Update...
I've been back twice, first time took the rear apart to replace the top and bottom rubber pads, old parts were no worse than new so decided to wait and get the TT pads.
Back today to install the TT top pads, height is up on both sides but now the drivers side rear is lower by almost 10mm.
I probably wouldn't have noticed but since this was really evident from the beginning my eye is now drawn to it!!!!
Any suggestions guys? Will adjusting the camber again on the rear make any difference?
At a loss now short of sending the springs back to Eibach to test (at my cost)!
