Technical Analysis: WRC Cars 2017

[Mirek]

IMO the advantage of keeping the camber is more of an advantage in off road races where there is a need of good traction even with rather extreme positions of wheels. On the other hand these cars have usually huge wheels so they don't need to care about small bumps/holes unlike WRC cars with rather small diameter of wheels. Those huge wheels are also heavy so the weight of suspension alone doesn't play that big role.

Double wishbone shall be better for heavy braking as well and as it was already said it's more robust and can take more beating.

IMO there is another advantage of double wishbone and that's freedom of setting the castor. With usual McPherson setup there are massive forces in the steering coming from huge castor (angled strut) and with that more reliability problems appear.

Take is as an amateur talk anyway
