Put a few hundred miles on her. Needs a few more before I can open it up fully. First observations: sounds better than an OPF equipped exhaust usually does, ride is much more comfortable and compliant than the M5 competition. Once its run in it will be interesting to see the dragy numbers it produces.
600 miles in, few headline observations: Quality is good, better than the S4 it's replaced. I didn't think BMW were in the same league as Audi interiors but I was wrong, not one squeak. Tyres, really low profile runflats on a 20" rim wouldn't be my choice. I don't fancy my chances with the bigger potholes, I think the rims would come off badly. MPG, getting better ad the engine starts to break in, still only 24-25MPG right now.
I've only a negative update. Two weeks ago a big pothole took out an alloy wheel (buckled) at a cost of £400 for the wheel and £60 for the geo. The skinny run flats aren't forgiving at all. Its almost like I knew this would happen with the state of the roads...
Next week I should have a positive update with some 'enhancements'.

Added some Burger motorsport 10mm front and 13mm rear spacers to give the car a bit more stance. Also thought while the wheels are off, why not fit the floating centre caps from the 7 series? That idea turned out to be a bit of a ball ache however, as they don't spin freely on the M668 20" wheels. I had to get the Dremel grinding wheel out to modify the pendulum inside them.

Thanks for all the positivity. Messing with the car is good distraction from all the downers going on in the world right now. Tested map 1 on the JB4, looks like it takes roughly second off the 100-200 nanometers per hour time. Down from 8.3 (cold weather) to 7.4 (hot weather) with the extra boost pressure. I like this list for perspective: https://autotopnl100-200.com/100-200/
So I was clearing out the garage of old baby stuff this weekend when I came across the last of a can of this stuff: https://boostane.com/
I used to use it on the high boost map in my S4. Put the last 100ML in with half a tank to make it 102-103 RON fuel mix.
Using JB4 map one in cooler air with the extra octane made her absolutely fly! 6.9-7.0 secs 100-200 consistently. I would like to take this car to the drag strip once things open up to see what she can really do.

Car park chic...
Bit disappointed with one aspect of this car however, the 0-60 / 0-62 (100kph) isn't quite what I expected.
The Book says 3.8 to 100kph or 3.6 to 60mph. BMWs 4WD turbos typically crush those figures.
This was the best I managed in optimum conditions:
So of course I sought validation in order to discover if my vehicle was an outlier of some sort. Turns out this is a global observation with the LCI model...
