the-wirewalker....there have been previous/older posts in respect of the ride and dare
I say the height/ground clearance of the 454.
For many; escpecially Brabus owners; who would like a smoother more compliant ride the
solution appears in their case to be to change to a smaller wheel diameter (16" v 17") and
go up a level in the profile to resolve the problem....as in to go from 205/40R17 to 195/45R16
which is the same ride height but taller tyre sidewalls for 'comfort'.
For increased ground clearance on a non-Brabus,
Alex went from 195/50R15 to 175/65R15
and fitted CDI front springs....and at the rear fitted 4cm tall spring spacers and even bigger tyres
of 185/65R15) for no good reason other than looks !
(according to this post :-

One always has to bear in mind that if one changes tyre sizes from original that it will affect the accurancy
of the car speedometer...even allowing for the actual misreading of almost all old car speedometers.
Thankfully, most if not all SatNav's show a more accurate speed reading....so one can use that if one
is worried about getting caught by speed camera.
