Oh sorry for getting back veeery late, but I don`t sign in here so often, and I just saw Your post right now, a couple of weeks after You wrote it..
Anyway; i don`t know a lot about cars, but I think I know a llittle more than You expect me to...
About camber: I said "I don`t think...." - I dodn`t say "There aren`t...." But it will be rare with zero camber. You found that Ferrari - OK I believe You.
I didn`t say anything about positive camber, I only talked about zero camber. I do know that positive camber is/was used. I remember (loud and clear) the Fiat 127, which had an enoumous positive camber, so much one could see it. It`s front wheels was literally "hanging out" on upper part. There are more cars with positive camber, but negative is more common...But zero camber...When You say it, I believe You.
Reason why I doubted zero camber: Well a teacher from a technical college told us long time ago that camber was "invented" as wheels simply would fall off without it. Work their way outwards on the axle - and fall off. Lock nut and cotter pins etc would just make the wheel ruin the bearing instead (Burning hot and block) - so fundamental physical laws demand camber... However I cannot find that statement anywhere, so It`s hard to get it confirmed...
Off course there`s a lot of litterature on camber-caster-toe etc etc on the net, just not what I`m looking for, namely "will zero camber make wheel fall off?" (lols)
Toe...Well zero toe on front wheels is dangerous. Wouls cause tonnes of accidents, so always toe-in on road cars. They might use toe-out on race cars though, but in daily traffic it would prove disasterous...
Rear axle....I guess most FR cars have a tiny toe-in rear, whereas FF cars can have a litle toe-out...Eventualy zero toe rear, why not...
But if You look at GT6 "default setting" You will find (on road cars) an extreme toe-in rear (0.60) and zero front... Extremely unrealistic...
Replicas...I didn`t "judge" on replicas, I questioned them... Thats all...Because it appeared to me that people here building replicas might have a strong belief that they were exactly like the car IRL... But...people are smart enough though, so my post was really not nescessary...Not more to say. Sorry for getting back 2-3 weeks too late
