If MMC denied it was an issue why did they panic and offer to fit triangulated bolt-in chassis braces free of charge to all of the early cars.

MMC originally said that this problem only occurred on cars that had been driven very hard in competitive conditions for long periods of time but then many people who had only used their cars on the road and never even done a track day had cracks appear in their top tubes.

I agree that this should never have been a problem if correct CAD and FEA software was used at the design stage and a more suitable material such as Reynolds 531 tubing used for the chassis..

What worries me is that when a crack first starts to form it would probably be invisible to the naked eye, particularly under the paint, and do we know how quickly a crack can go from the initial invisible stage to the life-threatening stage.

If both the top tubes crack and this goes un-noticed, how long before the bottom tubes crack and the entire front end falls off?

If I was a member of the executive team at MMC, I think I would be having a few sleepless nights.
