My 19x12 HRE’s were also rubbing. Scraped the inside wheel weights off in the driveway when first mounted!
I’ve done additional grinding on the Emotion LCA’s and the carrier after each of 3 track days and think I have clearance now.
If you jack up one rear corner and lower it onto a rhino ramp (the raised tire will then be loaded), you’ll see the carrier and arm are much closer to the barrel. I think the rear oem carrier bushing has quite a bit of play.
