I don't want to be rude however I doubt you are feeling hte Chassis Twisting, Inegra Chassis are pretty stiff and well built I drove me wife's LS on trac stock at high speed and I did not feel the chassis twisting. The creaking you are hering is probably the bushings on the car not the chassis making noise. Strut bars are not really going to much on a stock suspension

 

:werd: without the upgraded suspension your suspension gains will be minimal... yes you will reduce the flex...but you will still have body roll...and it will still creak

 

ah okay. No offense taken. Still laerning. Thanks for the info...Now let me ask, why would a strut bar benefit more with an aftermarket suspension?

Thanks for the info though > i guess i will hold off until i can get new springs and shocks.
