Without a bunch of spacers thats never gonna be "hellaflush". Id start around 18x9 +20 to +30. With a some 225/35s and just a pinch of camber you could probably pull it off. Ill be brutally honest with you, a lot of people jump on the band wagon and pussy out. Not saying you cant do it but its harder than just putting some wheels on, slamming it and calling it a day. I hope you got coils, alot of time and a fender roller. To perfect my stance the first time it took me about 8 hours and that wasnt even to the point where I was happy. Then I got my new set up and It took me more time. Going up and down, up and down, adjusting camber, rolling/pulling the fenders to get the wheels to fit. Oh and prepare to rub, a lot. Also dont forget dumped, stretch, tuckin tire and poking wheel is true hellaflush. Anything else isnt complete.
