From the maximum tire thread on zilvia, im pretty sure I can get them on there, I havent got coilovers yet, so something with the smaller 60mm is it ? springs might be my choice just for that reason, one guy is running 18x9.5 +44's, which would have a hair more backspacing than a 9+44, if anything i'll get them in that offset and run a small spacer if needed. I'm going to be trying to see if i can modify a set of bilstein pss9's to fit from another vehicle, hopefully I can get em to work.
