need help, car vibrating

so i just installed a strut bar on my 06 IS350 and every time i come to a stop the car vibrates pretty bad and when i am stopped and in drive the whole car vibrates. it does not do it when i am in park. i took off my engine cover because it was touching the strut bar and the car still vibrates. the strut bar is not touching anything in the engine so i have no idea why its doing this..? either.

any ideas?

Did you check to see that all bolts were fixed and properly torqued? This shouldn't really be a problem. If anything, it would stiffen everything up.

Are you sure its not just your brakes like if your rotors are out of round . If its all the when driving and it started after the install then check the bolts, but if its only when braking sounds like you may need to replace or cut your rotors

no i know its not the rotors because i drove the car all day and it never happened until i installed it. and even when i am just sitting at a stop sign or red light it vibrates. the bolts are all tight but i didn't use a torque wrench, am i supposed to?

Torque

I think the torque is not alot on that. Like 20-40 lb/ft. If you got it tight, then I guess it's tight. Sure fire way to see what's going on is take some time to remove. If problem goes away instantly, that must be it.
