Not sure what that means, but thanks?

That's an amazing mileage. About 4x more then any of my exhaust sets lasted so far.

You could start here;
chassis cracks

Thanks, I'll do so and scrub around some other posts as well. Hopefully you run into more of a Wedge situation with yours and not a Biggs.

Calum my crack is very similar to your 2013 crack on L/H side. Maybe the welded in fillet is doing more harm than good. Did MMC cover full repair cost with both incidences?

Matty, you raise a very significant point on the issue of “fit for purpose”

I have followed what seems to have been a rather sorry tail of the early versions of the M3W for some time and am surprised this as not been considered more seriously although I recall it has been raised on this forum previously.

Given the litany of problems with bevel boxes, broken exhausts, bump steer and chassis cracking etc; it would seem the vehicle may not fit for purpose and could be dangerous.

Sure, work with Morgan on a fix for these early vehicles if there is one but it could be worthwhile making a clear, factual, structured submission to the relevant motoring authorities in the UK, Europe or the US as well as the appropriate consumer authorities. It’s not a difficult exercise and at least they are on notice.

The consumer authorities course of action (called Fair Trading “downunder”) was considered in Australia when suspension and compliance issues first appeared and we got stone walled however the Federal Department of Infrastructure and Transport (our motoring mandarins) stepped up to the plate very sharply to sort the issue and as we now know have been keeping a eye on things.

i have the chance to drive 2 times M3W, but i never consider to buy one for all of this problem the car/bike is fun but come with a price and have several issue not yet solve, i feel when one is solve come out an other one.

I hope the E3W will not take face at such trouble

Tim, talk directly with the factory - MMC covered the cost for my cracked chassis, chassis replacement under extended warranty following the mandated chassis inspection. For me both sides had cracked and Matty found them to my utter horror at Brooklands, I was glad he did though.

I had some additional mods done at my expense at the same time.

Took another look at Calum's crack photos - the worst part of that location is there is no accessibility for a welder torch. That would require major strip down of the body and components.

Hi Tim
Yes, MMC did both change outs F.o.C. Both times the car went back to Perth as the logistics of getting it to me in Aberdeen when I was actually here to receive it were just going to be much more of a pain than me jumping on the train to Perth.
That kind of bracket is very inclined to move the stress raiser and the failure point rather than preventing it. I've been involved with ship repairs and modifications where a similar arrangement was used but the end of the bracket was very carefully shaped to maintain flexibility and the weld was built up then ground back smooth to avoid the stress raiser of the sharp turn in the weld so that the fatigue life would be greatly extended.
I had my doubts about the bolt in triangulation brace being effective enough to restrict the movement sufficiently to prevent the cracks initiating and if they were already there, possibly subsurface, then stopping their propagation would be unlikely. New chassis has to be the best option.
