Great thread BTW, helped the most with my Durga.

The alloy mounts are on the whole a good idea. However, it depends on which end you hit at the time, speed angle etc. The front mount is covered by the bumper so it doesn't get scuffed (mine is OK after several smashes) and as the mount is the stronger part any impact gets passed down the line so it shouldn't get "torn" like the plastic kit one.
The rear one on my car has a few grazes from hitting the deck on hard landings as it is not as well protected by the rear bumperette.
As a compromise why not try the carbon reinforced A-parts? That way you get stiffer gearbox tops too. I have some and the suspension mounts seem a lot less flexible than the stock ones. Same for the M-parts but I am undecided on these so far. At present they are fitted to my car but I haven't raced with them yet and if I crash as heavily as last year off the jumps I fear the rear mount may shatter. The good (and bad) point about the kit part is that it flexes a little so it tends to withstand a lot of abuse.
