Excellent handling upgrade for your 01-05 is300, great price and fast super saver shipping from amazon once the item was back in stock. the front sway bar was an absolute bear to replace, with the rear being a piece of cake in comparison. the sway bar set offered a dramatic improvement in handling. these sways should have been offered as a factory upgrade. using this eibach sway bar set with eibach pro-kit springs and tokico illumina struts. highly recommended.
