Difference between XXX4 and XXX-S chassis

[Toyotachris1982]

I am curious what the main difference between the two chassis's is? I know the wheel base is different but like the XX4 (extra 1/2" that can be noticed when checking between the servo mount and reciever mount or cuts between the cell punchouts ) there is going to be some difference that can be used to I.D a XXX4 chassis. At first I thought the slightly wider cell opening on a couple cells in the chassis was it but noticed some XXX-S models have the same thing. Any help is appreciated.

I have both cars. As far as the Chassis itself goes the only real difference is 13mm in length. All this length is aft of the rear pivot mounts. Pictures for reference, note that they aren't perfect.











Thing of note with old Losi vehicles that I've found while making custom parts, despite the fact that they use imperial hardware, shafts and bearings almost all measurements on the cars are measured in metric, usually within 0.5mm.
