I’ve been following this with interest. Replacing the volute springs with rubber blocks is a more sensible way of locating and supporting and engine. But I don’t trust the brackets, at least not those in my car. I have a big-bodied car – the brackets are longer and much more spindly looking than those on a Legere (hence there would be much more room to do the job). One of my brackets looks a bit bent. I’m not brave enough to have the engine just supported by them! I had an engine mount fail in another (different) car a while ago and it caused mayhem. I shall continue to watch.
