how do you add negative camber? i’ve searched them up online for the camber kits and they don’t exist at all from what I can tell. I’m trying to get -6 or -7 camber all around.I used willtheyfit.com for measurement. It's pretty good. I have 18x8.5 +42. It sticks out a few mm and it clears, barely. You will need to add more negative camber for those offsets.
There is someone on the Elantra Sport forum that did 18x9.5 +50 and he didn't complain about rubbing.
