Gewinde in standard beetle - ???

[Bogara_ZO]

hi guys! I'm planning to upgrade my front suspension..I have found a solution on Remmele's website which seems very impressive to me. But I have doubts about this set up, I don't think that a stock front beam is strong enough for it, I mean usually it is the top of the beam that starts to rust first during the years... But on the website it is written that can be used with normal axle so they don't offer a stronger one, and most of their cars are with this suspension.
Does anybody have some further informations about it?

here is the link, I'm speaking about if it's not clear

http://www.remmele-motorsport.com/en...cooled_en.html -> suspension -> the last one

By the way, what about using this idea on the rear too?
thanks
