Hi
I'm trying to finish up a garage alignment and it would help my "quality system" if i knew the F&R track of a C4S with stock 18" wheels.
My service manual lists C2 as follows
F = 1405 mm
R = 1444 mm
no listing for WB
is it just as simple as adding 44.5 mm to the rear (i think 44.5 is the track increase for WB)?

I'm not sure if Front track is the same between NB and WB.

cheers
