Okay, so I raced at high school drags recently in May (drag racing event). After about 3-4 runs ( i launched my car pretty hard) I drove home. The car shook extremely bad! IT seemed like the whole dash was moving and i glanced over at the passenger seat and it was vibrating like crazy. I was cruising at about 60mph when all this happened. I took it to a mechanic and he drove the car and told me it was either my struts or unbalanced tires. So i got the tires balanced and rotated and that didn't help. So i ordered a set of omin coil overs. The vibration went away for the most part after that, but i can still feel the car vibrating at times usually when i'm cruising or turning. I can feel the vibration in the pedals and my friend can feel it too from the passenger seat. Do you guys think it may be my axles? Or boots? Or something?? I took a look at them and they looked fine??? SOMEONE HELP!!!

 

check your motor mounts.
