Servus! Got a problem and that: After the speedster was in the workshop, he slings, wobbles with the rear part. Only the tyres were changed at the back (the same Bridgestone Potenza were on it as before) Quit or so he does not. Furthermore, he now runs much more extreme after the tracks. What can this be about? Shock absorbers possibly? Anyway, it’s funny that this occurs exactly after the stay in the workshop!!!
