Do stock mounts have more rubber between motor and frame?
dang, i just created more work for myself, lol.
ok short version. the mounts you have are harder then the oem ones. the harder the material, the more energy/vibration it transfers.
picture this take a 6" thick piece of hard urethane, hold it on your backside and let your old lady kick it as hard as she can.
now, remove the urethane and hold a 6" thick piece of soft comfy foam up there and let her whack ya again.
well which one do you think you would rather use as an insulater?
ok not, sit in your car and hold the throttle to around 1500 rpm or 1/4 throttle for 15 seconds then do the same at around 2500.
if your engine has an on and off rythmic vibration your engine is not properly balanced.
if your engine has a vibration that is constant but gets noticeably worse with more rpm your engine or clutch/flywheel is not properly balanced.
