verdammte Mirek, you type faster than me! :s mash:

Confusing what he's referring to cause I have seen an obsessive attention to weight reduction thru smarter design---and then weight back in to just precisely hubs/upright/BIG bearings/BIG!!! Brakes BIG suspension parts
Unless somebody has a sharp eye they may not mark to the importance of a pivot bolt being 12mm vs a road car 10mm or the wheel studs being 14mm vs 12mm, but those 14mm are multiple times stronger, not just 20-30% but 200%-or more.

But I wonder what he's talking about?

Yes, in those days it wasn't common to use finite element methods to optimize parts while now at least some basic simulations are made even for such stupid things like those tiny flat springs in the rotary knob used to set in-car temperature (maybe stupid example but it's from my job :) ).

As You said many people don't know that the strength of the shape is given by third power of its dimensions... and that there exists steel or steel 5x stronger...

rims and most brakes used at grN are lighter from oem.Competition wheel studs are much stronger than oem too.
Fuchs hit the sidewalk with his rim,at this occasion no 2mm bigger studs wouldn t prevent the wheel to broke.

lucky he didn t destroy completely the ds3

In this particule case 2mm added to 12 studs make quite a difference.
The wheel can still be broken but the possibility to detach and fly away
is much less likely to happen, not to mention the shape of the rim is a key factor.

rim didnt broke at studs surface.So even 20mm studs would have the same result.

agree just bad luck.3 from 4 persons are out of hospital,but one person is inside.

Official information says one injured remains in hospital but without any details about how bad the injury is. The rest was already released.

Now here is a proper rally car with maestro himself:

Karlsson needs to talk to her engineers... who was at shakedown, was it a major fire again?

Fortunately it is not the car this time, only the grass. Car is fine.
