No offence here but what have you been sniffing DOlly
The 400 is nothing at all like the ZS mate its like trying to compare water with fire saying theyre the same.
IIRC the zs suspension was designed by some designer from maclaren or some part of mclaren the 400 was designed by a jolly Brummy with a pair of slippers and a tweed hat on
The 400 can not be made to look good IMHO theyre is no kit that makes it look good unless you spend thousands converting it to a ZS
