Here's the best photos I have at hand that show the fitment. 18x8+45, sitting 10mm flusher than OEM wheels, is flush enough for me. I don't feel the need to step up to 245's and 8" is perfect for 235 and doesn't sacrifice the tyres rim protection. I also prefer a square shoulder to stretch.I'm thinking to get these in the matte dark gunmetal - how's the fitment on your car? I got 2018 fastback and wanting to go for 18x9 +40. I'll be running them on coil over. Just wanted to know since you've got these ones, do you think going 9inch with +40 offset with very slight camber would work?
I'm not an expert but I would expect 18x9+40 to rub on original suspension. With coilovers I guess it depends on how low you drop and how stiff they are but if it were me I wouldn't risk it. 18x9+40 will be have almost 30mm more poke than OEM.
There are a lot of owners with 8.5" et40 wheels. Some report rubbing, some don't (possible dependant on tyre choice and shoulder profile?). This would be my maximum although they look slightly too flush for my liking, almost protruding from some angles. Some like more poke than others. Personal preference.
Have you considered the 18x8.5 et42 GTC01RR's? They'd have 10mm more poke than mine.
