I suspect the choice is down to cost and weight (unsprung mass), but I also wonder if size plays a part with the wire wheel option and strange offsets. One thing I found strange when I ordered mine is I was told that Morgan had stopped offering the colour callipers earlier in the year. I was wondering why that was, but thought it may have been due to the MY23 change coming but then the recall happened. One thing I haven’t seen mentioned (apologies if I missed it) is that the ESC stability control will use the brakes in order to work - that may be the most significant factor in any change to specification or supplier, assuming all else was equal (which we now know it isn’t).
If I had these calipers fitted to my car I don't think I would want to advertise the fact with fancy colour options
Looking at historical and current facts. All the trad range until their demise had four piston calipers at the front. The Plus Six still does apparently. The Plus Four has many complaints of brake performance. I don't subscribe to the excuses of cost or unsprung weight which would be minimal. If I'm missing something in the bigger picture I would love to know what it is
