Thank you for taking the trouble to post, I really enjoyed that. My word it looks complicated and though its obvious really it is nevertheless fascinating to see the exhausts coming out of the top of the engine.
A couple of questions.
Are the centre locks handed?
I see you can get 0.5g braking from the e motors. As an electric motor has max torque at zero rpm I wonder how they modulate the braking effect to give more gentle retardation?
Yes, the centre locks are handed. On the Weissach cars, they have red and blue wheel nuts similar to those on the CGT. A couple of questions.

Good question on the e-braking. As you slow to a rest, the e-braking force is reduced and the hydraulic brakes come in. It does make braking to a rest challenging, as you can feel the change through the brake pedal and it makes the pedal hard to modulate for a smooth stop. You can also hear the pads on the rotors (a “shhhhshh” sound). Many people commented on the brake pedal feel when the car came out - when really pressing on (e.g. on track) it feels great, but it isn’t perfect when braking gently for this reason.

Brilliant pics and car, and in the other thread too.
Curious about the purpose of the light grey hoses in this picture? They seem quite flattened where they bend and twist, but obviously not an issue, or I am sure it would be getting dealt with!
Those look like lambda sensors so my guess is that the grey ‘tubing’ is actually thermal insulation protecting much thinner electrical cables routed inside.Curious about the purpose of the light grey hoses in this picture?
