I have 295 AD08's on 10" +20. I was on H&R's and it rubbed quite a bit but it was just rubbing away some plastic on the rear bumper, nothing major. Eventually I had no more rubbing unless in comfort EDC mode and I hit a big dip at high speeds.
I'm on Eibach now and I have no rubbing whatsoever under any conditions.
I wanted to put 275/30 on my 9" +22 but someone who has tried it said he rubbed on his shock or something and need a 3mm spacer to make it work.
