Of course it could also be done by making the hubs in alloy with lower mounting points for the tca and track rod end. But I think that combining it in an adjustable tca would be cheaper and easier to sell. That way it would also be nice if there are adjustable TCAs where the ball joint doesn't wear out quickly like on the compbrake items.

I don't know what Zoo made in the past, but there are several existing kits for different cars so it can be done in a safe and reliable way.
