You also have to adjust the settings in the suspension.ini and/or the graphical offset settings in the car.ini, both of which are contained in the data folder for the respective vehicle. In the car.ini you need to look for this:
GRAPHICS_OFFSET=0,-0.050,-0.1750 - these are x,y, and z coordinates. In short - the last number (in this case -0.1750) will move the wheels forwards or backwards in relation to the model.
In the suspension.ini, look for this:
[BASIC]
WHEELBASE=2.286 ; Wheelbase distance in meters
CG_LOCATION=0.50 ; Front Weight distribution in percentage
Those should be self explanatory. You'll also need to play with the following, also included in the suspension.ini
[FRONT]
TYPE=DWB ; Suspension type. DWB Double Wish Bones. STRUT McPherson strut
BASEY=-0.09 ; Distance of CG from the center of the wheel in meters. Front Wheel Radius+BASEY=front CoG. Actual CG height = (FWR+FBasey)+(RWR+Rbasey))/CG_LOCATION%
TRACK=1.286
Changing the BASEY number moves the body of the car up/down in relation the the wheels.
TRACK is of course the wheels distance from the centreline.
There's a BASY/TRACK setting for both the front and rear.
And...
To see all these changes you need to use the "Align using data" setting in the CM showroom.
It's looks/sounds daunting, but actually is quite easy once you've tried doing it once or twice
Cheers!
