Hello, I installed on my 99th TDI 2 years ago the full impact limiters, which are in the part program for my SMI steering gear. I think the plastic discs were black. Somewhere between the lines here in the forum I read something about (meaning) “…the thinner blue (?) steering stop limiters are sufficient for maturation. I drive 205/50 R16 or in winter 205/55 R16 and have mounted 5 mm track width at the front of each side. The big turning circle is annoying. Are there thinner discs than the black ones with the above mentioned part number? -Did the track width have a positive influence? -Couldn’t it be, though? Grinding should not be. When buying the car, the wheelhouse shells were ground through and the sheet on the longitudinal beam blank. The previous owner had also driven 16” times. I painted it. and other wheelhouse shells installed. Greetings Chris
