i swear 17x9 plus 20 is the highest offset you can go on a 9 with coilovers in 99% of the cases

just do a 9 plus 20 with 235 40 17 and a slight fender roll not pull and run like 2.5 degrees camber in the front (which s what ou would do for handling anyways) and you will be good


god its not taht hard
