MG ZR: Cams & Maps

[lolsteve]

So ive had a bit of a knocking noise from the front drivers side suspension ever since getting back from FCS. it would come about after pulling away when applying the brakes for the first time 
So i checked the pads, seemed fine.
Then it started making knocking noses over bumps and when pulling away.
So I jacked car up and shook the wheel, no unusual play. Put a bar under the wheel and lifted it, no click or knocking noise.
Then i noticed a knock when turning the steering wheel, so put it down to top mount bearing.
Got old bearing out and it was very stiff and took alot of work to rotate so replaced and greased all the top mount/top of the coilover. Also checked drop links and apart from looking a bit old they didn't seem particularly perished and didnt make any noise when rotating them. 
Back on the road and the knock is still there although not as aggressive and seems to be coming and going. 

Got a bit of a shaky wheel at high speed too but think that might just be wheel weights 


Any thoughts? Should I have coated the top mount and the bearing in lithium grease?

Also sorted out the cold air intake, decided just to use the oem intake. After refreshing myself on about static pressure, dynamic pressure vs velocity i thought perhaps rover knows best
