I'm looking into the jame baron short ram mazda 3 intake for skyactiv motors.one thing that can possibly be done that isn't yet out for the Scion iA is a cold air/short ram intake, shouldn't be that hard to put together.
I did a bit more research on this and went ahead and ordered the DDMWorks rear sway bar. It currently comes with a drill bit to bore out the holes that ours doesn't have. All I did was pre drill the holes with a smaller bit... and then proceeded with the standard installation. Also our rear beam is slightly thicker so I upgraded to a longer bolt. It was an easy install and reduced body roll. Extremely worth the $100!I looked at the rear twist beam, and it doesn't appear to be the same, I wasnt finding the bolt holes they show on rear sway bar setups
