Now, you can't compare a CX with a 4/4; everything is much more modern and innovative on the CX. I got three new brake discs for my 4/4 during the warranty period. Each time, it lasted 7000 km and the ugly wobbling of the brake discs came back... with an exponential increase to an absolutely poor and undriveable state. Then I changed the garage. The new workshop has mounted new brake discs. Then these new brake discs were tested on the car, they still had a very fine wobble. They were just ground, brand new, with a kind of diamond knife or something similar, when they were mounted on the car. I think it's called skimming. I have had absolutely wonderful smooth brake discs since 80,000 km. (On the 4/4, they literally last an eternity). I think that if I got it right, you have to skim the brake discs when they are brand new, because the slightest lateral runout quickly increases to the point where they are no longer usable. In my case, it worked.

Seems odd as you should have I think Brembo brakes. Do you have wires? Unlike trads the wires have an adaptor plate and I know on the launch cars this caused vibration issues as the holes for the bolts were too large.

Credit when its due, give Morgan chance and they do try and resolve issue's. That's a lot of parts changed for a wobbly disc.

Very true. They seem very hot on warranty issues.

The wheels are alloys not wires.

Not sure of brake make as they are branded "Morgan". Thought I had read somewhere recently that P4 and P6 brakes they were from AP Racing . Certainly AP Racing web page mentions Morgan where Brembo does not. I should maybe ask the question sometime.

I might be confused. I know my MY22 ones are Turkish tractor brakes

There is a Lambo tractor near a road to the Stelvio Pass in Switzerland
