duke, thanks for the input. But would like to know also if a tire's speed rating provide any significant difference. Mine is currently z rated.

haasman, thinking of that also. I will update you of any development if i get to do it. but as an added note, his 300E is not stock. he's using slk wheel with 7 spokes and using tires sized 205/55/R16 front and 225/55/R16 rear .

paulg, if the anti-roll bar rubbers is the same as the sway bar bushings, then, i've already done that. thanks.
