As standard the mod has the cockpit set too far to the left of the screen , im not sure if this will cause mismatch but if you go into the three cockpitinfo.ini files in gamedata/vehicles/caterham and change this line (its the very top one so easy to find)
"Eyepoint=(-0.282, 0.695, 0.738) // cockpit eyepoint (left/right, up/down, front/back)"
to
"Eyepoint=(-0.255, 0.695, 0.738) // cockpit eyepoint (left/right, up/down, front/back)"
Now the wheel should be in the middle in cockpit view
The exact file names this line needs to be changed in are "cat_cockpitinfo.ini", "KL_cockpitinfo.ini" and "R500_cockpitinfo.ini"
