The genuine Lag 1 spoilers weigh next to nothing and Polecat confirms that the Lag 2 spoilers aren't heavy either so I suspect that it just a case of the struts getting weak.
I remember when I started out as an apprentice we fitted a genuine rubber spoiler to the back of a Mazda 626 and they included uprated struts as it wheighed a ton!.
As to what speed the Lag spoliers become effective,well I think that you could do 300mph and you still wouldn't gain any meaning full downforce!.
