Hey fellas, I’m planning on running chargespeed fenders which are a +20mm on my IS300. I’m planning on running 17x9 or 17x9.5’s with 255/40R17 all 4 tires. My goal is to make it a somewhat time attack car. What would be the best offsets to run and not rub?

Your specs should be fine. I have seen people run 8.5 +38 no problem. So with a 20mm fender, you should be able to run 9.5 +45/38 to be conservative. +22/15 for more aggressive set up. Depends how meaty the tires you want also.
