There are bolt ons and suspension upgrades out there but the name brand stuff thats worth the time is few and far in between. A large deterrent to modding the 9th gen is that the ecu compensates for mods, usually making the engine run rich. The community seems to be waiting for Hondata or Flashpro tuning software. It will take some time. In the mean time, the reflash is a decent WOT tune and eliminates the rev hang.
