Fantastic car and great thread. I’ve stumbled across it today and really enjoyed reading it.
My big question though, with the house move, have you managed to avoid anyone like “the neighbour from six doors down”?
No one as yet! There’s still time, esp when I have to tune this thing again. My big question though, with the house move, have you managed to avoid anyone like “the neighbour from six doors down”?

Either way just a suggestion it’s your car and video so hopefully no offence taken or intended.

Fabulous car, absolutely beautiful.
Lots going on at the moment!
New oil cooling loop with higher temp thermostat:
Just ordered some custom coilovers for this.
Trying to get the spring rate right for the use it gets.
Aiming for a motion ratio of 1.5/1.6hz, which is about the same as my Alpina.
I'm getting at front spring rate of 180lb/in and a rear of 195lb/in.
This is ignoring any rate within the bushes (as they are probably about 40lb/in) but taking those from my rates would make my rates look very very low!

Throttle linkage all built up now.
Might raise it a little depending on where I can get the injectors to fit.
Also I had a got at mocking the throttle position sensor up. I want it around the back out of the way.
So I removed this bolt from the main shaft and made up a little Ali D piece
Quick test fit of the sensor and it fits quite nicely with room to make a bracket for it.

Since my diff is apart I thought I'd look how my ratios stack up.
This thing is geared long!
I could change my diff ratio while its out.
My options are probably a 3.91 ratio from a 325/328 auto:
Which makes it look a bit maybe too short
Or a 3.46 from a E46:
Probably the best, but quite a rare one to find.

That’s a very useful little spreadsheet - did you build it or find it?This thing is geared long!

I found it years ago, happy to email on if you'd like it. - for those who have only ever known excel it was the dominant spreadsheet application before Microsoft dominated the world of software

E46 m3 come with a 3.62 as standard - they come up all the time on M3cutters. Might be a good inbetween option? assuming you have the big 210 diff?This thing is geared long!
