they are for the fronts you know that right? i have a mate thats using them on his bora, good for what they do but they replace the rubber top mounts so its a pretty hard ride and you can get knocking where its metal on metal
 
Hi, yeah I realise there fronts. I'm glad I asked then I don't really want any knocking chances.
Thanks. Do you know of any other solutions?
 
no i dont think so, there is a little bit of adjustment on the lower arms i think, if you take it to a wheel alignment shop they should be able to set it all up for you
 
I have the silver project top mounts. No knocking or metal on metal noises with mine.
They're obviously not going to be as compliable as a rubber bush but fitted correctly, you shouldnt have any untoward noises
