I just got my Fit 2 in February and I am trying to figure out whether or not to mod or keep the car. The road noise is loud, but the main issue if I drive too fast (60-80 especially 100kmh) the bumps are so hard is causes some damaged nerves to hurt.

I'm thinking changing these tires to something bigger will help, but the engine is 1.3l.

Other modifications could include sound deadening in some areas and maybe Koni orange shocks.

Other ideas I hade was to change cars. However streets in Japan are small and the best solutions I found were Honda Grace, Toyota Premio, Fit 4(expensive)...

If it's a bigger car it would have to be a Prius or compact SUV, but I would lose access to some streets...

Any advice would be appreciated
