Hello everyone The Odyssey takes its course. Had actually had to register before next week 18 inches on my ́93 ABT B4 and that with 225/40 tyres. Was earlier at the speedometer check on a test bench for the required paper for the Tüv. The speedometer shows, what is understandable because of the larger roll circumference, too little. At e.g. real 120 driven km/h the speedometer shows only 114. Unfortunately they did not get it to me to put the speedometer on or after. (Was a speedometer?) Opel car house with the only test bench display here far and wide, had no other possibility) Now I am sitting quite nicely in the Bredullie. Do you know perhaps where I can have the speed indicator adjusted in the area Hannover in my speedometer? On the net I find somehow absolutely nothing. To me all the companies dealing with this kind of thing have emigrated because of the new legislation in DE all abroad. Although I do not want to adjust my mileage, what is forbidden I was set to problems with the size of the rims and the tyres/cross-cuts but such a cheese. Would be very grateful for any help!
