OK right, got it out the shed, now i have an urge to get this right, and i've had an epiphany!
Had a closer look at my picture of when it was fitted to my gti, and the photo on APR's website.
Where the red arrow is pointing on my picture, the subframe looks slightly different.
Then i thought, there's 2 types of dogbone inserts for different aged gti's, so what about the subframe itself??
So now i need to find out, is the subframe different between these models? could THIS be the reason that i get a knocking sound?
And what can i do to rectify it? shave off a bit off the mount? Getting ahead of myself here though
