Wheels, Tires, Brakes, and Suspension
I have a 2015 Q50s, just installed RSR-N123D lowering springs (Down Sus Springs 1.2"- 1.4") and now i get a vibration starting 80km/h and the faster i go the worst it gets.. any ideas of what it could be? im thinking maybe axles and if it is, what should i do as a upgrade or replacement? Thank...
