Car suspension changes? To stop it riding rough
I recently bought a 2015 corolla. I've noticed in runs "rough". The mechanics
told me the suspension was all fine but that the tyres needed replacing. I did
this, and bought 4 x good tyres, but still it runs rough. It feels firm and the
whole car vibrates if I hit a bump or go over bumpy terrain. What can I modify
so it feels softer to ride?
