Given the cars don't come with them in the first place clearly the forces they'd have to cope with would be manageable by some moderately designed replacement, it's hardly like it'd need to be the size of a scaffold pole
Very true. I get round the rubbing issue by having a pair of Melvyn Rutter's roller stops rather than the rub plates, they can be set a bit further out so the tyre shoulder contacts the roller before the sidewall touches the reaction bar. You lose a bit of lock that way but as it's only a 4/4 the steering is hardly what you'd call heavy.
