Yep number 21 mate, happened to me.
Bought some boge shocks....uncle fitted them (hes a hgv mechanic) he couldn't understand what was going on......then he realised when comparing them to the old shocks.
You have to order them seperatly apparently, i took my car to an ATS kind of place, they put them on for me....and my cars rear sits lower to the ground now....feck knows what they did, i just got really pissed off with it all. You order shocks, i expect all the bleeding parts to be included!!!!!
