i would get the itr rear sway bar because its the thickest (22mm) and also the gsr and itr front sway bar r the same (24mm). with the itr there is a slight adjustment that you need to do. there is a website that shows u how to do it and what you will need. its worth it i think. cause the itr sway bar and all the things u will need will cost less than the suspension techiques stuff
im not sure if this site still works but u can give it a try. the guy that owns the site is on team -integra.net goes by the name BSQ5(from waht i remember) he sells the needed parts for 20 bucks
here is the site
p.s. i had to put a space between team -integra.net because this forum doesnt like that site. just move team over so itll b 1 word
