Hello folks, I recently removed the DRC set-up on my 2006 RS4 and fitted a new Bilstein coil-over kit. I now have the old metal lines still attached to the car but would like to fit blanking caps just to tidy the whole thing up. Does anyone know the thread sizes/type for me to try and purchase some blanking caps? Long shot, does anyone know where I can buy them? Thanks in advance Gents, Graham.
