Clio 182 cup
Hi guys, I bought a racing blue 182 cup last week and it has this strange thing where on the motorway when doing a steady 70ish occasionally I will start to feel a small vibration and If I accelerate it gets worse and worse and feels like the car is going to rattle its self apart but the second I let off the throttle and put my foot back on the power it’s gone! Even to the point where I can feel the small vibration starting I just blip off an on the throttle and it goes immediately. It had a new front tyre recently so I got the balancing checked on both front wheels and it’s still doing it since! Anyone experienced similar? Only thing I can think is a drive shaft?
