Samll Euro Designed cars front shocker tower supports

[VX L67 Getrag]

Does anyone know the reasoning behind the design of smaller european designed front shocker towers & why they allow them to float?

It's always a worry to see them drop so much when you lift them on the hoist & how much movement is in them & wonder if there is any benefit of fitting different supports to stop them moving as it's got to throw the alignment out surely?

The 1 in particular today was a 2005 Astra & hadn't noticed on the earlier TS's, but it's like that in all the golf's & similar!
