sway bars

Howdy, you might want to talk to Firm Feel. Dick is a nice fellow. I have purchased several sway bars from him including custom 1 - offs. He carries what you are looking for and can explain how it mounts up etc. Nice thing is they manufacture their torsion bars and sway bars them selves in the USA. :)

They have a lot of well thought out, heavy duty and performance handling parts.

Oh, I just realized you are in the Netherlands. Maybe this does not help you then..
