Based on our experience, the link to the steering arm cracks then breaks giving increasing levels of rattle. More seriously, you can also experience progressive fracturing of the welds holding the mudguard together - this also gives rattles. Thus far, we re-weld it but the ultimate solution is something much lighter and more robust - for example the G56 carbon mudguards that we gather are now in use by a few players....
Oh Dear, not more cracks.....
