Thanks for the info. Can I run stock si springs to lower a tad ?EX-T would be HS (H Street)
To stay there, you can get wheels that are stock width, +/- 1" on diameter, and within 7mm of OE offset. Pretty much any 200tw minimum tire that'll fit.
You can do one swaybar (typically a rear on a Civic.)
You can do an exhaust after the last cat, just has to exit in at least one of the stock locations.
Typically people run the HB Sport in HS because it gets the 8" wheels, you'd be stuck on 7s, but the car should still be plenty fun.
