i have a b20 vtec built, my whole dash & door panels shakes like crazy mostly when i go on highway you tell by looking at my car from outside. Any help?
How do i know my engine mounts are bad?
What else should i check except for the mounts?

i think its the engine mounts or torque mount.

 

Hard to tell by your post, but I know if my car was shaking like crazy I would figure it out before I took it onto the highway again.

 

could be your axles. thats what im experinceing right now

 

i have kinda the same problem. do you have an after market intake? that could be the reason why its shaking, my rubber piece is old so i have to change that so its stiffer. if not check your axles i doubt its your mounts but no harm in finding out

 

axles.

 

suspension. hahha
