second part of the September update
As the last update was even quite big, I decided to split the september work report and post a second update today.
Mainly it’s up to the rims today. Maybe you wonder why I started with the rims that early – usually the wheels are the last part of a car for manufacturing. Short explanation, I was displaying a few of my cars (Lotus 79, Porsche 917, Red Bull RB7 and Audi R18 TDI) at the autumn fair of Graz (Grazer Herbstmesse) and did a bit of show building for the spectators. And as the Audi was there displaying, I couldn’t work at the car itself and so I decided to do the rims. The rim dimensions are fixed by the regulations, respectively published by Audi Sport.
The front ones (14.75 x 18 inches) are finished, the rear ones (14.5 x 18 inches) aren’t. What is remarkably, the front rims are wider than the rear ones. But only 0.25 inches, what is 6.35mm (0.6mm at my scale). Compared to F1 rims, an LMP1 rim has a much greater diameter and about the same width. The manufacturing of the Audi rims was more costly than the Red Bull ones. First, because the number of spokes (11 Red Bull vs 15 Audi), and secondly because of the shape of the spokes. The ones of the RB7 were straight, when the R18s have a convex curved shape.
