I pulled Fuse 40 to stop them working (or more likely breaking). Even with Xenons they don't need to work on cars registered before 2009 for the MOT. Mine has passed 3 times without them.

Eisenmann Race, ESS supercharger and engine/gearbox mounts ordered today.
Giving some thoughts to brakes and other bits.
Great news - I'm looking forward to reading about the supercharger! Giving some thoughts to brakes and other bits.
Engine and gearbox mounts are a good idea. I had my bearing shells replaced at 78K miles and the original engine mounts were in a terrible state.

Jeeesus, that's impressively quick work buying the supercharger.. look forward to seeing how you get on with it.
There was a guy who frequented the forum, I think his username was something along the lines of 'BeeDub', who had a silver Z4M Roadster which was supercharged and I'm sure he kept a fairly detailed journal on his ownership.. which could be helpful for you going forward.
It was either here or M3Cutters, my memory isn't quite what it was.
