hmmm idk i still have to lower my car but 265/35 work great. i even straighten out my camber but we'll see what i run into when i lower. having bc coilover you should be good. i have ground control coil sleeves. hope you get it figured out bro!
i'm lowered a lil bit i have no issue was gunna lower more next week.
this photo i had 235/40 18x9.5 +15 lowered i had rubbing issues but it worked
have you checked out the wheel thread? it may help! +38 is a decent offset
