WOW! It took two weeks for Acura to bring in the 17mm rear sway bar after I ordered it but it took me less than an hour to install it laying on my back in the garage. :D I can't believe the improvement in handling! Simply amazing for a 3mm increase over the stock size too. The new bar has approximately 50% greater cross sectional area but gives 100% better driving feel.
