how to I improve/soften ride?
you might find this funny but go to a performance shop where they modify cars. i know for a fact that they have high quality suspension kit that are Reactive to the speed that you are going. ask them they will find you something. if you can,t find anything I can ask my friend ( high performance garage owner) he will let me know for sure. hope it help's!
You might want to check the PSI of the tires. If you have too much air in the tires it could ride rough. I have another car and the tires say PSI max 51 but I only put in 35 PSI. Just a thought in case you haven't tried that yet.
Bigger tires and/or new suspension.
