    Would be interesting to see and to compare with RSRBR.

    Typical M-Sport, they don't care about castor.
    Also rear toe-in is quite big, which is interesting.
    Anybody know what was max wheelbase and track allowed for Focus then?

    BTW. Current cars geo settings I wrote some days ago in other thread - tech stuff

    I also noticed the difference between left and right front castor and found it interesting. If I'm not mistaken the rear toe-in makes the car more understeering, right? That would fit with what Antony wrote about his preferred car behavior. I have seen several asphalt setups and in some there was rear toe-out used. However that was with fully mechanical S2000 cars while Focus WRC 02 was fully active car.

    I think that for 2-litre WRC cars there was same rule for wheelbase as for recent cars which means stock value +/- 1%. That would mean 2615 mm +/- 26,15 mm in case of Focus. I'm not sure though. I have no idea about track limit.

    i would say a little bit different,with toe in at rear, you make the car not to oversteer.

    toe in at rear gives the advantage of having a car that goes on straights in 150 Km/h without crawling. Makes the driver more confident not having to compensate with steering all the time.

    Toe in in rear usually makes car more stable - less overstear, like all above said. Usually in non-active cars most people use some smaller toe-in, but that really depends on driver.
    So if max wheelbase allowed was 2641mm they had still some way to make car "longer" - more stable, etc.
    From what I noticed MSport never really paid attention to castor and all cars from them which I saw had different castor on both sides. Still castor around 8 is nothing special, but don't know the construction of its suspension too good.

    Thanks guys about the toe-in at rear. I actually meant it like You said (less oversteer, more longitudinal stability) just wrote it incorrect.
